AP World History Unit 5 Essentials

The political revolutions of 1750–1900 didn't emerge from nowhere — they were powered by new ideas about human nature, rights, and government. Enlightenment thinkers argued that government must serve the people, not the other way around. These ideas spread through print culture, coffeehouses, and salons, creating a new political vocabulary that revolutionaries across the Atlantic world used to justify their actions.

The Atlantic revolutions did not happen in isolation. The American Revolution inspired the French; the French Revolution inspired the Haitian; the Haitian Revolution terrified slaveholders across the Americas. Latin American independence leaders read Locke and Rousseau. Ideas, people, and pamphlets crossed the Atlantic, creating a revolutionary wave that reshaped the political order.

The revolutionary rhetoric of liberty and equality was selectively applied. The American Revolution preserved slavery. The French Revolution excluded women from political rights. Latin American independence replaced Spanish rule with Creole elites — Indigenous people and Africans saw little change. The Haitian Revolution is the notable exception, but it faced international isolation as punishment for its radicalism.

The concept of the nation-state — that political borders should reflect cultural or ethnic communities — reshaped the global map. In Europe, nationalist movements unified Italy and Germany and challenged the Ottoman and Austro-Hungarian empires. In the Americas, new nations forged distinct identities. Nationalism was a revolutionary force — but also a dangerous one, planting seeds for the conflicts of Unit 7.
