What this topic is asking
Topic 5.4 asks you to explain the French Revolution: its causes, its liberal opening phase in 1789, and its descent into the radical phase and the Terror. The College Board wants you to understand why the old regime collapsed in France and how the Revolution moved from reform to radicalism.
The causes
The liberal phase, 1789
When the fiscal crisis forced Louis XVI to summon the Estates-General, the Third Estate, frustrated by the voting system, broke away to form a National Assembly claiming to represent the nation. Popular uprisings (symbolised by the storming of the Bastille) gave the Revolution force.
The radical phase and the Terror
Why it mattered
The French Revolution is the central event of Unit 5 and one of the most consequential in European history. It destroyed the old regime in France, proclaimed principles, liberty, equality, popular sovereignty, that would reshape European politics, and unleashed forces (nationalism, mass mobilization, ideological warfare) that defined the 19th century. Its effects spread across Europe (Topic 5.5), its instability opened the way for Napoleon (Topic 5.6), and the reaction against it shaped the Congress of Vienna (Topic 5.7).
