The French Revolution occurred from 1789-1815 and went through several stages: the National Assembly, Constitutional Monarchy, Reign of Terror under Robespierre, and the Directory. It was sparked by Enlightenment ideas, economic crisis, and influence of the American Revolution. Key events included the storming of the Bastille and execution of Louis XVI. Napoleon later rose to power as leader of the Consulate and First French Empire, though he was finally defeated at Waterloo in 1815. The Congress of Vienna following Napoleon sought to restore the monarchies and balance of power in Europe to prevent further revolution.
