Antoine Philippe, Duke of Montpensier

Louis Antoine Philippe d'Orléans, Duke of Montpensier (French pronunciation: [lwi ɑ̃twan filip dɔʁleɑ̃]; 3 July 1775, in Palais-Royal, Paris – 18 May 1807, in Salthill, England) was a son of Louis Philippe, Duke of Orléans (nom de rėvolution: "Philippe Égalité") (1747–1793), and his duchess Louise Marie Adélaïde de Bourbon, Duchess of Orléans. He was the younger brother of Louis Philippe, later King of the French. Antoine had a deep affection for him, and they were only ever separated during the Reign of Terror and the events that followed between 1793 and 1797.
