Ten chapters for ten topics, and one argument connecting the political half to the industrial one. A set of writers claimed that authority comes from the governed and that rights belong to people as such, and then wrote those claims down, where everyone they excluded could read them. The rest of the unit is what happened as revolutionaries, the enslaved, nationalists, women and factory workers each held that principle to its own terms, against states that were simultaneously being remade by coal.
In 1750 most rulers said their power came from God. A group of writers began asking every old authority the same question, by what right?, and answered it with reason, natural rights and the consent of the people. This chapter follows that question from the new science of the late 1600s to the reformers of the 1800s, and asks how much it had changed by 1900.
The College Board asks two things of this topic. First, explain the ideas that formed the context of the revolutions that swept the Atlantic world. Second, explain how the Enlightenment affected societies over time. Sections 01 to 03 answer the first; sections 04 and 05 answer the second. Each section ends with a tool, a limit and a comparison you can use in an answer.
The Enlightenment's political ideas began with a method. Thinkers learned to test claims about nature with reason and evidence, and then asked whether the same method could test the claims that kings, churches and nobles made about their own power.
In 1750 most of Europe's rulers gave the same answer to the question "who does a state belong to?" It belonged to the king, because God had put him there. This is divine right, the claim Louis XIV made at Versailles (Topic 3.2). In most countries one church was the law: Catholic in France and Spain, Anglican in England. Nobles were born into privileges, such as freedom from some taxes, and across much of central and eastern Europe peasants were serfs, bound to work their lord's land. Authority came from God, from tradition and from birth.
In 1687 the English scientist Isaac Newton published a book showing that a few laws of motion and gravity, worked out with mathematics and tested against what astronomers observed, explained both the paths of the planets and the fall of an apple. The lesson many readers took from it was that the world runs by laws a human mind can discover, without being told by an old book or a priest.
In 1689 the English philosopher John Locke argued that every idea in our minds comes from experience. At birth, he wrote, the mind is like "white paper." Learning from evidence and experience instead of accepting what authorities say is called empiricism. Scientific lectures and experiments became popular entertainment for people who could pay, like the family in Joseph Wright's painting of an air-pump experiment, made famous by a print of 1769.
The step that made the method political was simple to state. If reason and evidence can explain the planets, can they explain people: how we should live together, what a government is for, and what makes a ruler's power rightful? Enlightenment writers turned the method on government, religion, law and society, and that is where the new political ideas came from.
Enlightenment writers started with the individual person, not the king, and came up with new answers to the question of what makes power rightful. The change was not that kings disappeared; it was that a ruler now had to answer the question.
In his Second Treatise of Government (1689), Locke argued that people are born free and equal, with natural rights to their "lives, liberties and estates" (an estate is what you own). No government gives these rights, and no government may take them. People form a government to protect them.
That makes government an agreement, a social contract. "No one," Locke wrote, can be "subjected to the political power of another, without his own consent." And if a government tries to destroy the people's rights or reduce them to slavery, it puts itself "into a state of war with the people," who no longer owe it obedience. Most historians think Locke wrote most of the book in the early 1680s, when some members of Parliament were trying to keep the Catholic James from becoming king, and he published it in 1689, just after Parliament had replaced James II. Both times, his argument defended the right to resist a king.
In 1762 Jean-Jacques Rousseau, a writer from Geneva who lived in France, began The Social Contract with a famous line: "Man is born free; and everywhere he is in chains." Rousseau argued that rightful power comes from the "general will" of the people as a whole, a more collective idea than Locke's.
In The Spirit of the Laws (1748), the French writer Montesquieu argued that liberty is safest when the power to make laws, the power to carry them out and the power to judge are held by different people, so that one power can check another. This is the separation of powers.
In 1762 a court in Toulouse condemned Jean Calas, a Protestant cloth merchant, for killing his son to stop him from becoming a Catholic. His son had most likely taken his own life. Calas was tortured and executed. Voltaire, one of the most famous writers in Europe, took up the case, published a Treatise on Tolerance in 1763, and campaigned until Calas was declared innocent in 1765. The argument was religious toleration: no government should force a faith on anyone or punish people for what they believe.
The ideas spread through print and conversation across Europe and the Atlantic, questioned tradition in every part of life, and came before the revolutions that began in 1775, 1789, 1791 and 1810. They gave revolutionaries their words, and they turned "the people" into the nation.
From 1751 to 1772, Denis Diderot and his partners published the Encyclopédie in Paris: seventeen volumes of articles and eleven of pictures that tried to explain everything by reason, from how to make glass or mount a fan to what a government owes its people. The French government banned it in 1759, and the Pope condemned it, but the last ten volumes of articles came out together in 1765, and printers in other countries copied it: a second edition was printed in Lucca, Italy, from 1758.
The ideas also traveled in newspapers and pamphlets, in London's coffeehouses, in letters between writers across Europe and the Americas, and in the conversation gatherings of Paris called salons, which were often run by women. In 1784 the German philosopher Immanuel Kant summed up the attitude in a motto: "Dare to know," which he explained as having the courage to use your own understanding.
The College Board's words are that Enlightenment thought "often preceded" revolutions. The American Revolution began in 1775, the French Revolution in 1789, the Haitian Revolution in 1791, and the wars of independence in Spanish America in 1810. In Bogotá, Antonio Nariño secretly printed a Spanish translation of France's new declaration of rights (in 1793 or 1794) and was arrested for it in 1794; he later became one of the leaders of New Granada's independence.
If a state belongs to its people, a new question follows: which people? More and more, the answer was the nation, a people who saw themselves as one (Topic 5.2 explains what held a nation together). In 1789 the French revolutionaries wrote that "the principle of all sovereignty resides essentially in the nation." Over the next century, nationalism, loyalty to your nation above a king or an empire, became one of the strongest forces shaping states and empires: it helped build new countries and pulled at empires of many peoples. Topic 5.2 tells that story.
The words sounded like everyone, but the men who wrote them often did not mean everyone. Over the next century, reform movements driven by Enlightenment ideas and by religious faith pressed the same words until rights reached the enslaved, the serfs and many more voters, slowly and unevenly.
Locke owned shares in the Royal African Company, an English company that traded enslaved Africans, in the 1670s. Rousseau wrote in Emile (1762) that "a woman's education must therefore be planned in relation to man." Most of the men who wrote and read the new ideas did not mean them for women, enslaved Africans or peasants, though a few did: the French philosopher Condorcet argued for women's rights in 1790. Yet the words were written down, and anyone could ask the philosophers' own question: by what right am I left out?
In 1787 twelve men in London, nine of them Quakers, a Christian group whose members had come to see slavery as a sin, founded the Society for Effecting the Abolition of the Slave Trade. Its seal showed a kneeling African man in chains and the words "Am I not a man and a brother?", and the potter Josiah Wedgwood turned it into a medallion that supporters wore. Olaudah Equiano, who had been enslaved, published his life story in 1789 and traveled across Britain speaking against the trade.
Abolition came country by country. Britain banned the slave trade in 1807. In 1834 it began ending slavery in most of its empire, though freed people had to keep working for their former owners as unpaid "apprentices" until 1838. France abolished slavery in its colonies in 1794, brought it back in 1802, and ended it again in 1848. Brazil was the last country in the Americas, in 1888. The enslaved people of Saint-Domingue ended slavery there by revolution, which is Topic 5.2.
Serfdom ended too. In 1848 the Austrian Empire freed its peasants from the forced labor they owed their lords. In 1861 Tsar Alexander II of Russia freed more than 20 million serfs. He had reportedly told Russian nobles in 1856 that it was better to end serfdom "from above" than to wait for it to end "from below," and Russia's defeat in the Crimean War pushed him too. The freed serfs had to pay for their land over many years.
Suffrage, the right to vote, widened in steps. In 1848 France gave the vote to all adult men. Britain widened voting among men in 1832, 1867 and 1884, and even then many men could not vote.
Women pressed the same words too, because the men who wrote about the rights of man often meant only men. Their demands challenged both political and gender hierarchies. By 1900 much had changed, and much had not.
In September 1791 the French writer Olympe de Gouges rewrote France's declaration of rights as the Declaration of the Rights of Woman and of the Female Citizen. Where the declaration of 1789 said "men are born and remain free and equal in rights," her first article said: "Woman is born free and remains equal to man in rights." The revolutionary government executed her in November 1793.
In 1792 the English writer Mary Wollstonecraft published A Vindication of the Rights of Woman. She quoted Rousseau, who had warned that if women were educated like men, "the less power will they have over us," and answered: "I do not wish them to have power over men; but over themselves." Her claim was that women can reason, so they must be educated to think and decide for themselves.
In 1840 the American abolitionist Lucretia Mott, a Quaker minister, went to an antislavery convention in London as a delegate and was refused a seat because she was a woman. Elizabeth Cady Stanton, there with her husband, a delegate, sat with Mott and the other women, apart from the men. In July 1848 the two of them, with three other women, organized a women's rights convention in Seneca Falls, New York. Its Declaration of Sentiments, drafted by Stanton with members of the M'Clintock family, copied the Declaration of Independence and added two words: "all men and women are created equal." It complained that a woman had never been "permitted ... to exercise her inalienable right to the elective franchise," the vote. The resolution demanding the vote was the only one not passed unanimously; one hundred women and men signed the declaration.
This was feminism emerging: the claim that women and men should have equal rights. It challenged political hierarchy, who votes and who rules, and gender hierarchy, who is in charge at home and under the law. Under the law of the time, the Seneca Falls declaration complained, a married woman was "civilly dead."
By 1900, kings and emperors still ruled most of Europe and much of the world, many of them sharing power with elected parliaments. Slavery had been abolished across the Americas, but other kinds of forced labor went on in many places. Many countries let some or all men vote. Women could vote in national elections almost nowhere: New Zealand, in 1893, was the first self-governing country where all adult women could vote in national elections.
So the Enlightenment changed the answer to "who does a state belong to?": to its people, by reason and consent, not to a king by God's will. The question it taught people to ask kept working long after the philosophers were gone. That is the change. How slowly the rights reached, and how many people were still waiting in 1900, is the continuity.
Each card gathers the evidence for one part of the answer. The first two answer Learning Objective A, the ideas as the context of the revolutions; the last two answer Learning Objective B, what the Enlightenment did to societies over time.
Before the Enlightenment, rulers said their power came from God, tradition and birth. Locke argued in 1689 that people are born with natural rights and that no one may be put under a government's power without consent; Montesquieu (1748) argued for the separation of powers, and Voltaire (1763) for religious toleration. What changed was what made a ruler legitimate. What continued was that kings still ruled almost everywhere.
The ideas spread through the Encyclopédie (1751 to 1772, banned in France and reprinted in Italy), salons, coffeehouses and letters, and came before the revolutions of 1775, 1789, 1791 and 1810. Nariño's printed translation of the French declaration in Bogotá shows them crossing the Atlantic. If a state belongs to its people, the people could be the nation, and nationalism became a major force of the 1800s.
Driven by natural rights and by faith, reformers founded the London antislavery society of 1787 (nine of its twelve founders were Quakers). Britain began ending slavery in most of its empire in 1834 and Brazil, last in the Americas, in 1888. Serfdom ended in Austria in 1848 and Russia in 1861; France gave all adult men the vote in 1848. Each change took decades.
De Gouges (1791) wrote that "woman is born free and remains equal to man in rights"; Wollstonecraft (1792) wanted women to have power "over themselves"; the Seneca Falls declaration (1848) said "all men and women are created equal" and demanded the vote. Their claims challenged political and gender hierarchies, but by 1900 women could vote in national elections almost nowhere.
By 1789 the new ideas about rights were everywhere educated people read, but ideas alone never overthrew a king. This chapter follows four revolutions, in America, France, Haiti and Spanish America, asks what caused each one and what it created, and then follows the loyalty they left behind, to the nation, through the rest of the 1800s.
The College Board asks you to explain the causes and effects of the revolutions between 1750 and 1900. Sections 01 to 04 take the four revolutions of the Atlantic world one at a time, each with its grievance, its words, its chance and what it created. Section 05 follows two lasting effects, new ideas about government and the nation, to 1878. Each section ends with a tool, a limit and a comparison you can use in an answer.
Many people read Enlightenment writers and went on obeying their kings. A revolution came when three things met: a grievance many people felt, the words to name it, and a chance to act. America had all three first.
Topic 5.1 showed that the new ideas about natural rights and the consent of the people had spread across Europe and the Americas by 1789. But reading a book is not the same as risking your life. Across this topic, three ingredients turn up again and again. The first is a grievance: a wrong that many people feel, such as an unfair tax, a privilege for a few, slavery, or a law that shuts people out of power. The second is the words: a document that names the grievance in the language of rights, something people can read aloud and rally around. The third is a chance: a moment when the old ruler is broke, far away, at war, or gone.
Britain won the Seven Years' War in 1763, but it came out of the war deep in debt. Parliament decided its thirteen American colonies should help pay for the soldiers who guarded them, and it taxed them with laws such as the Sugar Act of 1764 and the Stamp Act of 1765, which taxed newspapers, legal papers and playing cards. The colonists had no members in Parliament, so they answered with a slogan: "no taxation without representation." Protest reached ordinary homes: English potters even sold colonists teapots painted "No Stamp Act."
On 4 July 1776 the Continental Congress adopted the Declaration of Independence. It argued that "all men are created equal," that governments get "their just powers from the consent of the governed," and that when a government destroys people's rights, "it is the Right of the People to alter or to abolish it." That is the social contract from Topic 5.1, turned into a reason to break away.
Britain was an ocean away, and its victory in 1763 had pushed France out of North America, so the colonists no longer needed British soldiers to protect them. Once the fighting began in 1775, France, Britain's old rival, joined the war on the American side in 1778 with money, soldiers and a navy, which helped the colonists win. By 1783 Britain had recognized the independence of the United States. In 1787 the new country wrote a constitution for a republic: a country with no king, whose leaders are elected.
The College Board calls the American Revolution and its republic "a model and inspiration for a number of the revolutions that followed." It was also limited. The republic kept slavery, and most states let only men who owned property vote.
France's help was crucial to the American victory, and paying for it, on top of older war debts, pushed the French king to the edge of bankruptcy. One revolution's effect became the next one's chance.
