Eugène Rose de Beauharnais (3 September 1781 – 21 February 1824), was the first child and only son of Alexandre de Beauharnais and Joséphine Tascher de la Pagerie, future wife of Napoleon I. He was born in Paris, France and became the stepson and adopted child (but not the heir to the imperial throne) of Napoleon I. His biological father was executed during the revolutionary Reign of Terror. He commanded the Army of Italy and was Viceroy of Italy under his stepfather. Historians have looked upon him as one of the ablest of Napoleon's relatives.
