2.3 Atlantic Revolutions & Nationalism

Key Takeaways

  • Enlightenment ideas of natural rights and popular sovereignty triggered a wave of Atlantic Revolutions: American (1776), French (1789), Haitian (1791), and Latin American (1810s-1820s).
  • The French Revolution moved through phases - moderate (1789), radical Reign of Terror (1793-94), and Napoleon's rise (1799) - then spread revolutionary and nationalist ideas across Europe.
  • The Haitian Revolution, led by Toussaint L'Ouverture, produced the first successful large-scale slave revolt and the first Black republic (1804).
  • Simon Bolivar and Jose de San Martin led Latin American independence movements that freed most of Spanish South America by the 1820s.
  • Nationalism - loyalty to a shared nation - both unified peoples (Italy under Cavour/Garibaldi, Germany under Bismarck by 1871) and fragmented multiethnic empires.

A Connected Age of Revolution

The second half of unit 10.2 is the Atlantic Revolutions, one of the most tested clusters on Global II. The key idea is that these were connected: Enlightenment principles — natural rights, the social contract, and popular sovereignty — crossed the Atlantic and produced a chain reaction. The exam loves cause-and-effect and comparison questions across these revolutions, so study their shared causes and distinct outcomes side by side.

The shared causes are easy to memorize as a set: Enlightenment ideas (natural rights, popular sovereignty), economic grievances (taxes, debt, inequality), and a weakened or distant central authority that could no longer control its colonies or subjects. What changes from one revolution to the next is who leads it and what kind of society results.

The French Revolution: Causes, Phases, Napoleon

The French Revolution gets the most detail. Causes: France was divided into Three Estates — the First (clergy) and Second (nobility) paid little tax, while the Third Estate (commoners, ~97% of people) bore the burden. Combine that inequality with state bankruptcy (worsened by France's costly support of the American Revolution), bread shortages, and Enlightenment ideas, and the system collapsed. Notice the cause-and-effect link the exam often tests: France helped the American colonists win, then went broke doing so, which helped trigger its own revolution.

Phases (know the sequence):

  1. Moderate phase (1789): The Third Estate formed the National Assembly and swore the Tennis Court Oath; the Bastille fell on July 14, 1789; the Declaration of the Rights of Man proclaimed liberty and equality.
  2. Radical phase / Reign of Terror (1793–1794): France became a republic, executed King Louis XVI, and under Maximilien Robespierre and the Committee of Public Safety used the guillotine against "enemies of the revolution."
  3. Napoleon (1799–1815): Napoleon Bonaparte seized power in a coup (1799), crowned himself emperor (1804), and issued the Napoleonic Code (legal equality, but rolled back some rights). His conquests spread revolutionary ideas and nationalism across Europe before his defeat at Waterloo (1815); the Congress of Vienna (1814–15) then tried to restore the old order.

The Haitian Revolution

In the French sugar colony of Saint-Domingue, enslaved Africans rose in 1791. Toussaint L'Ouverture organized the revolt; after his capture, Jean-Jacques Dessalines completed independence in 1804, creating Haiti — the first Black republic and the only state born of a successful large-scale slave revolt. It is the clearest proof that revolutionary natural-rights ideas could be turned against the slaveholders who proclaimed them.

The Haitian Revolution is a favorite comparison prompt because it shows the limits and contradictions of the French Revolution: France declared the "rights of man" yet kept slavery in its colonies, and the enslaved people of Saint-Domingue took those words literally.

Latin American Independence

In Spanish America, Creoles (American-born people of Spanish descent) resented control by peninsulares (Spain-born officials). When Napoleon's invasion of Spain weakened the crown, independence movements surged. Simon Bolivar ("The Liberator") freed much of northern South America (Venezuela, Colombia, Ecuador, Bolivia); Jose de San Martin liberated Argentina, Chile, and Peru from the south. In Mexico, priests Miguel Hidalgo and Jose Morelos launched the independence struggle.

By the mid-1820s most of mainland Spanish America was independent, though Bolivar's dream of a united "Gran Colombia" fragmented into separate republics. A key contrast with the American Revolution is the outcome: the United States built a single stable republic, while Spanish America split into many nations often led by strongmen, partly because of geography, rigid colonial social hierarchies, and the absence of a long tradition of self-government.

Nationalism and Unification

The revolutions unleashed nationalism — loyalty and devotion to a shared nation defined by common language, culture, or history. Nationalism cut two ways:

  • Unification: In the later 1800s it built new nation-states. Italy was unified by 1870 through Camillo di Cavour's diplomacy and Giuseppe Garibaldi's Red Shirts. Germany was unified in 1871 by Prussia's Otto von Bismarck, who used "blood and iron" — three wars — to forge an empire.
  • Fragmentation: In multiethnic empires like Austria-Hungary and the Ottoman Empire, nationalism pulled diverse peoples apart, as Greeks, Serbs, and others sought their own states. This instability fed directly into 20th-century conflict, including the tensions in the Balkans that helped spark World War I.

The takeaway is that nationalism is double-edged: the same force that built Italy and Germany also tore apart older empires. The exam often pairs a unification example with a fragmentation example and asks you to identify the common underlying force — nationalism — behind both opposite-looking outcomes.

Expect comparison questions: every Atlantic Revolution shared Enlightenment causes, but their outcomes — a republic, a terror, a slave-led nation, a continent of new states — differed sharply.
