Definitions:

(1) (Napoleon Bonaparte)
French general and emperor who ruled (through conquest) most of continental Europe for a brief time (1769-1821)

Napoleon rose during the French Revolution, seized power in 1799, and crowned himself emperor in 1804. He expanded French influence through wars across Europe and also passed lasting reforms, especially the Napoleonic Code, which shaped modern civil law in many countries. His failed invasion of Russia (1812) began his decline; he was forced to abdicate, briefly returned to power, and was finally defeated at Waterloo (1815). He died in exile on St. Helena.
(2) (meaning too rare to warrant focus)
Less commonly, napoleon can refer to a pastry, a card game, or to anyone with that name.