France had spent heavily on the American war, on top of the debts of earlier wars, and by 1788 King Louis XVI's government was nearly bankrupt. To raise new taxes, the king called the Estates-General, an assembly of the three "estates" of France: the clergy, the nobles, and everyone else. It had not met since 1614.
The first two estates had privileges. The clergy and the nobles paid little in taxes, and the Third Estate, most of the people of France, from rich lawyers to poor peasants, paid most of them. After a bad harvest in 1788, the price of bread, the main food of the poor, soared. When the Estates-General met in May 1789, the Third Estate refused to be outvoted by the other two, and in June it declared itself the National Assembly. On 14 July a Paris crowd stormed the Bastille, a royal fortress and prison, to seize its gunpowder.
In August 1789 the Assembly ended the nobles' special privileges and adopted the Declaration of the Rights of Man and of the Citizen. Its first article reads, "Men are born and remain free and equal in rights." Its third reads, "The principle of all sovereignty resides essentially in the nation." Sovereignty is the highest power in a state, and the declaration said it belonged to the nation, not to the king.
France abolished its monarchy in 1792 and became a republic, and in January 1793 it executed the king. At war with much of Europe and afraid of enemies at home, the government began the Terror (1793 to 1794), during which it killed thousands of people it called enemies of the revolution. In 1799 a general, Napoleon Bonaparte, took power, and in 1804 he crowned himself emperor. His armies carried the revolution's laws, such as the end of noble privilege, across Europe, and they also made many Europeans hate French rule.
France's declaration said men are born free and equal. In Saint-Domingue, the people France held in slavery claimed those words for themselves, rose up first, and won a country of their own.
Saint-Domingue, on the western part of the Caribbean island of Hispaniola, was France's most valuable colony. Its sugar and coffee were grown by enslaved Africans and their children, worked and punished brutally on plantations. Around 1789 the colony held more than 400,000 enslaved people and fewer than 80,000 free people, white colonists and free people of color (free people of African or mixed descent) together: more than five enslaved people for every free person.
When the 1789 declaration reached the colony, free people of color asked the Assembly in Paris for the equal rights it promised. The Assembly left the question to the colonists, and the white planters refused. In 1790 a free man of color, Vincent Ogé, led a small revolt for those rights, and early in 1791 he was executed. Paris granted free people of color equal rights only in April 1792, after the revolution in the colony had begun.
With France in revolution and the colony's white planters divided, enslaved people in the northern plain rose up in August 1791. They burned plantations across the northern plain. Toussaint Louverture, who had been born enslaved and had won his freedom before the revolution, became the revolution's most famous leader. In 1793, fighting on Spain's side against France, he announced: "I want Liberty and Equality to reign in Saint Domingue."
In 1802 Napoleon brought slavery back in other French colonies, such as Guadeloupe, and sent an army to retake Saint-Domingue. Toussaint was arrested and died in a French prison in the mountains in 1803. His officer Jean-Jacques Dessalines fought on, and yellow fever and the war destroyed the French army. On 1 January 1804 Dessalines declared independence and gave the country its old Taíno name, Haiti.
Haiti was the second independent country in the Americas, after the United States, and the first founded by people who had freed themselves from slavery. Its effects reached other countries. In April 1803, with his army in Saint-Domingue dying of yellow fever and a new war with Britain coming, Napoleon sold Louisiana to the United States. Countries that allowed slavery feared Haiti's example: the United States did not recognize Haiti until 1862, and in 1825 France demanded 150 million francs, later cut to 90 million, as the price of recognizing Haiti's independence. And in 1816 Haiti helped the next revolution (section 04).
Creoles in Spain's American empire had grievances for decades. Their chance came when Napoleon, the French Revolution's general, took Spain's king, and the last revolution's creation, Haiti, helped them win.
In Spain's American empire, creoles, people of Spanish descent born in the Americas, owned land, mines and businesses, but the highest offices in the church, the army and the government went to peninsulares, men born in Spain. Spain also controlled what the colonies could grow, make and trade. Simón Bolívar, a creole from a rich Caracas family, wrote that Spain "has kept us in a sort of permanent infancy with regard to public affairs": treated like children, kept out of running their own affairs.
In 1808 Napoleon invaded Spain and forced its king from the throne, putting his own brother in his place. Spanish America suddenly had no rightful king to obey. In 1810 creole leaders set up governments of their own, in Caracas and in Buenos Aires, at first in the name of the captive king, and many soon moved to full independence. In Mexico a priest, Miguel Hidalgo, called on Native and mestizo villagers to rise up.
The wars went badly at first. In 1815, beaten and in exile on the British island of Jamaica, Bolívar wrote a long letter to a British reader, now called the Letter from Jamaica. "The hatred that the Peninsula has inspired in us," he wrote, "is greater than the ocean between us," and the tie to Spain "has been severed." He also doubted that governments "wholly representative," chosen entirely by the people's votes, suited Spanish America yet.
Then Haiti helped. In 1816 Haiti's president, Alexandre Pétion, gave Bolívar guns, supplies and men for a new expedition, and asked him in return to end slavery in the lands he freed.
By 1826 Spain had lost every colony in the Americas except Cuba and Puerto Rico. Mexico, Gran Colombia, Peru, Chile, the provinces of the Río de la Plata and others became independent countries, and Brazil broke away from Portugal in 1822 with an emperor of its own. Creole elites took the top places. Most of the new countries kept a sharp social hierarchy, and slavery lasted in several of them for decades: Colombia ended it in 1851, Venezuela and Peru in 1854.
Some of the revolutions' longest-lasting effects were ideas: new answers to how a country should be run, and a new loyalty, to the nation, that joined some states together and pulled peoples away from empires.
Behind all four revolutions was anger at kings and empires, and the revolutions left behind new answers to an old question: how should a country be run? One was the republic, with a written constitution, a set of basic laws that even the government must follow. Another was liberalism: the belief that a constitution and an elected parliament should limit the government and protect each person's rights, such as free speech, a free press and property. Many liberals in the 1800s still wanted only men with property to vote. A third was democracy, rule by the people, which pushed for the vote to reach all men.
These ideas did not stay on paper. They helped set off new revolutions across Europe in 1830 and 1848, when crowds demanded constitutions, parliaments and wider voting. Most of the uprisings of 1848 were crushed within two years, but the demands did not go away.
The revolutions said that a state belongs to its people. That raised a new question: which people? More and more, people answered with the nation: everyone who shared a language, a religion, customs and a homeland. Nationalism put loyalty to the nation above loyalty to a king or an empire.
Governments learned to use that loyalty. In 1793, at war with much of Europe, revolutionary France ordered that "all Frenchmen are in permanent requisition for the service of the armies": young men would fight, married men would make weapons, women would make tents and work in hospitals, and old people would go to public squares to preach "the unity of the Republic." But nationalism could also be turned against a government, by people who felt they were a nation without a country of their own.
Italy was split into several states, some ruled by Austria. Italian nationalists, among them Count Cavour, the chief minister of the kingdom of Piedmont-Sardinia, and the soldier Giuseppe Garibaldi, whose volunteers took Sicily and Naples in 1860, joined most of Italy into one kingdom in 1861, and added Rome in 1870. Joining states into one is called unification.
Germany was split into more than thirty states. In 1848 German liberals met in Frankfurt to unite Germany with an elected parliament and a constitution, and failed. Then Otto von Bismarck, the chief minister of Prussia, told Prussia's lawmakers in 1862 that the great questions of the time are not decided "by speeches and majority resolutions," which had been "the big mistake of 1848 and 1849," but "by iron and blood." After three wars, against Denmark, Austria and France, the German Empire was proclaimed on 18 January 1871 in the Hall of Mirrors at Versailles, the palace Louis XIV built.
The Ottoman Empire ruled many peoples in the Balkans, in southeastern Europe, Muslim and Christian. Serbs rebelled and won the right to rule themselves. Greeks rose up in 1821, and in 1830 Britain, France and Russia declared Greece an independent state; it became a kingdom under a Bavarian prince in 1832. Other Balkan peoples followed, and in 1878 Serbia, Montenegro and Romania were recognized as independent.
The Ottoman government answered with a loyalty of its own, Ottomanism. In 1856 it promised equal treatment to all its subjects, Muslim or not, and in 1869 a law made every subject an Ottoman citizen. The idea was one loyalty for everyone, to the empire, instead of to a nation. It did not stop the Balkan nations from leaving. The idea reached beyond Europe, too: in the Spanish-ruled Philippines, Filipino writers in the Propaganda Movement of the 1880s and 1890s, José Rizal among them, demanded equal rights with Spaniards, and Spain executed Rizal in 1896, during a revolution against its rule.
Each card gathers the evidence for one part of the answer. The College Board asks for causes and effects, so the first two cards are causes and the last two are effects.
Evidence to sort: the Stamp Act (1765); the end of the French threat in North America (1763); the Declaration of Independence (1776); noble privilege and bread prices in France (1788 to 1789); a bankrupt French government (1788); the Declaration of the Rights of Man (1789); slavery in Saint-Domingue; the rising of 1791; Toussaint's proclamation (1793); creoles kept out of high office; Napoleon's invasion of Spain (1808); Bolívar's Letter from Jamaica (1815). For the revolution you choose, decide which is its grievance, which gave it words, and which was its chance.
Evidence to sort: France's spending on the American war; free people of color in Saint-Domingue and France's 1789 declaration; Napoleon's invasion of Spain (1808); Haiti's guns, supplies and men for Bolívar (1816). For each, name the two revolutions it links and decide whether it helped the second one start or helped it win. The College Board calls the American Revolution "a model and inspiration for a number of the revolutions that followed."
The United States (1783, a republic under the 1787 constitution), Haiti (1804) and the independent countries of Spanish America (by 1826) were new states. Republics, written constitutions, liberalism and democracy were new ideas, which helped set off new revolutions in Europe in 1830 and 1848. Many things stayed: slavery in the United States and much of Latin America, and creole elites at the top.
Evidence to sort: France's 1793 order calling "all Frenchmen" to serve the armies; the liberals at Frankfurt (1848 to 1849); Bismarck's "iron and blood" (1862); Italy joined into one kingdom (1861), and Rome added (1870); the German Empire (1871); Britain, France and Russia declaring Greece independent (1830); Serbia, Montenegro and Romania recognized as independent (1878); the Ottoman edict of 1856 and the citizenship law of 1869. Decide which show nationalism joining states, which show it pulling peoples from an empire, and which show a government using or answering it.
Even before Paris argued about rights, a different revolution had begun in Britain: a change in how things were made. This chapter asks why it began there. Part of the answer was in Britain's ground and water, and the rest was built by people. Then it follows the new workplace those causes produced, the factory, and the two things it changed about work.
The College Board asks you to explain how environmental factors contributed to industrialization. Its list has seven factors. Sections 01 and 02 take the two that nature gave Britain; sections 03 and 04 take the five that people built, and show them working together; section 05 follows the new workplace they produced. Each section ends with a tool, a limit and a comparison you can use in an answer.
Britain had plenty of coal and iron, often close together and close to water, and too little wood. The shortage of wood pushed Britons to burn coal, and then to make iron with it.
In 1750 almost everything people owned was made by hand. Most thread and cloth were made in homes. Under the putting-out system, a merchant brought raw wool or cotton to families in the countryside, who spun and wove it on their own wheels and looms, and he came back to collect the work and pay for each piece. Power came from human muscles, horses, wind and water wheels. Much of the world's cotton cloth came from India, and Britain's cotton makers grew up copying it.
Over the next century Britain built a new way of making things. The College Board lists seven factors that led to it. Two come from nature: waterways, and where coal, iron and timber were found. Five were built by people: towns, better farming, laws that protected property, resources from abroad, and saved-up money. This chapter takes them in that order.
By the 1600s most of Britain's old forests had been cut down, as a growing population cleared land for farms. Wood became expensive. That mattered, because wood was the fuel of the old economy. It heated homes, and it made charcoal, the fuel used to heat iron ore until the iron could be separated out. Much of the iron Britain used was bought from Sweden, and later from Russia, where forests were still large.
Britain did have coal, in huge beds, much of it close to the surface and close to rivers or the sea. So Britons burned coal instead of wood. By 1700 coal gave England about half of all its energy, much of it burned in fireplaces for heating and cooking.
Coal could not simply replace charcoal in an iron furnace: its impurities spoiled the iron. In 1709, at Coalbrookdale, a valley beside the River Severn in Shropshire, Abraham Darby made iron using coke, a fuel made by baking coal to drive the impurities off. Coalbrookdale had coal and iron ore close by and a river to carry what it made. At first coke iron was used mostly for cast-iron pots. It spread slowly, mainly after the 1750s, as charcoal iron and imported iron grew dearer, and over the following decades ironmakers learned to make better iron with coal.
Before railways, the cheapest way to move something heavy was to float it, and the fastest way to power a machine was a water wheel. Britain had coast, rivers and fast streams, and people added canals.
Coal is heavy, and so is iron. Carrying them by cart on the roads of the 1700s was slow and expensive. Carrying them by water was cheap. Britain had a long coastline and rivers that boats could travel, and coal from the mines near Newcastle went by ship down the coast to London.
Fast streams mattered too. A stream could turn a water wheel, and a water wheel could turn machines all day. The first factories were built beside fast water, as section 05 shows.
Where nature had put no river, people dug one. A canal is a waterway dug by hand. The Duke of Bridgewater owned coal mines at Worsley, a few miles from Manchester. In 1759 and 1760 Parliament passed acts allowing him to build a canal. In 1761 it opened from Worsley to Stretford, on the edge of Manchester, and the price of coal in Manchester soon fell by about half. By 1765 it reached the town itself.
Other canal builders followed. Within a few decades canals linked coalfields, industrial towns and ports across England. Cheap fuel and cheap carriage drew mills to the places the water reached.
British farmers grew more food on the same land. More food fed more people, a smaller share of them farmed, and towns filled with workers and buyers.
Farmers had long left fields empty every few years to let the soil rest. British farmers learned to plant turnips and clover instead. Turnips fed cattle and sheep through the winter, and clover made the soil richer. More animals meant more manure for the fields, and more manure meant more grain. These crops had been grown this way in Flanders first; British farmers spread them.
Landowners also fenced off the old shared village fields into private farms, often with an act of Parliament. Between 1750 and 1819 Parliament passed more than three thousand of these acts. This enclosure let a landowner farm his land the new way. It also took away the shared land that poorer villagers had used, and historians still argue about how many people it pushed off the land.
