From her French mother, whose parents had fled Haiti in the Revolution of 1791, had come her slanting dark eyes, shadowed by inky lashes, and her black hair; and from her father, a soldier of Napoleon, she had her long straight nose and her square-cut jaw that was softened by the gentle curving of her cheeks.

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.
