Hortense Eugénie Cécile Bonaparte (French pronunciation: [ɔʁtɑ̃s øʒeni sesil bɔnapaʁt]; née de Beauharnais, pronounced [də boaʁnɛ]; 10 April 1783 – 5 October 1837) was Queen of Holland as the wife of King Louis Bonaparte. She was the stepdaughter of Emperor Napoléon I as the daughter of his first wife, Joséphine de Beauharnais. Hortense later married Napoléon I's brother, Louis, making her Napoleon's sister-in-law. She became queen consort of Holland when Louis was made King of Holland in 1806. She and Louis had three sons: Napoléon-Charles Bonaparte; Napoleon III, Emperor of the French; and Louis II of Holland. She also had an illegitimate son, Charles, Duke of Morny, with her lover, the Comte de Flahaut.
