The document summarizes the key periods and causes of the French Revolution. It describes the unequal system of estates that existed under the Old Regime, with the Third Estate bearing the heaviest tax burden despite comprising the majority of the population. Dissatisfaction grew until the Third Estate formed the National Assembly and took the Tennis Court Oath to draft a constitution, limiting the monarch's power. After the storming of the Bastille, Louis XVI accepted demands for reform, abolishing privileges of the clergy and nobility and confiscating church lands. The monarchy was later abolished and France became a republic.