More food fed more people. Britain's population grew from about 8 million in 1761 to about 10.5 million in 1801, the year of the first census. And a smaller share of those people farmed: in 1700 almost half of English working men worked on the land, and by about 1800 estimates range from about a third to about two in five.
Many of the people who did not farm lived in towns. Urbanization, the growth of towns and cities, put many workers close together, and gave them neighbors to sell to. Manchester, a town of about 23,000 people in 1773, counted 70,409 in the census of 1801.
Building a mill was a big risk. Laws that protected property, cotton from abroad and saved-up money made the risk worth taking, and the factors worked together.
In Britain, Parliament, where landowners and merchants sat, passed the laws that enclosed fields and allowed canals to be dug. A law of 1624 banned most monopolies but kept the patent: the crown could grant the true and first inventor the sole right to use a new invention for up to fourteen years. In 1769 Richard Arkwright patented a new spinning machine. A person who invested could expect the law to protect what he built.
The protection had limits. Arkwright's 1769 spinning patent ran out in 1783, and in 1785 a court canceled his 1775 patent on his carding and preparing machines, finding his written description of them unclear; the court also heard claims that other men had invented them.
Cotton does not grow in Britain's climate. By the 1780s most of the cotton spun in Manchester was grown by enslaved people on plantations in the Caribbean and South America. After the 1790s more and more of it came from plantations in the United States. Britain used about 2.6 million pounds of raw cotton in 1760, almost all of it spun by hand, and about 51.6 million pounds in 1800. The factory's raw material came from far away, and most of it was grown by people who were not free. (In the 1780s a quarter or more came from the Ottoman Empire, through the port of Smyrna.)
Capital is money used to build something that makes more money. Merchants, bankers and landowners had grown rich from trade, including the Atlantic trade in enslaved people and the sugar they grew, and some were ready to risk their savings on mills and machines. Arkwright's partners, Samuel Need and Jedediah Strutt, were stocking makers who had grown rich in the hosiery trade. The partners spent thousands of pounds on machines and mills before the business made a profit, at a time when a carpenter earned no more than about £36 a year.
None of these factors made an industrial revolution by itself. Watch five of them meet in one project. The Bridgewater Canal needed coal under the ground at Worsley (nature). It needed water to float the coal on (nature, improved by people). It needed acts of Parliament, passed in 1759 and 1760, to allow it to be built (law). It needed the duke's money, and he had to borrow more to pay his workmen (capital). And it needed a growing town to buy the coal (urbanization). Cheap coal then made Manchester an even better place to build mills, and the new mills made the town grow faster still.
The factors made it pay to build mills. The factory then changed work itself in two ways: it gathered production in one place, and it split the work into small, specialized jobs.
In 1771, Arkwright and his partners built a cotton-spinning mill at Cromford, in Derbyshire's Derwent valley. A water wheel turned the machines. It was fed by a brook and by the Cromford Sough, a tunnel that drained the nearby lead mines; because its water came from underground, it was said never to freeze.
The mill did not send cotton out to spinners' homes. It brought the workers to the machines. Everyone came to one building, at the hours the mill set, under the eye of an overseer. The village was too small to supply enough workers, so Arkwright built houses for them. Most of his workers were women and children, some as young as seven. This was the factory system: production concentrated in a single place, around one source of power. UNESCO, which protects the valley as a World Heritage Site, says it "saw the birth of the factory system."
Inside a cotton mill, the work was split into steps. Raw cotton was cleaned, then carded (combed so its fibers lay straight), drawn out, twisted into a loose rope called roving, and spun into thread. Cromford began with machines for spinning, and in 1775 Arkwright patented machines for the earlier steps too. From then on each step after cleaning had its own machine, tended by workers who did that job and no other. This is specialization of labor.
Adam Smith, a Scottish thinker, showed why it mattered in 1776, using a small hand workshop that made pins. Ten men shared about eighteen steps, each doing only one, two, or three of them, and together they "could make among them upwards of forty-eight thousand pins in a day." A worker who had not learned the trade, working alone, he wrote, "could scarce ... make one pin in a day, and certainly could not make twenty." Because each job was small and simple, it could be learned quickly, so a mill could hire workers with no training, many of them children.
Each card gathers the evidence for one part of the answer. The College Board asks how environmental factors contributed to industrialization, so the first card is the environment, the next two are what people built and how the factors combined, and the last is the factory system.
Evidence to sort: coal and iron close together and close to water; a shortage of wood by the 1600s; iron bought from Sweden and later Russia; coal giving England about half its energy by 1700; Darby's iron made with coke (1709); coast and rivers; fast streams and water wheels; the Bridgewater Canal (opened 1761) and the price of coal in Manchester. For each, say what it made cheaper or possible.
Evidence to sort: turnips and clover; enclosure acts; Britain's population (about 8 million in 1761, about 10.5 million in 1801); a falling share of English men farming (almost half in 1700, a third to two in five by about 1800); Manchester (about 23,000 in 1773, 70,409 in 1801); the patent law of 1624 and Arkwright's patent of 1769; cotton grown by enslaved people in the Caribbean, South America and the United States; capital from trade; Need and Strutt. For each, say how it made a mill worth building.

In 1750 most of the world's goods were made by hand, and most of them in Asia. Then the factory left Britain. This chapter follows how it traveled and where it took root, how the world's shares of manufacturing moved, and what the old makers kept making while their share shrank.
The College Board asks you to explain how the ways goods were made, and the places they were made, changed between 1750 and 1900. That is a continuity-and-change question. Section 01 sets the starting point; sections 02 and 03 follow the change in places; section 04 measures the change; section 05 is the continuity, and why the old makers' share fell. Each section ends with a tool, a limit and a comparison you can use in an answer.
In 1750 almost everything was made by hand, at home or in workshops, and most of the world's manufactured goods were made in China and India.
In 1750 a shirt, a pot, a plow or a ship was made by people using hand tools, at home or in small workshops. This is hand production. Power came from muscles, animals, wind and water wheels. That was true in Britain, too: Arkwright's mill at Cromford was still twenty years away.
The places that made the most were the places with the most people and the most skilled craftworkers. India's cotton cloth, from fine thin muslins to cheap printed calicoes, was sold across the Indian Ocean, in the Middle East, in West Africa and in Europe. Chinese silk, porcelain and cotton cloth filled China's own huge markets and traveled abroad. Indian shipbuilders built ocean-going ships of teak.
Nobody counted every piece of cloth in the world in 1750. But the economic historian Paul Bairoch made careful estimates, working backward from what is known about people and their work. He estimated that around 1750 China made about a third of all the world's manufactured goods and India about a quarter. All of Europe together made about a quarter. Britain made under 2 percent.
Britain tried to keep its new methods at home by law. They left anyway, first in the heads of skilled people.
Britain's leaders knew the new machines were worth a great deal. British law banned skilled workers in the textile trades from leaving to work abroad, and banned the export of textile machines. The ban on workers leaving was repealed in 1824; the last bans on exporting machinery were lifted in 1843.
Samuel Slater learned the cotton trade as an apprentice at Jedediah Strutt's mill at Belper, in Derbyshire. Strutt had been Arkwright's partner, and his mills ran Arkwright's machines, so Slater learned them from the inside. In 1789 he sailed for the United States without telling anyone what he knew. At Pawtucket, Rhode Island, working with American merchants, he built water-powered spinning machines from memory. The mill that still stands there was begun in 1793 and enlarged several times afterward.
In Belgium, John Cockerill, the son of an English machine maker, began building machines at Seraing, near Liège, in 1817, and added ironworks there in the 1820s. Liège sat on one of the richest coalfields on the continent of Europe, with rivers to carry goods. The pattern from Topic 5.3, coal near water, was waiting there.
Machines and money carried the methods too, and most took root near coal, or by rivers that could turn wheels: in other parts of Europe, in the United States, and later in Russia and Japan.
The first steam railway in the German states, from Nuremberg to Fürth, opened in 1835 with a locomotive built in England. On the continent, factories grew where coal lay, as they had in Britain: around Liège in Belgium, in the Ruhr valley of the German states, and in northern France.
In the United States, wealthy Boston merchants paid for big cotton mills at Lowell, Massachusetts, from the 1820s, beside a river that could turn their wheels. Most of the workers were young women from New England farms. By 1900 the United States made more of the world's manufactured goods than any other country.
Russia and Japan came later, mostly after 1870. A Welsh engineer, John Hughes, built ironworks in the coal country of the southern Russian Empire, in what is today eastern Ukraine, in the early 1870s; the town that grew up around them was named Yuzovka, after him (today Donetsk). In Japan the Osaka Spinning Company opened in 1883 with cotton-spinning machines made in Britain, driven by steam power, and it ran day and night.
India, China and the Middle East kept making cloth, ships and other goods, much of it by hand. Their share shrank because the rest of the world made far more, because machine-made goods were cheaper, and because of the trade rules of the people in power, among other causes historians still argue about.
In India, hand weaving shrank, but it did not die. Weavers kept working cloth on handlooms, and many switched to cheaper machine-spun thread so they could keep weaving. The economic historian Tirthankar Roy finds that handloom cloth held a roughly steady share of India's cloth market from the 1890s to the 1930s, and in 1908, in one province of northern India alone, about a million people still lived from handloom weaving. In China, farm families kept weaving cloth at home, more and more of it from cheaper machine-made thread. In the Ottoman Empire, the number of handlooms in the Syrian cities of Aleppo and Damascus held steady from 1860 to 1914.
Indian shipbuilders kept building, too. At the Bombay dockyard, the shipyard of the city now called Mumbai, the Wadia family of master shipbuilders built teak warships for Britain's own Royal Navy. One of them, HMS Trincomalee, launched in 1817, is still afloat today in Hartlepool, England, where its museum calls it Britain's oldest warship still afloat.
One reason the share fell is that the rest of the world made far more goods. Another is that the old makers lost buyers. Cloth from Lancashire's machines was cheaper than cloth woven by hand, even in India itself. In 1815 India sold about £1.3 million worth of cotton cloth abroad and bought only about £26,000 worth from England. By 1832 it sold less than £100,000 worth and bought more than £400,000 worth. From about 1830, India bought more cotton cloth than it sold. India, which had sold cloth to the world, now bought British cloth, and it sold raw cotton to British mills.
Power mattered too. Much of India was ruled by the British East India Company, and British cotton cloth entered India at a tax of only 2½ percent. Earlier, Britain had taxed Indian cloth heavily: around 1813, Indian calicoes paid taxes of about 70 to 85 percent of their value to be sold in Britain. Historians still argue about how much each cause mattered: cheaper machine-made goods, the trade rules of the people in power, and, in India, troubles that had begun before the factories did, such as the breakup of the Mughal Empire and years of drought.
The Middle East felt the same pressure. In 1838 English cotton cloth sold in Egypt for less than cloth from Egypt's own new mills. (Who built those mills, and why, is Topic 5.6.)
Shipbuilding followed the same path. Bombay's teak ships were among the best wooden ships of their day. But by the middle of the 1800s navies were turning to ships of iron, driven by steam, and they came mostly from British shipyards and engine works. Bombay's age of teak warships came to an end.
Each card gathers the evidence for one part of the answer. The College Board asks how modes and locations of production changed over time, so the cards are the starting point, the change in places, the change in shares, and the continuity.
Evidence to sort: hand production at home and in workshops; Bairoch's estimates for about 1750 (China about a third, India about a quarter, Europe about a quarter, Britain under 2 percent); India's cloth sold across Asia, Africa and Europe; Indian teak ships.
Evidence to sort: the British laws (to 1824 and 1843); Slater at Pawtucket (1789 to 1793); Cockerill at Seraing (1817); the Nuremberg to Fürth railway (1835); Lowell (from the 1820s); Hughes at Yuzovka (1870s); the Osaka Spinning Company (1883). For three of them, name the carrier, then say the pattern.
Evidence to sort: Bairoch's estimates for 1860 and 1900 (Britain about a fifth by 1860; Europe and the United States over four-fifths by 1900; China about 6 percent, India under 2); steam-powered factories; cheaper machine-made cloth; India's cloth trade turning around by about 1830; the 2½ percent tax on British cloth entering India.
Evidence to sort: India's hand weaving, shrinking but surviving (about a million people living from it in one province in 1908); machine-spun thread on hand looms; Chinese farm families weaving at home; the handlooms of Aleppo and Damascus; the Bombay Dockyard and HMS Trincomalee (1817). For one, say what continued and what happened to its share.
In 1750 almost all the energy used in the world came from muscles, wood, wind and water. By 1900 about half of it came from coal. This chapter follows how machines unlocked that buried energy, what new things it let people make, and how railroads, steamships and the telegraph carried goods, people and news into the interiors of continents.
The College Board asks you to explain how technology shaped economic production between 1750 and 1900. That is a causation question, and the answer is a chain: each technology made the next one possible. Section 01 sets the starting point; sections 02 and 03 are the power; section 04 is the new methods; section 05 is the reach, and its two effects, trade and migration. Each section ends with a tool, a limit and a comparison you can use in an answer.
In 1750 almost all the energy used in the world came from things that grow, and from wind and water. Each had a limit.
In 1750 a farmer plowed with a horse or an ox, a family cooked and kept warm with wood, a ship crossed the ocean by sail, and a mill turned beside a river. Food gave energy to the muscles of people and animals. Wood gave fire. Wind and water turned some machines. All of these came, in the end, from the sun and the land: crops and forests had to grow, every year, to be used.
Each had a limit you could see. A horse gets tired and must be fed from land that could grow food for people. A forest takes decades to grow back. A sailing ship waits for the wind. A water wheel works only where a stream flows strongly, and turns slowly when the water runs low. Topic 5.3's example, Arkwright's mill at Cromford, ran on a water wheel fed by a brook and a mine drain.
There was another store of energy, underground. Coal and oil are each a fossil fuel: the remains of plants and tiny sea creatures, buried for millions of years, with energy stored inside them. Coal did not need land to grow this year. Britain already burned a great deal of it for heat (Topic 5.3). The trick was to turn its heat into motion.
The steam engine began as a pump for flooded coal mines. Watt made it use far less coal and turn wheels, so factories could run on coal instead of rivers.
