Napoleon I (born August 15, 1769, Ajaccio, Corsica—died May 5, 1821, St. Helena Island) French general, first consul (1799–1804), and emperor of the French (1804–1814/15), one of the most celebrated personages in the history of the West. He revolutionized military organization and training; sponsored the Napoleonic Code, the prototype of later civil-law codes; reorganized education; and established the long-lived Concordat with the papacy.

Napoleon’s many reforms left a lasting mark on the institutions of France and of much of western Europe. But his driving passion was the military expansion of French dominion, and, though at his fall he left France little larger than it had been at the outbreak of the Revolution in 1789, he was almost unanimously revered during his lifetime and until the end of the Second Empire under his nephew Napoleon III as one of history’s great heroes.
