The French Revolution was a period of extreme political and social change in late 18th century France led by Maximilien Robespierre, who came to power during the Reign of Terror where those who opposed him could be executed. Robespierre headed the Committee of Public Safety and established a repressive regime until he himself was executed in 1794, but the Revolution influenced modern European political thought, increased citizen participation in government, and changed the political landscape of Europe permanently.