As British miners dug deeper for coal, water flooded the mines. In 1712 Thomas Newcomen set up a steam engine near Dudley Castle, in the English Midlands, to pump it out. A fire boiled water into steam. The steam filled a cylinder under a piston; a spray of cold water turned the steam back into water, the air pressed the piston down, and a great wooden beam rocked to work the pump. It worked, but it burned a great deal of coal, because the cylinder was cooled and heated again on every stroke.
James Watt, an instrument maker at the University of Glasgow, was repairing a model Newcomen engine when he saw the waste. In 1765 he found the fix: cool the steam in a separate chamber, the separate condenser, so the cylinder could stay hot. He patented the idea in 1769. Watt's engines used less than a third of the coal of a Newcomen engine.
Then came the change that mattered most for factories. Watt's business partner, Matthew Boulton, wanted engines that could drive mill machinery. In the 1780s Boulton and Watt built engines that turned a wheel. A wheel can drive spinning machines, looms and hammers. A mill no longer had to sit beside a fast river: it could run on coal, wherever coal could be brought, and cotton mills crowded into towns such as Manchester.
Machines let people use far more energy than ever before: coal gave about half the world's energy by 1900. Oil and the internal combustion engine came next, but their big effects came later.
Steam engines needed coal, and coal mines needed steam engines to pump them dry, so each made the other grow. Britain mined about 65 million tons of coal in 1854 and about 225 million tons in 1900. By about 1900, coal supplied about half of all the energy used in the whole world; things that grow, such as wood, gave about the other half. The College Board calls this the fossil fuels revolution: it "greatly increased the energy available to human societies."
A person who lived through it said so. In 1865 the British economist William Stanley Jevons wrote that "with coal almost any feat is possible or easy; without it we are thrown back into the laborious poverty of early times." He was worried that Britain's cheap coal would not last forever. (His words are this lesson's Primary Source.)
In 1859 Edwin Drake drilled a well at Titusville, Pennsylvania, and struck oil. For the rest of the 1800s, most oil was refined into kerosene, a fuel for lamps.
A steam engine burns its fuel under a boiler, outside the engine. An internal combustion engine burns its fuel inside the engine itself, in the cylinder. In 1876 Nikolaus Otto built a four-stroke gas engine in Germany, and in 1886 Carl Benz patented a car driven by a small engine that burned a fuel made from oil.
After 1850, with so much energy to use, new methods made steel cheap, made chemicals in factories, sold electric power, and cut machine parts precisely enough to swap.
Steel is iron with a small, carefully measured amount of carbon. It is stronger and tougher than ordinary iron, but before the 1850s it was slow and costly to make in large amounts. In 1856 Henry Bessemer showed that blowing air through melted iron burned out the carbon and other impurities, and the burning kept the metal hot. The United States made about 69,000 tons of steel in 1870 and about 10 million tons in 1900; Britain went from about 215,000 tons to about 4.9 million. Steel became rails, bridges, ships and machines.
In 1856 an eighteen-year-old London chemistry student, William Perkin, made a purple dye, mauve, from chemicals that came from coal tar, a sticky leftover of coal. It was the first synthetic dye to sell well. German chemical companies such as BASF, founded in 1865, built laboratories whose job was to invent new dyes, and in 1897 BASF began selling indigo blue made in a factory instead of from a plant. By 1914 Germany made most of the world's dyes.
In 1882 Thomas Edison's Pearl Street Station in New York began selling electric power, lighting about 400 lamps on its first day. Electric motors could let each machine run on its own motor, instead of on belts from one big steam engine. But the change was slow: in 1899, electric motors gave less than 5 percent of the power in American factories, and it took about two more decades for them to give half. Factories had to be rebuilt to use them well.
Machine tools, such as lathes and milling machines, had begun to cut metal parts to exact sizes, so that one part fit any copy of the same machine; after 1850 the method spread widely. These are interchangeable parts. Standard screw threads, set early by Joseph Whitworth in Britain in 1841 and then by William Sellers in the United States in 1864, helped machines with interchangeable parts, "from typewriters to locomotives," as the American Society of Mechanical Engineers puts it, spread.
Railroads, steamships and the telegraph reached the interiors of continents and joined distant markets, which led to more trade and more migration.
Before railroads, heavy goods moved cheaply only by water, so the middle of a continent, far from rivers and the sea, was hard to reach. The Liverpool and Manchester Railway, opened in England in 1830, was the world's first railway between two cities, with trains pulled by steam locomotives. Railways spread fast: Russia had 27 kilometers of railway in 1840 and more than 53,000 in 1900; Germany went from 469 kilometers in 1840 to more than 51,000 in 1900.
India's first passenger train ran from Bombay to Thane in 1853. The first railroad across the United States was finished at Promontory Summit, Utah, in 1869. Russia began the Trans-Siberian Railway in 1891, and by 1904 trains could cross to the Pacific Ocean. A railroad could reach farms, mines and towns where no river or canal went.
Under sail, emigrants from Norway took about 53 days on average for the whole trip to America. By steamship, the Atlantic crossing from England took about 12 days in the 1860s, and the fastest ships of the 1870s crossed in about 7 or 8 days. The Suez Canal, opened in Egypt in 1869, cut the voyage from Europe to Asia; it was of little use to sailing ships, because the winds of the Red Sea were hard to sail against, so it mostly served steamships. Steamboats also pushed up rivers into the interior of continents: in 1854 the steamer Pleiad went far up the Niger and Benue rivers in West Africa, and none of its crew died, because they took quinine, a medicine against malaria. What European empires did with this reach is Unit 6.
A telegraph sends messages as pulses of electricity along a wire. In 1844 Samuel Morse sent "What hath God wrought?" from Washington to Baltimore. A cable under the Atlantic worked only a few weeks in 1858; from 1866 cables carried messages across it without a lasting break, and in 1870 another undersea cable, through the Red Sea, reached Bombay. A message that once traveled as fast as a ship could now travel in minutes, so merchants could know prices in distant markets within a day.
Cheaper, faster transport and fast news joined markets. In 1870 wheat cost 57.6 percent more in Liverpool, England, than in Chicago. By 1913 the gap was only 15.6 percent. Wheat grown in the middle of North America, carried by train to the coast and by steamship across the ocean, fed workers in Britain.
Trains and ships carried people, too. Migration means people moving to live in a new place. About 55 million Europeans moved to the Americas and Australia between 1850 and 1914. Between 1846 and 1940, more than 29 million Indians and more than 19 million Chinese moved to Southeast Asia and the lands around the Indian Ocean, and tens of millions of Chinese and Russians moved into Manchuria, Siberia and Central Asia. Steamships and railways made these journeys faster and cheaper. Why people moved, and what they found, is Unit 6.
Each card gathers the evidence for one link of the chain. The College Board asks how technology shaped economic production over time, so the cards follow the causes in order: power, new methods, reach, and its effects.
Evidence to sort: energy from muscles, wood, wind and water before 1750; Newcomen's mine pump (1712); Watt's separate condenser (1765, patented 1769), using under a third of the coal; rotary engines (1780s) and mills in towns; Drake's oil well (1859); Otto (1876) and Benz (1886).
Evidence to sort: Britain's coal, about 65 million tons (1854) and about 225 million (1900); coal about half the world's energy by about 1900; Jevons (1865): "with coal almost any feat is possible or easy"; 8,000 cars in the United States in 1900.
Evidence to sort: the Bessemer process (1856) and US steel (about 69,000 tons in 1870, about 10 million in 1900); Perkin's mauve (1856), BASF (1865) and factory indigo (1897); Pearl Street (1882) and motors under 5 percent of US factory power (1899); interchangeable parts and standard screw threads (1841, 1864).
Evidence to sort: the Liverpool and Manchester Railway (1830); Russia's railways (27 km in 1840, over 53,000 in 1900); Promontory Summit (1869); the Trans-Siberian (1891 to 1904); sail from Norway about 53 days, steam from England about 12 (1860s), the fastest 7 or 8 (1870s); Suez (1869); the Pleiad (1854); Morse (1844), the Atlantic cable (1866), Bombay (1870); the wheat price gap (57.6 percent in 1870, 15.6 in 1913); 55 million Europeans (1850 to 1914); over 29 million Indians and 19 million Chinese (1846 to 1940). For one, explain the link from the technology to the effect.
In Britain and the United States, private owners built the first factories. A few governments did not wait. This chapter follows two of them, Egypt under Muhammad Ali and Japan in the Meiji era: why each government built industry itself, how it paid for it, and why Japan's industry lasted while most of Egypt's factories closed.
The College Board asks you to explain the causes and effects of the economic strategies of different states. That is a causation question, and it comes with a comparison: two states, the same strategy, different results. Section 01 says why any government would build industry; sections 02 and 03 follow Egypt; sections 04 and 05 follow Japan. Build a chain for each with the same four links, the threat, the decision, the strategy and the result, then use the closing section to compare them.
Most early factories were built by private owners. A small number of governments built industry themselves, wanting armies to match stronger powers.
In Britain, Richard Arkwright and his partners paid for the mill at Cromford (Topic 5.3). In the United States, Boston merchants paid for the big cotton mills at Lowell (Topic 5.4). Governments helped in other ways, with patents, roads and taxes on foreign goods, but private owners built and owned the factories.
A small number of governments did something different. They planned factories, paid for them, owned them and protected them. This is state-sponsored industry, and the College Board names it as the exception: "a small number of states and governments promoted their own state-sponsored visions of industrialization."
By the early 1800s the countries with factories, steam engines and new weapons were becoming the strongest in the world. A ruler watching them could see two dangers: a country without industry could be beaten in war, or forced to sign treaties it did not want. Waiting for merchants to build factories might take too long. So a few rulers decided to build industry themselves, to make their states strong.
Muhammad Ali, Egypt's Ottoman governor, used the state's control of farming and cotton to pay for factories, and the factories supplied his army.
In 1798 a French army under Napoleon invaded Egypt and easily defeated its rulers, the Mamluks, a class of soldier-lords. The French left in 1801. Among the Ottoman troops sent to take Egypt back was Muhammad Ali, an officer from an Albanian family. In 1805 the Ottomans named him governor of Egypt, and by 1811, after his men killed the Mamluk leaders in the Cairo Citadel, he ruled alone.
Egypt was a province of the Ottoman Empire, and Muhammad Ali was the sultan's governor. Napoleon's victory had shown what a modern European army could do. Muhammad Ali wanted Egypt strong enough that he, and his family after him, could hold it, even against the sultan. Strength meant an army, and an army needed guns, uniforms and ships.
His government took control of Egypt's farming. It told peasants what crops to plant, bought the crops at low prices, and sold them abroad at higher ones. When there is only one allowed buyer or seller, that is a monopoly. A new crop, long-staple cotton, first grown for sale in 1820, earned a great deal of money.
With that money, from the late 1810s, the government built factories: cotton mills, and works for weapons, sugar and other goods. It bought machines in Europe and hired European experts to run them. By the early 1830s about 30 cotton mills employed about 30,000 workers, many of them making cloth and uniforms for the army. To protect the mills, Muhammad Ali kept cheap British cloth out of Egypt.
The workers did not choose these jobs. They were drafted, the way Egyptian peasants had long been made to dig canals and repair dams. From 1822 peasants were drafted into the army too. Forcing people to serve in the army is conscription. The army reached about 130,000 soldiers by the early 1830s. The historian Khaled Fahmy writes that Muhammad Ali's schools, factories and hospitals "were all founded to serve it." In the 1820s Muhammad Ali also sent Egyptian students to Europe to learn its sciences.
The army won wars until European powers stopped it. Then, with the army cut, the monopolies ended, almost no coal and drafted workers, most of the factories failed.
For a while the strategy did what Muhammad Ali wanted. In 1831 his army, led by his son Ibrahim, invaded Syria, and it beat the sultan's own armies more than once.
Britain, Austria, Russia and Prussia did not want a strong Egypt breaking the Ottoman Empire apart. In 1840 they sided with the sultan, and British warships and Ottoman troops drove Ibrahim out of Syria. In 1841 the sultan made the governorship of Egypt hereditary in Muhammad Ali's family, passing to its eldest male, but Egypt had to give up its conquests except Sudan. The sultan's decree said: "In time of peace, 18,000 men will suffice." Egypt also had to accept a trade treaty that Britain had signed with the Ottoman sultan in 1838, which ended Muhammad Ali's monopolies and opened Egypt to cheap foreign goods.
The factories had problems of their own, too. Egypt had almost no coal, so many machines were turned by animals instead of steam engines. The drafted workers resisted the work, and the managers had little experience. By the mid-1840s, about a decade after their peak in the early 1830s, most of the new factories had failed. Egypt went on growing more and more cotton, almost all of it sold abroad, much of it to the mills of Britain. What that led to is Unit 6.
American and European warships and unequal treaties pushed Japan's new Meiji government to reform the country before it built industry.
In 1853 an American naval officer, Commodore Matthew Perry, sailed warships into Edo Bay, near today's Tokyo, and demanded that Japan open its ports to trade. Japan had no navy that could stop him. Treaties in 1854 and 1858 opened Japanese ports to Americans and Europeans, let foreigners accused of crimes in Japan be tried in their own countries' courts, and took away Japan's control over its own trade. A tariff agreement of 1866 held Japan's taxes on most imports to about 5 percent, and Japan did not win back full control of them until 1911. A treaty forced on a weaker country that gives the stronger side rights it does not give back is an unequal treaty.
Some samurai blamed the shogun, the military ruler who governed Japan in the emperor's name, for giving in. In 1868 a group of young samurai overthrew him and governed in the name of the fifteen-year-old emperor, Meiji. This is the Meiji Restoration. In April 1868 the new government issued the Charter Oath, which promised: "Knowledge shall be sought throughout the world so as to strengthen the foundations of imperial rule." The government's slogan was "Rich country, strong army."
The Meiji leaders changed Japan itself. In 1871 they abolished the domains of the old lords and made one central state. The samurai lost their privileges, and men of every class were drafted into a national army. A national school system began in 1872. A new land tax, paid in money instead of rice, gave the government money to spend. From 1871 to 1873 a group of leaders, the Iwakura Mission, toured the United States and Europe to study how they worked.
Japan's government built railways, mills and shipyards, then sold most of them to private companies, and the strength it built made Japan a regional power.
