Revolutions

What this unit covers

The topics below follow the published World History course framework for Unit 5. This unit is worth 12–15% of the exam, so budget your time against that rather than against how long the unit takes to teach.

Every term in Unit 5

All 40 terms we publish for Revolutions, with definitions. Reading them through is the fastest way to find the ones you cannot define — then drill those in cram mode until you can produce them without the prompt.

Enlightenment

Application of reason to human affairs — natural rights, social contract, separation of powers — supplying the vocabulary of every revolution in this unit.

Factory system

Concentration of production in mechanized, power-driven workplaces under managerial discipline. Significance: replaced artisanal and cottage production, imposed clock time and wage dependence, drove urbanization, and generated the labor unions and socialist politics of the nineteenth century.

Social contract

Government legitimacy derives from the consent of the governed and may be withdrawn. Locke and Rousseau give the argument its revolutionary edge.

American Revolution

Colonial rebellion justified by natural rights and no taxation without representation. Its success made Enlightenment principles look practicable.

French Revolution

Overthrew monarchy and privilege in the name of liberty, equality and fraternity, then passed through terror to Napoleon — a pattern later revolutions repeated.

Declaration of the Rights of Man

Asserted universal rights while excluding women and, initially, the enslaved. Its own logic supplied the argument against those exclusions.

Haitian Revolution

The only successful large-scale slave revolt to found a state. Led by Toussaint Louverture, it terrified slaveholding societies everywhere.

Latin American independence

Creole elites led by Bolívar and San Martín broke from Spain, keeping the social hierarchy largely intact beneath the new republics.

Simón Bolívar

Led independence across northern South America and argued for federation, which fragmented into separate states after his death.

Nationalism

Loyalty to a people sharing language, culture or history. Unified Italy and Germany while pulling multi-ethnic empires apart.

Unification of Italy and Germany

Both achieved by war and diplomacy — Cavour and Garibaldi, then Bismarck's Realpolitik — creating powers that upset the European balance.

Industrial Revolution origins in Britain

Coal and iron, agricultural surplus, colonial markets, available capital, stable government and enclosure-driven labor supply combined there first.

Steam engine and its consequences

Freed industry from riverside water power, so factories could concentrate in cities, and powered railways and steamships that shrank distance.

Second Industrial Revolution

Steel, chemicals, electricity and the internal combustion engine from about 1870, shifting industrial leadership toward Germany and the United States.

Adam Smith and laissez-faire

Argued markets coordinate through self-interest better than state direction — the intellectual defense of industrial capitalism.

Karl Marx

Analyzed history as class struggle and predicted proletarian revolution against capitalism. Shaped labor movements and twentieth-century states.

Utopian socialism and labor unions

Owen's model communities and later unions sought to soften industrial capitalism from within rather than overthrow it.

Effects of industrialization on women and children

Wage labor outside the home for working-class women and children, and a separate-spheres ideology confining middle-class women to the household.

Framework for comparing revolutions

Who rebelled, against whom, what they demanded, and what actually changed for whom. The gap between the last two is where the analysis lives.

A revolution goes as far as its most radical necessary participants require

Elite-led revolutions stopped once elites held power; France went further because crowds and peasants entered; Haiti had to be total because anything less left people enslaved.

Toussaint Louverture

Led the Haitian revolutionaries, invoking French revolutionary principle against French slaveholders and turning the Republic's own claims into a weapon.

Haitian indemnity

France demanded an enormous payment in exchange for recognition, which Haiti paid over generations — retaliation that explains its later poverty better than anything internal.

Haiti and the Louisiana Purchase

Losing Saint-Domingue removed the point of a French North American empire, so Napoleon sold the territory. A slave revolt redrew the map of the United States.

Olympe de Gouges

Answered the Declaration of the Rights of Man with a Declaration of the Rights of Woman in 1791, showing the logic admitted no sexual exception. Guillotined during the Terror.

Mary Wollstonecraft

Argued in A Vindication of the Rights of Woman that women appeared irrational only because they were denied education — reasoning from the Enlightenment's own premises.

Limits their authors accepted

Locke invested in the Royal African Company, Jefferson enslaved people, Rousseau confined women to domestic virtue. The claims were released with limits that could not be defended in their own terms.

Nationalism as double-edged

Liberating where it mobilized resistance to empire, exclusionary where a state defined the nation narrowly. The Ottoman Empire shows both effects at once.

Why abolition succeeded

Ideas plus economics plus resistance: religious and natural-rights argument, industrial capitalism favoring wage labor, and revolt that made slavery expensive and frightening to maintain.

Compensation to owners

Britain paid former enslavers rather than the formerly enslaved when it abolished slavery in 1833 — a detail that tells you whose property the law recognized.

Enclosure

Consolidation of common land into private holdings, which raised agricultural productivity and displaced rural labor into the wage workforce industry needed.

Bottleneck sequence in textiles

Flying shuttle sped weaving and starved spinning; the jenny, water frame and mule broke that; the power loom then mechanized weaving. Each innovation created the next one's market.

Watt's separate condenser

The improvement that made the steam engine efficient enough for general use, freeing factories from riversides and driving railways and steamships.

Bessemer process

Cheap mass steel, which made railways, ships, machinery and structural building possible at a scale iron could not support.

Zollverein

German customs union removing internal tariffs, creating a single large market years before political unification and letting firms reach industrial scale.

Zaibatsu

Japanese conglomerates that bought the state's model factories, the mechanism by which Meiji state-led industrialization transferred into private hands.

Witte and Russian industrialization

State-directed railway building and foreign capital produced rapid industrial growth on a base of recently emancipated peasants and without political reform — a combination that produced 1905 and 1917.

Chartists

British working-class movement demanding suffrage and parliamentary reform, showing that industrial workers pursued political rights as well as wages.

Bismarck's social insurance

State pensions and sickness insurance adopted explicitly to weaken socialist appeal — reform as a defensive concession rather than a moral awakening.

Factory acts

Legislation limiting hours and child labor, the standard evidence that industrial societies regulated the conditions they had created once workers organized.

Meiji versus Qing reform

Both faced Western pressure; Meiji reformers held central power and used it, while the Qing court faced rebellion, foreign extraction, and blocked coordinated reform. Politics, not culture, explains the divergence.

What examiners penalize here

• For revolution comparisons, analyze **who led** and **who benefited**. Elite-led revolutions (American, much of Latin America) often preserved social hierarchies; the **Haitian** revolution, led by the enslaved, uniquely dismantled slavery. That distinction earns comparative-thinking points.
• If a prompt asks which revolution was "most radical," **name your criterion first**. By political transformation, France abolished a monarchy and a nobility. By social transformation, Haiti destroyed slavery and a planter class. By durability of institutions, the United States. Declaring the standard is what makes the answer arguable rather than assertive.

Practice World History

Our practice bank is drawn from across the whole course rather than filtered to one unit, which is closer to how the exam asks anyway — it will not tell you which unit a question is testing.
