Hortense (born April 10, 1783, Paris, France—died October 5, 1837, Arenenberg, Switzerland) was the queen of Holland, stepdaughter of Napoleon I, and mother of Napoleon III.
The daughter of the future empress Joséphine and of her first husband, Alexandre de Beauharnais, Hortense became one of the attractions of the court after Napoleon became first consul of the French in 1799. To strengthen her position, Joséphine encouraged a marriage between Hortense and Louis Bonaparte, Napoleon’s brother (1802). The marriage, although an unhappy one, produced three children, the third of whom, Charles-Louis-Napoléon Bonaparte, survived to become Napoleon III. In 1806, when Louis became king of Holland, Hortense accompanied him to The Hague. Although Napoleon divorced Joséphine in 1809, he refused to allow Hortense and Louis a divorce but countenanced their separation in 1810, when Holland was annexed to France. Returning to Paris, Hortense in 1811 gave birth to a son by her lover, the comte de Flahaut; this son, who was adopted by a relative, was the future duc de Mornay.
When Napoleon was exiled in 1814, Hortense, although under the protection of the allies and created duchesse de Saint-Leu, became the centre of Bonapartist intrigue; and her support of Napoleon during his return (the Hundred Days) led to her banishment from France in 1815. She finally settled in Arenenberg, Switzerland, where she lived until her death, devoting herself to her writing and to the protection of her sons. Her memoirs were published between 1831 and 1835 (Eng. trans., Memoirs of Queen Hortense, 2 vol., 1862).