The government built Japan's first railway, from Tokyo to Yokohama, which opened in 1872 with British engineers. In the same year it opened the Tomioka Silk Mill, with French machines and a French engineer, Paul Brunat, to teach Japanese workers, mostly young women, to reel silk by machine, so the method could spread to other mills. It built telegraph lines, shipyards, mines, and factories for weapons and for goods such as cement, glass and cloth.
Farmers paid for much of this through the land tax. Some samurai rebelled against losing their place, and in 1877 the new army of drafted commoners crushed the last great revolt.
Running so many businesses cost more than the government could afford. In 1880 it decided to sell most of them to private investors. Business families such as Mitsui and Mitsubishi bought them and grew into huge business groups called zaibatsu: Mitsubishi bought the Nagasaki shipyard in 1887, and Mitsui took over the Miike coal mine, the country's largest, in 1889. Private companies such as the Osaka Spinning Company (Topic 5.4) built more. The state started key industries; private companies carried them on and built much more.
To win back its own courts, Japan rewrote its laws on French and German models, and in July 1894 Britain agreed to end the foreign courts in Japan from 1899, so that foreigners there would be tried by Japanese law, and other countries followed; Japan won back full control of its tariffs only in 1911. Weeks later, in 1894 and 1895, Japan fought China over Korea and won. In the Treaty of Shimonoseki, China gave up its claim over Korea, gave the island of Taiwan to Japan, and agreed to pay an indemnity of 200 million taels of silver (a tael is a Chinese measure of silver). Within a week, Russia, Germany and France demanded that Japan give back one more piece of land it had won, and Japan gave in, which angered Japan's leaders. Japan, forced to open its ports forty years before, was now a regional power, with a colony of its own. What empires did with that power is Unit 6.
Each card gathers the evidence for one part of the answer. The College Board asks for the causes and effects of the economic strategies of different states, and its skill for this topic is finding a pattern, so the cards give each state's chain and then compare them.

Industry needed more money than any partnership could raise, and the money would not come while an investor could lose his house over a company he did not manage. The nineteenth century solved that, brilliantly, with a set of legal and financial instruments. Every one of them works by moving risk somewhere else, and this chapter follows where it went, from a shareholder’s balance sheet to an Egyptian tax collector.
Sections 01 and 02 are the institutions the success criteria ask you to define, each written with the mechanism rather than the definition. Section 03 is free trade as a policy rather than a doctrine. Section 04 is economic imperialism, which is the part that makes this topic matter for Unit 6.
The single most consequential financial innovation of the century is a legal rule about how much an investor can lose. Get the counterfactual right, what an investor faced before it, and the entire structure of modern industry follows from one change.
Under a partnership, and under most company forms before mid-century, liability was unlimited. If the business failed owing money, creditors could pursue the personal assets of every partner or shareholder: house, savings, everything. One investor could be made to pay the whole debt if the others had nothing.
Follow the consequence. If putting a hundred pounds into a railway could cost you ten thousand, then you invest only in businesses you can watch personally, run by people you know, in a trade you understand. Capital stays local, concentrated and cautious, and the total pool available to industry is a small fraction of the nation's savings. Meanwhile the Topic 5.5 chapter's railways, steel works and telegraph networks needed sums no group of mutually acquainted merchants could raise.
Limited liability reverses it: a shareholder's exposure is capped at the amount invested, and the company is a separate legal person that owes its own debts. Now a schoolteacher can put fifty pounds into a railway in a county she has never visited, because the worst case is losing fifty pounds. Multiply that by a whole propertied and salaried population and you have a capital market.
The legislative sequence in Britain is worth knowing precisely, because the success criteria name the endpoint. The Joint Stock Companies Act of 1844 allowed incorporation by simple registration rather than by an individual act of Parliament or a royal charter, which had been the old route and had kept incorporation a privilege. The Limited Liability Act of 1855 introduced the cap. And the Companies Act of 1862 consolidated the law into the modern form, general, cheap and available to anyone, which is why it is the turning point.
Nothing here removes risk; it relocates it. If a shareholder cannot be pursued, then a creditor who is not paid, a supplier left with unpaid invoices, a worker owed wages, absorbs the loss instead. That is precisely what contemporaries objected to, and the objection was strong enough to delay the reform for decades: critics argued it would license reckless speculation, encourage fraud and let men trade with other people's money while risking none of their own.
The compensating device was disclosure. Registration, published accounts, a register of directors and, over time, audit requirements are the price of the privilege: the public cannot pursue your assets, so the public gets to see your books. That trade, limited exposure in exchange for transparency, is still the basis of company law.
And a company is also a perpetual person, which matters as much as the liability cap. A partnership dissolves when a partner dies or withdraws; a company continues, holds property, sues and is sued in its own name, and can therefore commit to a forty-year project. The Topic 4.4 chapter's chartered companies had some of this by special grant; what changes in 1862 is that it becomes available to anybody who fills in a form.
Two institutions turned scattered savings into industrial plant. A stock exchange made a long-term investment sellable at short notice, and an investment bank decided which enterprises deserved the money, which made a handful of banking houses among the most powerful actors of the century.
A stock exchange is an organized market where shares and bonds are bought and sold. Its function is liquidity, and liquidity is the point most students miss. A railway takes five years to build and forty to pay off, but an investor may need his money next year for a daughter's dowry or a bad harvest. Without a resale market he must either commit for forty years or not invest; with one, he can sell his shares to somebody else tomorrow while the railway keeps the capital. The exchange therefore converts long-term illiquid projects into holdings people are willing to make, without the project losing its funding.
It also produces a continuous public price, which is a judgment on an enterprise's prospects that can be read by anyone, and which allows borrowing against securities as collateral. And it produces speculation and panics, since a market that prices expectations will sometimes price them wrongly and all at once: the railway manias of the 1840s, the crash of 1873 and the recurring panics of the century are the same institution working and failing.
An investment bank does not principally take deposits and lend; it underwrites. It agrees to buy an issue of shares or bonds from a company or a government, and then sells them to investors, taking the difference and carrying the risk of failing to place them. Doing that requires the one asset that cannot be bought quickly, which is the trust of investors, so a house whose name on a prospectus was taken as a guarantee of soundness could place an issue that an unknown promoter could not.
The success criteria name three and each illustrates a different role. The Rothschilds, operating across London, Paris, Frankfurt, Vienna and Naples, were the great sovereign lenders of the century, financing governments and wars and, through the family network, moving information and money across borders faster than states could. Deutsche Bank, founded in 1870, exemplifies the German model of a universal bank that took equity stakes in industrial firms, sat on their boards and coordinated whole sectors, which is a large part of how the state-led industrialization of Topic 5.4 was financed. The House of Morgan in the United States financed and then reorganized railroads and industries, imposing consolidation on chaotic markets, and in the panic of 1907 J. P. Morgan personally organized the rescue of the American banking system, because there was no central bank to do it, which is a substantial part of why the Federal Reserve was created in 1913.
Note what that concentration means. A small number of houses decided which railways, mines and steel works were built and which governments could borrow, and they did so on commercial judgment answerable to nobody. That is the fact behind the political anxiety about financial power in the later century, and it is also the mechanism section 04 depends on.
Britain adopted free trade at the exact moment it had the world’s cheapest manufactures, and other countries adopted tariffs at the exact moment they did not. That is not hypocrisy on anyone’s part; it is what the theory predicts, and saying so is the difference between describing the doctrine and understanding it.
David Ricardo set out comparative advantage in 1817, and it is one of the genuinely counterintuitive results in economics, so it is worth stating carefully. Even if one country produces everything more efficiently than another, both gain by specializing in what they produce relatively best and trading. His example was English cloth and Portuguese wine. The insight is that what matters is opportunity cost, what you give up to make a thing, rather than absolute efficiency.
Now note what it does not say. It says nothing about which specialization you end up with, and it treats that as given rather than as something policy creates. If a country's comparative advantage is in raw cotton because another country's policy destroyed its weaving, as the Topic 5.4 chapter describes for India, then specializing according to comparative advantage locks in that position. Industrial goods and primary products also behave differently over time, since manufacturing generates skills, machinery and further industries while a mine generates a mine. That is the critique the Topic 5.4 chapter's protectionists made and it is the standard argument for infant-industry tariffs.
The Corn Laws were tariffs on imported grain, kept high after 1815 to protect landowners' rents by keeping domestic grain prices up. The fight over them was a class fight in plain view. Manufacturers wanted repeal, because cheap bread means workers can live on lower wages and because countries that sold Britain grain would buy British cloth. Landowners wanted them kept. The Anti-Corn Law League, led by Cobden and Bright, ran what was effectively the first modern political campaign, with mass meetings, a periodical press and organized voter registration.
Repeal came in 1846, pushed through by Peel against most of his own party, with the Irish famine as the immediate occasion, and it split the Conservative Party. It marks the moment industrial interests decisively outweighed landed ones in British policy, and it committed Britain to free trade for the rest of the century.
The gold standard is the other half of the international system. Under it a currency is defined as a fixed weight of gold and is convertible into it, so exchange rates between countries on the standard are effectively fixed. Britain was on gold from the early nineteenth century and most major economies joined by the 1870s. Its advantage is certainty: a merchant or an investor lending abroad for thirty years knows what he will be repaid in, which is exactly what makes large-scale international investment possible, and it is therefore a precondition for section 04.
Its cost is that a government gives up control of its own money. If gold flows out, the money supply must contract, which means falling prices and wages and rising unemployment, and the government cannot expand credit to relieve it without breaking convertibility. So the adjustment falls on wage earners rather than on the exchange rate. That is the risk transfer this chapter is about, applied to a whole economy, and it is why farmers and workers in debt campaigned against gold, most famously in the United States in the 1890s.
A state does not have to be annexed to be governed. If a foreign body collects its taxes, foreign treaties set its tariffs and foreign courts try foreigners inside it, it has lost the powers that make sovereignty operative, and the instrument was a loan rather than an army.
The sequence is the same in every case and is worth learning as a sequence. A government borrows on European capital markets, usually for railways, ports, public works or a war. Because it is judged a risky borrower, the terms are hard: high interest, and bonds issued at a discount, so a state that owes a hundred may have received seventy. Servicing the debt requires foreign currency, which requires exports, which pushes the economy further toward primary products. When revenue falls short, it borrows again to service the first loan. At default, bondholders press their own governments, and the settlement is not forgiveness but control of the revenue: a foreign commission takes designated taxes at source to pay the creditors first.
Egypt is the case that runs the whole sequence. The Topic 5.4 chapter leaves it stripped of its industry by the Treaty of Balta Liman. It then borrowed enormously under Ismail for the Suez Canal, railways and public works, defaulted in the 1870s, sold its Suez shares to the British government, accepted an Anglo-French Dual Control over its finances, and, when a nationalist movement objected to foreign management of the country's money, was invaded and occupied by Britain in 1882. Debt to occupation in a generation.
The Ottoman empire supplies the purest institutional form. After default in 1875, the Ottoman Public Debt Administration was established in 1881: a body controlled by European bondholders' representatives, with its own staff of thousands, which collected specified Ottoman revenues, the salt and tobacco monopolies, stamp duties, silk tithes and others, directly, and applied them to the debt before the Ottoman treasury saw them. A sovereign empire with its own army, sultan and law had a foreign agency inside it collecting its taxes, and it lasted until the empire did.
Latin America is the diffuse version. British and later American capital financed railways, ports, utilities and government borrowing; the railways were laid to move exports to the coast rather than to integrate an internal market; debt service required export earnings; and when governments defaulted, the pressure ranged from gunboats to the American practice, in the Caribbean and Central America in the early twentieth century, of taking over customs houses directly. No annexation, and comprehensive influence over what these economies produced.
China is the treaty-port version. After the Opium Wars, a series of treaties from 1842 opened ports to foreign residence and trade, capped Chinese tariffs at a low fixed rate, granted extraterritoriality so foreigners were tried under their own consuls rather than Chinese law, and added indemnities that had to be borrowed to pay. From 1854 the Chinese Maritime Customs Service, which collected the tariff, was run by foreign inspectors-general. China was never colonized and was not, in the relevant respects, in control of its own commerce.
Be exact, because this argument is easy to overstate. These states retained their flags, their rulers, their armies and their internal administration, and in Egypt's case that ended anyway. What they lost was a specific and identifiable set of powers: the tariff, which Topic 5.4 shows is the instrument of industrialization; jurisdiction over foreigners on their own soil; and the disposal of their own tax revenue. Those three are what a state uses to direct its economy, so losing them means the economy is directed elsewhere.
And name the local decisions too, or the account becomes one in which things are done to passive states. Ismail chose to borrow at ruinous rates for prestige projects. Ottoman and Latin American governments borrowed to fund wars, courts and patronage as well as infrastructure. Local elites frequently profited from the arrangement and defended it. Structure and decision are both in the record, and a good answer has both.
Each card is a full argument: the claim, the specific evidence, and the reason. The first states a mechanism by giving its counterfactual, which is the technique the whole chapter uses.
Before it, an investor in a failed business could be pursued for its whole debt, house and savings included, so people only funded ventures they could personally supervise and capital stayed local and cautious. Capping exposure at the sum invested lets a saver put fifty pounds into a railway in a county she has never seen, because fifty pounds is the most she can lose, and multiplying that across a whole propertied population creates a capital market able to fund railways, steel and telegraphs. Britain got there in stages: registration without a charter in 1844, the liability cap in 1855, and the Companies Act of 1862 making cheap general incorporation available to anyone. The risk did not vanish; it moved to unpaid creditors, suppliers and workers, which is what disclosure requirements were extracted to offset.
Ricardo showed in 1817 that both parties gain by specializing where their opportunity cost is lowest, even when one produces everything more efficiently. But the theory takes the specialization as given, and open markets favor whoever is already cheapest, so the doctrine was rational for Britain and ruinous for a late industrializer. The Corn Laws fell in 1846 because manufacturers wanted cheap bread and export markets while landowners wanted rents, and Peel split his party to repeal them. The proof that position drives doctrine is that states switch sides: Britain was protectionist under mercantilism while catching up, the United States kept high tariffs throughout its industrialization, and Germany protected iron and steel from 1879.
