The French Revolution began in 1789 and overthrew the French monarchy and feudal system. It established a constitutional monarchy that gradually gave way to a republic as King Louis XVI was executed in 1793. The Revolution was influenced by Enlightenment ideas on equality, representation and inalienable rights and led to the Declaration of the Rights of Man and of the Citizen. However, the Revolution also saw the rise of Robespierre and the Reign of Terror as he established a dictatorship before being overthrown. Napoleon later crowned himself Emperor in 1804 but was eventually defeated at the Battle of Waterloo in 1815.
