The French Revolution began in 1789 and overthrew the French absolute monarchy and feudal system of government. Financial troubles and new Enlightenment ideas led the Third Estate to revolt and form the National Assembly. This sparked the storming of the Bastille and spread of rebellion across France. The Revolution established a constitutional monarchy at first, then a republic after deposing and executing King Louis XVI. The Reign of Terror followed under Robespierre and the Committee of Public Safety, until his overthrow in the Thermidorian Reaction. Napoleon later rose to power as First Consul and crowned himself Emperor in 1804.