Defining a currency as a fixed weight of gold makes exchange rates between participating countries effectively fixed, which is what lets an investor lend abroad for thirty years knowing what he will be repaid in, and that certainty is the precondition for the enormous international investment of the period. The cost is that a government gives up control of its money supply: if gold flows out, credit must contract, so prices and wages fall and unemployment rises, and the state cannot relieve it without breaking convertibility. The adjustment therefore falls on wage earners and debtors rather than on the exchange rate, which is why indebted farmers and workers campaigned against gold, most visibly in the United States in the 1890s.
Egypt borrowed heavily for the Suez Canal and public works, defaulted in the 1870s, sold its canal shares, accepted Anglo-French Dual Control of its finances, and was occupied by Britain in 1882 when a nationalist movement objected. The Ottoman empire defaulted in 1875 and from 1881 the Ottoman Public Debt Administration, run by European bondholders’ representatives with thousands of staff, collected salt, tobacco, stamp and silk revenues directly, before the treasury. China after 1842 was capped at a low fixed tariff by treaty, granted extraterritoriality so foreigners answered to their own consuls, and had its Maritime Customs Service run by foreign inspectors from 1854. None was annexed, and each had lost the powers a state uses to direct its own economy.
For the first half of the century, workers who agreed among themselves to ask for more money were committing a crime. Everything about how labor organized, what it demanded and how violently it was met follows from that starting point. This chapter is the law, the strikes, why Britain got a workers’ party and America did not, and the other movements that grew out of the same dislocation, including the one that connected a Lancashire mill to a Mississippi plantation.
Section 01 is the legal frame, and it explains the tactics in every section after it. Section 02 is the three American strikes the success criteria name. Section 03 is the comparative question they pose. Section 04 is abolition and the other reform movements, which share a cause with the labor movement even though they look unrelated.
Start every answer about nineteenth-century labor here. An individual worker was free to negotiate and had no power; workers acting together had power and were breaking the law. That asymmetry is not incidental to the story, it is the story.
The Combination Acts of 1799 and 1800 made it a criminal offense for workers to combine to raise wages or shorten hours, with summary conviction before magistrates who were frequently employers themselves. They were passed during the war with revolutionary France, when any organization of working men was read as potential sedition, and they sat alongside older statutes and the common law.
The logic offered was consistency with freedom of contract: a wage is a contract between an employer and an individual worker, and a combination interferes with that individual's freedom to make his own bargain. In practice the effect was to leave one party to that bargain able to wait and the other unable to eat, which is why the doctrine was defended most vigorously by people who never had to sell a day of labor.
Repeal came in 1824 and, after a wave of strikes, was narrowed in 1825 so that unions could exist but almost any effective action, picketing, persuasion, obstruction, remained prosecutable as intimidation or as restraint of trade. Legal existence without lawful action is the position British unions occupied for fifty years. The Tolpuddle Martyrs, agricultural laborers transported to Australia in 1834 for administering an unlawful oath rather than for the union itself, is the case that shows how prosecutors worked around the repeal. Full protection came only with the legislation of 1871 and 1875, which legalized peaceful picketing and removed criminal conspiracy from trade disputes.
The American version was judge-made rather than statutory. Under the doctrine of criminal conspiracy, courts held that workers combining to raise wages were conspiring to injure trade, a line running from the Philadelphia cordwainers' cases early in the century. Commonwealth v. Hunt in Massachusetts in 1842 is the usual turning point, holding that a union was not unlawful in itself and that legality depended on its purposes and means, which opened a door and left judges holding the handle.
And the instrument that mattered most came later: the labor injunction. A federal judge could order a strike to stop, on the grounds that it obstructed interstate commerce or the mails or damaged property, and a worker who continued was then in contempt of court, punishable immediately without a jury. That is how the Pullman strike in section 02 was broken. The Sherman Antitrust Act of 1890, written against corporate combinations, was applied to labor unions as combinations in restraint of trade, which is one of the sharper ironies in the unit.
Now the consequence to carry into everything else. If organizing is criminal and there is no legal machinery for arbitration, the tactics available to workers are the ones that do not require legal standing: machine-breaking, as the Topic 5.3 chapter describes among the Luddites; friendly societies disguised as social clubs; petitions and mass movements such as Chartism; sudden unplanned strikes; and, where those failed, violence. Historians describing early labor as disorganized or riotous are frequently describing what the law had left available.
The three events the success criteria name form a sequence, and the sequence is about escalating state involvement: local violence, then a political prosecution, then federal troops and a court order. Each one also taught the labor movement a lesson about what was survivable.
In the depression following the panic of 1873, the Baltimore and Ohio cut wages for the third time, and workers at Martinsburg stopped the trains. It spread along the rail network with no central organization at all, to Baltimore, Pittsburgh, Chicago, St Louis and beyond, drawing in other workers and the unemployed, and in Pittsburgh a confrontation with militia left dozens dead and railroad property burned on a large scale.
State militias proved unreliable, since local men would not always fire on neighbors, so federal troops were used to reopen the lines, in some places diverted from Reconstruction duties in the South. Roughly a hundred people died nationally.
The significance is that this was the first strike in the United States to become a national event and to be suppressed as one. Employers and governments concluded they needed better instruments, and built them: state armories in cities, expanded militias, and closer coordination between companies and courts. Labor concluded that spontaneous mass action produced martyrs, which pushes the movement in the direction section 03 describes.
Haymarket. The eight-hour day was the great demand of the mid-1880s, and a general strike for it began on 1 May 1886. At a rally in Chicago's Haymarket Square on 4 May, called after police killed strikers at the McCormick works the previous day, someone threw a bomb at police; the officer killed by it and others who died in the ensuing shooting, along with civilian dead, produced a wave of public fear. Eight anarchists were tried, the identity of the bomb-thrower never established and the prosecution built substantially on their published views rather than on evidence of the act; four were hanged, one died in custody, and the survivors were later pardoned by Governor Altgeld, who stated publicly that the trial had been unfair.
The consequence, and it is the one the criteria point at: Haymarket allowed employers and the press to identify labor organizing with anarchism, bombs and foreigners, since most of the accused were German-born immigrants. The eight-hour movement collapsed, the Knights of Labor, which had grown to enormous size and had no connection to the bombing, was fatally damaged by association, and a lasting association between unionism and subversion entered American public argument. May Day is commemorated internationally because of Haymarket, which is a fact many Americans do not know about their own history.
Pullman. George Pullman built a company town outside Chicago where his workers rented his houses and bought from his shops. In the depression of 1893 he cut wages roughly a quarter and did not cut rents, which is the detail that made the grievance unanswerable. The workers struck, and the American Railway Union under Eugene Debs backed them with a boycott: its members would not handle trains with Pullman cars, which stopped rail traffic across much of the country.
The response is the section's point. The railroads attached mail cars to Pullman trains, so that stopping a train obstructed the United States mail. The federal government obtained an injunction under that theory and under the Sherman Act, President Cleveland sent federal troops over the objection of the governor of Illinois, the strike was broken, about thirty people were killed, and Debs was imprisoned for contempt. Debs went into prison a trade unionist and came out a socialist, and ran for president five times.
Two industrial societies with similar problems produced different labor movements: one that formed its own political party and one that decided politics was a trap. The reasons are structural, and giving four of them is how you answer the comparative question the success criteria pose.
The American Federation of Labor, founded in 1886 under Samuel Gompers, adopted what it called pure and simple unionism: organize skilled workers by craft, pursue wages, hours and conditions through collective bargaining with employers, build strike funds and benefit schemes, and stay out of party politics beyond rewarding friends and punishing enemies at the ballot box.
The reasoning was drawn from the wreckage in section 02. Broad, politically ambitious organizations such as the Knights of Labor had been destroyed; radicalism had been used to justify hanging men at Haymarket; and the courts had shown they would break any strike that looked like a challenge to the system. Organizing the skilled, who were hard to replace, around demands an employer could actually concede was a strategy for surviving in that environment, and it worked in its own terms. It also excluded most workers: the unskilled, immigrants, Black workers and women were largely outside the craft unions, which is a cost worth naming.
The sequence of the vote and industrialization. British working-class men were largely excluded from the franchise until 1867 and 1884, described in the Topic 5.6 chapter, so they spent decades organizing politically to obtain it, through Chartism and after, and arrived with a tradition of independent political action and a class identity built by exclusion. Most American white men had the vote well before industrialization, so they entered the industrial era already inside two existing parties, and the natural move was to work within them rather than to build a third.
Ethnic and racial division. The American workforce was continuously renewed by immigration from many countries, speaking different languages, in a society with legally enforced racial hierarchy. Employers used ethnic divisions deliberately in hiring and in strikebreaking, and many unions excluded Black workers and, in the West, campaigned for Chinese exclusion. A class identity is harder to build across those divisions, and Britain’s workforce, whatever its regional differences and its substantial Irish immigration, was not divided in the same way or to the same degree.
State violence and the courts. American strikes were broken by federal troops, state militias and private armies such as the Pinkertons, and by injunctions, more routinely and more lethally than British strikes were. That raises the cost of confrontation and rewards the AFL's narrower strategy, and it also meant American radicals were more likely to be imprisoned or deported than elected.
Mobility and the shape of the electoral system. Land in the West, high internal mobility and comparatively higher wages weakened the sense of a permanent proletarian condition, and first-past-the-post voting in single-member districts punishes a new party severely, since a third party can win a substantial share of the vote and almost no seats. Britain had the same electoral system and a working class concentrated in industrial constituencies where a party could actually win them.
The British outcome followed: the Trades Union Congress and socialist societies formed a Labour Representation Committee in 1900, which became the Labour Party in 1906, and the Taff Vale judgment of 1901, which made unions liable for damages caused by strikes, convinced many unions that they needed their own members in Parliament rather than sympathetic ones. In the United States, socialism reached a real but minority following under Debs and no labor party was established.
The other great movements of the century look unrelated to labor and share a cause with it. Each is a response to something industrialization created: a slave economy it made profitable, a city it filled faster than the city could cope, a workforce it needed literate, and a misery it produced and then blamed on drink.
The structural connection is the sharpest single fact in this unit and it should be written as a chain. Lancashire's mills, described in the Topic 5.3 chapter, needed raw cotton in enormous and growing quantities. The American South, after the cotton gin made short-staple cotton profitable to process, supplied a very large share of it, grown by enslaved people whose numbers rose across the period. So the most advanced industrial economy in the world ran on a raw material produced by slavery, and the enslaved population of the United States grew because industrial demand made the crop worth expanding. Industrial capitalism and Atlantic slavery were not sequential stages; they were contemporaneous and connected.
Abolitionists used exactly that. Consumer boycotts of slave-grown sugar and cotton put the connection on a household shopping list, and free-produce movements sold goods certified as slave-free. The argument was that a British worker's cloth and a British family's sweetener implicated them in a system they claimed to abhor, which turns a distant moral question into a domestic one, and it is the ancestor of every ethical consumption campaign since.
British abolition came in stages: the slave trade in 1807, then slavery in the empire by the act of 1833, effective from 1834 with an apprenticeship system that kept the formerly enslaved working for their former owners and was ended early, in 1838, under pressure. Two things are usually left out. First, the act compensated the enslavers, twenty million pounds, an enormous fraction of national expenditure, financed by a loan that was not fully repaid until the twenty-first century, and it compensated the enslaved with nothing. Second, and decisively, enslaved people forced the timing. The Baptist War in Jamaica over Christmas 1831 and into 1832, led by the deacon Samuel Sharpe and involving tens of thousands, began as a general strike for wages and became the largest rising in the British Caribbean; it was suppressed with hundreds killed in the fighting and hundreds executed afterward, including Sharpe. The scale of the reprisals, reported in Britain, persuaded Parliament that maintaining slavery would mean permanent war. Abolition was argued for in London and made unavoidable in Jamaica.
The Cotton Famine of 1861 to 1865 shows the dependency from the other end. The Union blockade cut off Southern cotton, Lancashire mills closed, and hundreds of thousands of workers were thrown into destitution. British industry responded by developing supply in India, Egypt and Brazil, permanently restructuring the global cotton trade, and Egyptian cotton is the crop that underwrote the borrowing in the Topic 5.7 chapter. And a considerable number of Lancashire workers, though not all, supported the Union and the blockade that was starving them, on antislavery grounds, which is one of the more striking pieces of evidence about how far the abolitionist argument had reached.
Public health. The crisis itself is the Topic 5.9 chapter's; the movement is here. Edwin Chadwick's Report on the Sanitary Condition of the Labouring Population of 1842 assembled statistical evidence that mortality tracked living conditions with a precision nobody could dismiss, and argued that disease cost the state money in lost labor and poor relief, which is the argument that moved Parliament. Chadwick was wrong about the mechanism, holding to miasma theory, that disease came from foul air, and the practical prescriptions, drainage, water supply and refuse removal, were right anyway. John Snow's investigation of the Broad Street pump in 1854 and later germ theory supplied the correct explanation. The Great Stink of 1858, when the Thames became unbearable to a Parliament sitting beside it, produced the money for Joseph Bazalgette's London sewer system, an engineering work on a scale that only industrial technology made possible. Industrialization caused the crisis and supplied the cure.
Education. Britain's Elementary Education Act of 1870, the Forster Act, created school boards to fill the gaps left by church schools, and compulsory attendance and the removal of fees followed within two decades. The motives are worth naming honestly and they were mixed: an economy needing workers who could read instructions and do arithmetic; a state that had just enfranchised urban working men in 1867 and, in a phrase of the period, had to educate its masters; competition with better-schooled Germany; and a genuine reforming belief in opportunity. It also completed the removal of children from the workforce that the Factory Acts had begun, since a child in school is a child not in a mill.
Temperance. The Woman's Christian Temperance Union, founded in 1874 under Frances Willard, is the case to know, and it is more interesting than its subject. Heavy drinking was a real feature of industrial life, and its consequences fell hardest on women who had no legal claim on a husband's wages and few independent earnings. The WCTU became the largest women's organization in the United States, and under the slogan of home protection it moved from alcohol into suffrage, labor conditions, prison reform and public health, so a campaign that appeared to accept women's domestic role became a training ground for a generation of women organizers and a route into politics that the Topic 5.6 chapter's franchise arguments had left closed.
Each card is a full argument: the claim, the specific evidence, and the reason. The first explains most of the rest of the chapter, so start there.
The Combination Acts of 1799 and 1800 criminalized workers agreeing to seek higher wages, and American courts reached the same result through criminal conspiracy doctrine, both justified by freedom of contract: a wage is an individual bargain and a combination interferes with it. Each party could equally walk away, and an employer could wait weeks while a worker could not miss a week’s food, so the symmetrical rule handed the outcome to whoever could hold out. The same doctrine also struck down protective legislation, as in Lochner in 1905. With combination criminal and no arbitration available, the tactics left were machine-breaking, disguised friendly societies, mass petitioning and sudden strikes, which is why early labor looks disorganized.
In 1877 wage cuts on the Baltimore and Ohio produced an unorganized strike that spread along the rail network, and federal troops reopened the lines after local militias proved unwilling to fire on neighbors, with about a hundred dead. In 1886 a bomb at Chicago’s Haymarket rally, thrower never identified, produced a trial built on the defendants’ published views; four were hanged and the survivors later pardoned by a governor who called the trial unfair, and the eight-hour movement and the Knights of Labor collapsed under the association with anarchism. In 1894 railroads attached mail cars to Pullman trains so that the boycott obstructed the mails, a federal injunction followed, troops broke the strike, and Debs went to prison for contempt and came out a socialist.
British working-class men were excluded from the franchise until 1867 and 1884, so they spent decades organizing politically to win it, through Chartism and after, arriving with an independent political tradition that produced the Labour Representation Committee in 1900 and the Labour Party in 1906, with the Taff Vale judgment of 1901 convincing unions they needed their own MPs. Most American white men held the vote before industrialization and entered the industrial era already inside two parties. Add continuous immigration and legal racial hierarchy, which employers used in hiring and strikebreaking; routine suppression by troops, militias, Pinkertons and injunctions; and first-past-the-post districts that punish a third party. The AFL’s pure and simple unionism was a rational response to that environment.
Lancashire needed raw cotton in growing quantities and the American South supplied it, grown by an enslaved population that expanded because industrial demand made the crop worth expanding, so industrial capitalism and Atlantic slavery were contemporaneous and connected rather than sequential. Abolitionists used that directly through boycotts of slave-grown cotton and sugar, turning a distant system into a household transaction. Britain abolished the trade in 1807 and slavery by the act of 1833, compensating enslavers twenty million pounds and the enslaved nothing, with apprenticeship ended early in 1838. And the Baptist War in Jamaica over Christmas 1831, led by Samuel Sharpe and suppressed with hundreds killed and hundreds executed, is what persuaded Parliament that keeping slavery meant permanent war.
Manchester grew twelvefold in two generations, into pipes, drains and streets laid out for a market town. This chapter is what that was like to live in: the two classes industrialization created and what separated them at the dinner table rather than in theory, why the same century sent one woman to a mill at five in the morning and told another that leaving the house was improper, and why the water killed people.
Section 01 is the two classes as lived positions rather than as the categories Topic 5.6 argues about. Section 02 answers the question the success criteria press hardest, why the same ideology produced opposite lives in different classes. Sections 03 and 04 are the city and the water, which is where three of the named challenges get their explanation.
The Topic 5.6 chapter defines the two classes by their relationship to capital, which is correct and abstract. Lived from the inside, the line was drawn by something simpler: whether your income was predictable, and whether you could stop working without your household collapsing within a fortnight.
The middle class ran from factory owners, merchants and bankers at the top through engineers, doctors, lawyers, managers, shopkeepers and, at the bottom edge, clerks and schoolteachers. What united a range that wide was the source of the income: business, qualification and salary rather than an inherited title or rents from land.
That is genuinely new and it is the point the success criteria want. In the societies of every earlier unit, the people at the top held their position by birth and by land, and status was largely fixed at birth. A cotton manufacturer richer than a duke, or a physician with no land at all and a professional income, did not fit that scheme, and the nineteenth century is partly the story of this class acquiring the political weight to match its money, which is what the Reform Act of 1832 in Topic 5.6 concedes.
Its markers were visible and deliberate: a house away from the works and eventually in a suburb reachable by railway, at least one domestic servant as the minimum sign of respectability, a parlor for receiving visitors, schooling for the children, church attendance, and a wife who did not earn. That last one is section 02, and it is the sharpest marker of all.
And a warning about the phrase. Middle class in nineteenth-century Britain does not mean the middle of the income distribution, which would be a well-paid manual worker. It means a position defined by the source of income and by a set of respectability markers, and a clerk earning less than a skilled engineer would count himself in it and the engineer out of it, which tells you the category is social as much as economic.
The working class sold labor for wages, in mills, mines, workshops, docks, building sites and, for the largest single group of women, other people's houses. The Topic 5.3 chapter has the hours and the danger; what belongs here is what the wage did and did not buy.
Insecurity is the defining feature, more than the level of the wage. Work was seasonal, trade was cyclical, and a downturn such as those of the 1840s put whole towns out of work at once. An injury ended earnings immediately, and the machine that caused it carried no liability. There was no sick pay and no pension, and after 1834 public relief was meant to run through the workhouse of Topic 5.6, deliberately made worse than the worst job. In practice most paupers went on being relieved in their own homes, because refusing outdoor relief to everyone would have cost more than the parishes could raise in a bad year, so what the New Poor Law reliably delivered was not the workhouse itself but the threat of it. So a household that was comfortable in a good year was destitute within weeks of a bad one, and this is why so much working-class organizing, described in Topic 5.8, went into friendly societies, burial clubs and mutual insurance rather than into politics.
Household economy followed from that. A working-class family needed multiple earners, which is why women and children worked, and the household budget went overwhelmingly on food, above all bread, with rent next, leaving nothing to absorb a shock. Diet was monotonous and often adulterated, since bread was bulked with alum and other additives before food regulation. Everyone in a family shared one or two rooms, and possessions could go to the pawnshop on Monday and be redeemed on payday.
And the class was internally graded in ways contemporaries took very seriously. A skilled engineer, printer or mule spinner in steady work, with a union and a friendly society, lived a life closer to a clerk's than to a casual dock laborer's, and that stratum, sometimes called the labor aristocracy, is where the unions of Topic 5.8 were built.
The nineteenth century held, loudly, that a woman’s place was the home. The same century employed enormous numbers of women in mills, mines and other people’s kitchens. Both are true because the doctrine described the lives of households that could afford it and was used to judge the households that could not.
Separate spheres held that men and women were suited by nature to different domains: the man to the public world of work, commerce and politics, the woman to the private world of household, children and moral guardianship. The home was described as a refuge from a competitive commercial world, and the woman was its keeper, which gave her genuine authority over household management, spending, the servants and the children's early education while removing her from anything outside the door.
Now the economics, which is what the success criteria are asking for when they demand the why. This arrangement requires a household that can live on one income. That is the whole explanation. A family that can survive on a man's earnings can withdraw a woman's from the market, and doing so becomes the visible proof that it can, which converts a non-earning wife into the single most legible marker of middle-class status. It is expensive, and being expensive is the point.
A working-class household could not afford it. It needed every earner, so women worked in textile mills, in workshops and the sweated trades, in agriculture at harvest, underground in mines until the ban of 1842, and above all in domestic service, which was the largest single occupation for women in Britain across the century. Married women often withdrew from full-time factory work when children arrived and took in laundry, lodgers, sewing or childminding instead, which is invisible in the census and was real income.
So the same ideology produced opposite lives, and produced a judgment on top of that. Working-class women were criticized for neglecting a domestic role their household economy made impossible, and the criticism came from reformers, clergy and inspectors who often sincerely wanted to help. Naming that double bind is a strong move in an essay: the doctrine did not merely fail to describe working-class life, it supplied the vocabulary in which working-class life was found wanting.
The costs to middle-class women were concrete. Girls' education emphasized accomplishments, music, drawing, French, over the classics and mathematics that qualified a boy for university and a profession. Professions were closed: medicine, law, the church, the universities, and admission came only late in the century and against organized resistance. Under coverture, described in Topic 5.1, a married woman's property and earnings were her husband's until the Acts of 1870 and 1882. Economic dependence was total, which made a bad marriage inescapable, since divorce was practically unavailable and custody went to fathers.
And what it built, which the flat version of this story leaves out. Domestic authority was real authority, over a household budget and a staff. Philanthropy, charity visiting, Sunday schools and moral reform were defined as extensions of the domestic sphere and were therefore permitted, and they took middle-class women into slums, workhouses and prisons, gave them organizational experience, and produced the campaigning networks that the Topic 5.8 chapter's temperance and abolition movements ran on. The WCTU's slogan of home protection is exactly this move: accept the sphere and argue that protecting the home requires acting outside it. That is how a doctrine of confinement generated a generation of organizers.
Children divide the same way and for the same reason. Middle-class childhood became a protected stage with schooling, toys and sentiment attached to it, which is affordable when a child does not need to earn. Working-class children worked, in mills and mines as Topic 5.3 describes, and then in street trades, workshops and domestic help, and their earnings were a necessary part of the household budget rather than pocket money. The compulsory schooling of Topic 5.8 changed that by making it illegal, which cost poor families income and was resented for that reason before it was welcomed.
The problems of the industrial city were not caused by the character of the people in it, which is what contemporaries mostly said. They were caused by a rate of growth that no existing infrastructure or government could absorb, and each named challenge follows from that arithmetic.
Manchester went from roughly 25,000 to about 300,000 between 1772 and 1850; Britain passed from a majority rural to a majority urban population across the same century, the first country in history to do so. Migration came from the countryside, pushed by enclosure and by agricultural change and pulled by wages, and from Ireland in enormous numbers after the famine of the 1840s.
Now take the challenges the success criteria name and derive each one, which is what they are asking for.
Housing shortage. Population grew far faster than dwellings could be built, so rents rose, and what got built was built to the cheapest specification the market would bear, since there were no building regulations to set a floor. Hence back-to-backs, houses sharing three walls with neighbors so that only one side has windows and no through ventilation is possible; hence courts and cellars, with families living below street level in rooms that flooded; hence overcrowding measured in families per room rather than rooms per family. Overcrowding is not a preference, it is what happens when the number of people divided by the number of rooms produces that answer.
Insufficient infrastructure. A town of 25,000 has pipes, drains, wells and streets sized for 25,000. Multiply the population by twelve and there is no mechanism by which the pipes multiply too, because water was supplied by private companies to customers who could pay, drainage was a parish matter, and the municipal government was a corporation designed for a market town, in some cases with no authority to levy for such works at all. The reformed municipal corporations from 1835 and the public health legislation from 1848 are the beginning of building a government capable of the problem, and they arrive decades after the problem.
Pollution and filth. The coal smoke is in Topic 5.5. On the ground it was human and animal waste: privies shared by dozens of households, cesspools under floors, middens in courts, horse dung in the streets in enormous daily volumes, slaughterhouses and tanneries among the dwellings, and no collection service. This is the immediate setting for section 04.
Crime, and how to handle the claim. Recorded crime rose, and so did the number of things counted as crime, the number of police counting them, and the population being counted, so the statistics are measuring several changes at once. What is solid is that a city of strangers works differently from a village where everyone is known, since anonymity weakens informal control, and that a population with no savings and no relief but the workhouse will produce theft in a downturn. The response was institutional: the Metropolitan Police from 1829 and forces elsewhere after, plus prisons built on new principles. Contemporaries mostly read urban crime as moral degeneration among the poor, and that reading is itself evidence about the observers, which is the sort of distinction worth drawing in an essay.
The success criteria ask specifically why overcrowded tenements without clean water or sewers produced cholera and typhoid, and the answer is a mechanism you can state in two sentences. Both diseases spread by the fecal-oral route, and a city with no sewers puts its waste into the water it drinks.
Cholera is caused by a bacterium ingested in contaminated water or food. It causes catastrophic diarrhea, and death follows from dehydration, sometimes within hours, which is why it terrified people in a way that endemic tuberculosis did not: a person could be well at breakfast and dead by evening. The infected material passes into the environment, and where sanitation is absent it reaches the water supply, which infects the next person. Typhoid works the same way, through contaminated water and food, more slowly.
Now put that mechanism in the city of section 03. Waste goes into cesspools and privies. Cesspools leak into the ground, and courts drain into ditches and streams. Water is drawn from shallow wells in the same ground, or piped by private companies from rivers into which the city's sewage flows, sometimes downstream of the outfall. Households share a standpipe running for a few hours a day, so water is stored in open vessels in crowded rooms. Every one of those steps closes the loop between what leaves a body and what enters the next one, and the density means one case reaches hundreds.
Then the perverse detail that makes this a good teaching case. Building proper sewers to flush waste out of the streets made the epidemics worse in the short term, because the sewers discharged into the Thames, and the Thames was where the water companies drew from. A sanitary improvement carried out under a wrong theory of disease moved the contamination from the street to the drinking supply, which is why the mechanism and not merely the effort is what has to be understood.
Britain had major cholera epidemics in 1831 to 1832, 1848 to 1849, 1853 to 1854 and 1866, with tens of thousands of deaths each time, and the disease had arrived from South Asia along the trade and troop routes of an expanding empire, which is a connection to Unit 6 worth noting: the same integration that moved cotton moved pathogens, exactly as the Topic 2.6 chapter describes for an earlier network.
The prevailing explanation was miasma theory, that disease arose from foul air given off by filth. It fitted the observation that disease was worst where the smell was worst, and it was wrong about the route while being right that filth was the problem, which is why sanitary reformers acting on it still did enormous good. The Topic 5.8 chapter has Chadwick, the reform movement and Bazalgette's sewers; what belongs here is how the mechanism itself was established.
John Snow argued that cholera was water-borne and demonstrated it in 1854 in Soho by mapping deaths against the pump they drew from, and, more powerfully, in a study comparing households in the same streets supplied by two different water companies, one drawing from a sewage-contaminated stretch of the Thames and one from further upstream, which found death rates several times higher among the first company's customers. That second study is the stronger evidence, because the households were otherwise similar in air, income and neighborhood, so the water was the only variable that differed. Snow did not persuade the profession immediately; germ theory, developed by Pasteur and Koch, who identified the cholera bacterium in 1883, supplied the explanation that made his result inevitable.
What actually ended the epidemics was engineering: intercepting sewers that carried waste far downstream, filtered water supplied under pressure, and eventually municipal ownership of the supply. Bazalgette's London system, funded after the Great Stink of 1858 made the river intolerable to Parliament itself, is the monument. Mortality in British cities improved substantially in the last third of the century, and clean water and sanitation are the largest identifiable reason.
Each card is a full argument: the claim, the specific evidence, and the reason. The second and third answer the two success criteria that ask you to explain why rather than to describe.
The middle class ran from factory owners and bankers through engineers, doctors and managers down to clerks and schoolteachers, united by income drawn from business, qualification or salary rather than inherited title or rent from land, which is a position the older order of birth and land had no category for. Its markers were deliberate and visible: a house away from the works, a servant, a parlor, schooling, and a wife who did not earn. Note that a clerk might earn less than a skilled engineer and count himself in it while placing the engineer out of it, which shows the category was social as much as economic. The working class sold labor for wages, and what defined its life was less the size of the wage than its insecurity, since injury or a downturn meant destitution within weeks and after 1834 relief was governed by a workhouse built to be worse than the worst job, held over applicants even where, as usually happened, they were relieved at home instead.
The doctrine assigned men the public world and women the home, and withdrawing a woman’s earnings requires a household able to live on one income, so a non-earning wife became the clearest visible proof that a family had reached that level. Working-class households needed every earner, so women worked in mills, workshops, agriculture, mines until the 1842 ban and above all in domestic service, the largest single female occupation of the century, and married women took in laundry, lodgers and sewing that the census never recorded. The same ideology therefore produced opposite lives and then supplied the vocabulary in which working-class women were criticized for neglecting a domestic role their household economy made impossible.
Manchester went from about 25,000 in 1772 to about 300,000 by 1850, and pipes, drains, streets and government do not multiply because people arrive. Housing shortage follows because dwellings cannot be built that fast, so rents rise and what gets built meets the cheapest specification a market with no building regulation will bear, which is what back-to-backs and inhabited cellars are. Infrastructure shortfall follows because water was sold privately to those who could pay, drainage was a parish matter, and the corporation was designed for a market town. Filth follows from privies shared by dozens of households with no collection service. And crime statistics rose alongside the number of police counting them, so read them as measuring several changes at once.
Cholera and typhoid pass from one person to the next through contaminated water, so a city storing waste in leaking cesspools and drawing water from the same ground, or from a river below its own sewage outfall, connects every household’s waste to every other household’s cup, and density turns one case into an epidemic. The proof is Snow’s South London study of 1854: competing companies had laid pipes house by house years earlier, so neighboring households alike in air, income and diet received water from different sources for no health-related reason, and when one company moved its intake upstream of the sewage and the other did not, mortality among the two sets of customers diverged enormously. Building sewers under miasma theory had first made things worse by discharging into the Thames the water companies drew from.
In 1750 most people on earth farmed, moved at the speed of a horse and lived under someone who inherited the right to rule them. By 1900 a third of that had changed completely, a third had changed its form and kept its shape, and a third had not moved at all. This chapter is how to tell which is which, and how to write a thesis that takes a position instead of listing both.
This chapter does not re-teach the unit. Section 01 is the changes in the form an essay needs them, each with a mechanism. Section 02 is the continuities with the reason each counts as one. Section 03 is the method for deciding, and section 04 is a full thesis written out with its own counterargument, which is what the third success criterion is asking for.
The success criteria ask you to name changes and tie each to a key concept, and tying means showing the causal link rather than filing the fact under a heading. Three will do more work than ten, if each one is written with the mechanism attached.
The change: production stopped being limited by muscle, water and wind and began running on stored fossil energy.
Why it matters, mechanically: every economy before this one had a ceiling set by how much work living things and moving water could do in a year, and that ceiling is why output per person had risen so slowly for so long. Coal removes it, because a seam represents millions of years of accumulated energy available all at once. That is the single fact under everything else in Unit 5: the factory of Topic 5.3, the railway and telegraph of Topic 5.5, the cities of Topic 5.9 and the military gap that opens in Unit 6 are all consequences of an energy source that does not run out at the end of the season.
Tie it: this is the industrial economy key concept in its strongest form, and the environmental key concept as well, since a species burning fossil carbon at scale begins here, as the Topic 5.5 chapter records.
The change: the typical relationship between a worker and the means of production inverted. Before, most people had access to some productive property, a strip of land, a workshop, a loom in the parlor; after, most people in industrial societies owned none and sold hours instead.
Why it matters, mechanically: as the Topic 5.6 chapter sets out, a person with no productive property has exactly one thing to withhold, which makes collective action the characteristic form of industrial politics and makes the legal treatment of combination, in Topic 5.8, the decisive question of the century. It also produced ideologies that had not existed before: socialism and Marxism are answers to a question that could not have been asked of a society of peasants and craftsmen.
Tie it: social structures and governance both, since this is the origin of class as the organizing political category and of the state's new responsibility for welfare, from the Factory Acts to Bismarck's pensions.
The change: the cost of moving goods and the time taken to move information both fell by orders of magnitude, through railways, steamships, the Suez Canal and the telegraph.
Why it matters, mechanically: the Topic 4.8 chapter argues that the world became connected in the sixteenth century in the sense that a closed circuit existed. This is different and it is worth stating as the difference: connection became cheap, which means ordinary bulk goods rather than luxuries, and it became fast, which means prices in Bombay and Liverpool move together in a day. That is what turns a network of trade into a single market, and it is why an Argentine harvest could lower a German farmer's income.
Tie it: economic systems and technology, and it is also the mechanism that made the imperialism of Unit 6 practicable, since an empire is only governable at the speed its orders travel.
A continuity is not a thing that failed to change. It is a structure that persists while its content changes completely, and saying which is the structure and which is the content is the whole of this part of the answer.
The continuity: a small group controlled most of the productive wealth and most of the political power, and a large majority worked for them with little of either.
Why it counts: compare a landlord and tenant in 1750 with a factory owner and worker in 1880. The names, the legal basis and the setting are entirely different, and the shape is the same: a propertied few, a working many, an enormous gap in wealth and security, and political institutions weighted toward the top. The Topic 5.6 chapter describes a new elite of capital displacing an elite of land, and displacing an elite is not the same as removing a hierarchy. That is the sentence a grader is looking for.
The honest complication, which strengthens the answer rather than weakening it: the terms did change in ways that mattered. Legal serfdom ended across Europe, Russia included in 1861; slavery was abolished across the Atlantic world; hereditary status gave way to a hierarchy that was formally open. So the correct claim is precise: hierarchy persisted as a structure and became economic and formally open rather than legal and closed, which is continuity of shape with change of mechanism.
The continuity of the rights struggle. The Topic 5.1 chapter identifies the move, holding a general principle to its own terms, and every campaign in this unit runs it: revolutionaries against monarchs, the enslaved against enslavers, Chartists and unionists against property qualifications and combination law, women against a franchise defended in universal language. The parties change constantly and the argument does not, which is exactly what a continuity is. And it is a continuity that continues past this unit, since the anticolonial movements of Units 6 and 8 use the identical move against the empires that taught it to them.
The continuity of most people's lives. This one is worth naming because it corrects the unit's center of gravity. In 1900, the great majority of people on earth still farmed, still lived in villages, and still worked with tools their grandparents would have recognized. Industrialization was concentrated in a handful of regions, for the reasons the Topic 5.4 chapter gives, and outside them the nineteenth century did not transform daily labor. The changes reached those regions in a different form, as demand for cotton, rubber, guano and grain, as railways built to the coast, and as debt, all of which reshaped economies without industrializing them.
Writing that continuity is one of the most reliable ways to demonstrate a global perspective rather than a European one, and it is defensible with the evidence already in this unit.
Most facts in this unit can be argued as continuity or as change, and a student who notices that usually panics. It is the opposite of a problem: it is the opening, because specifying which reading you mean and why is the analytical move the prompt is actually testing.
1. At what level? Slavery is the clearest case. At the level of the institution, abolition across the Atlantic world is an enormous change. At the level of coerced labor, indentured servitude, debt peonage, the Congo rubber system of Topic 5.5 and the mita's descendants continue, so the practice persists in new legal forms. Both are true, and the sentence that scores says which level it is pitched at.
2. For whom? A Lancashire mill worker, a Bengali handloom weaver, an American plantation laborer, a Japanese farmer under the land tax and a Congolese rubber tapper are all in this unit, and the extent of change is wildly different for each. A claim that names its population is stronger than a claim about "society."
3. Over what span? From 1750 to 1800, very little has happened outside a few British counties. From 1750 to 1900, the world economy is unrecognizable. Prompts carry dates and the dates are part of the question.
4. Compared with what? Change is a comparison and is meaningless without a baseline. Compared with the century before, the nineteenth is a transformation. Compared with the twentieth, its technologies look continuous with what preceded them. Say what your baseline is.
Take a single fact and watch the four questions produce four different defensible answers, which is what makes them a method rather than a checklist.
The fact: women entered factory work in large numbers.
At what level? At the level of whether women worked, this is continuity, and the Topic 5.9 chapter says so: women had always worked. At the level of where and on whose terms, it is a genuine change, since the workplace separated from the home for the first time.
For whom? For working-class women it meant wage work away from home. For middle-class women it meant the opposite, withdrawal from paid work as a marker of status. One economic change, two opposite outcomes, decided by what a household could afford.
Over what span? Across the whole century it is change, since married women's property rights, education and eventually the vote follow. Across the first fifty years it is mostly a change of setting without a change of position.
Compared with what? Compared with the household economy immediately before, the factory is a break. Compared with the position of women in the societies of Units 1 to 4, the fundamentals of legal subordination and domestic responsibility are strikingly persistent until very late in this period.
Four answers, all supportable, and none of them contradicts the others because each is a different question. Writing one of them explicitly, with the qualifier attached, is what an extent-of-change prompt rewards.
The success criteria ask for a defensible thesis that takes a position on the extent of change, supports both sides with specific evidence, and explains the reasoning. Here is one, written out, so you can see the shape rather than infer it.
Prompt: Evaluate the extent to which industrialization transformed societies in the period from 1750 to 1900.
A weak thesis: "Industrialization changed society a lot, but some things stayed the same." It takes no position, names nothing, and could preface an essay about any period in the course.
A defensible thesis: "Industrialization transformed how societies produced and where their people lived more completely than any change since agriculture, but it left the basic structure of social hierarchy intact, replacing an elite of land with an elite of capital while the majority continued to work for others with little property or political power, and outside a small number of industrializing regions it altered what the world's farmers grew and sold without changing that they farmed."
Notice what that sentence does. It takes a position, that the change was profound in one dimension and limited in another. It specifies the dimensions, production and settlement against social structure. It names its scope, distinguishing industrializing regions from everywhere else. And it gives the grader a map of the essay, because each clause is a paragraph.
The change side, with evidence. Britain passed from a majority rural to a majority urban society within a century, and Manchester grew from about 25,000 to about 300,000 between 1772 and 1850. Production moved from households working at their own pace to factories running on the clock, after Arkwright concentrated workers and machines at Cromford in 1771. Watt's rotary engine of 1781 and Bessemer's converter of 1856 removed the energy and materials ceilings, and the telegraph from 1844 separated the speed of information from the speed of transport for the first time in history. Entirely new political ideologies, socialism and Marxism, appeared to explain conditions that had not previously existed.
The continuity side, with evidence. A new elite displaced an old one rather than dissolving the hierarchy: the Reform Act of 1832 admitted the middle class to the political nation and left the working class outside, and Chartism was rejected. Wealth stayed concentrated at the top throughout, on the tax and probate evidence. Coerced labor persisted in new forms after abolition, in the Congo rubber system and in indenture and debt peonage. And in 1900 the great majority of the world's people still farmed, since industrialization reached a short list of regions and reached the rest as demand for raw materials, as railways built to the coast and as debt.
The reasoning, which is the part most answers omit. These two sides do not cancel, and the reason is that they describe different levels. Industrialization changed the means by which wealth was produced and the places where people lived, and it did so with a completeness that has few parallels. It did not change the relationship between those who own productive property and those who work it, and in the regions it did not industrialize it changed what was produced rather than how. A transformation of means with a persistence of relations is a coherent position, and it is why the nineteenth century produced both the greatest increase in output in history and the largest movements demanding that its benefits be shared.
Each card is a full argument: the claim, the specific evidence, and the reason. The last one is a complete thesis with its concession attached, which is the deliverable this topic is asking for.
Every economy in this course before the nineteenth century was limited to the work that muscle, water and wind could do in a year, which is why output per person had risen so slowly for so long. A coal seam is stored energy accumulated over geological time and spendable at whatever rate the machinery allows, so the constraint disappears. Everything else in Unit 5 sits downstream of that: the factory at Cromford in 1771, Watt’s rotary motion in 1781, Bessemer steel in 1856, railways, the telegraph, and cities that grew twelvefold in two generations. Note the contrast with Champa rice and the potato, which raised calories per acre and therefore the number of people supported; coal raised output per person, which is a change in kind rather than in scale.
Compare a landlord and tenant in 1750 with a factory owner and worker in 1880: the names, the legal basis and the setting are entirely different and the shape is identical, a propertied few, a working many, a large gap in wealth and security, and political institutions weighted to the top. The Reform Act of 1832 admitted the middle class to the political nation and left the working class outside, Chartism was rejected, and tax and probate evidence shows wealth concentrated at the top throughout. The honest qualification strengthens the claim: legal serfdom and slavery ended and status became formally open, so hierarchy persisted as a structure while its basis moved from birth and land to capital.
Women entering factory work reads as continuity at the level of whether women worked, since they always had, and as change at the level of where and on whose terms, since the workplace separated from the home. It meant wage work away from home for working-class women and withdrawal from paid work as a status marker for middle-class women, so the population named decides the answer. Across the whole century it is change, since property rights, education and the vote follow; across the first fifty years it is mostly a change of setting. And measured against the household economy immediately before it is a break, while measured against Units 1 to 4 the legal subordination is strikingly persistent. Four defensible answers, four different questions, and naming which one you mean is the analytical move.
Industrialization transformed how societies produced and where their people lived more completely than any change since agriculture, and left the basic structure of social hierarchy intact, replacing an elite of land with an elite of capital while the majority continued working for others with little property or power, and outside a small number of regions it altered what the world’s farmers grew and sold without changing that they farmed. The two halves do not cancel because they are pitched at different levels: the means of production and the places people lived changed almost completely, the relationship between owners and workers did not, and where industry never arrived the change was in the crop rather than the work. That is also why the same century produced the largest rise in output in history and the largest movements demanding it be shared.
