Philippe I, Duke of Orléans (21 September 1640 – 9 June 1701), was the younger son of Louis XIII of France and his wife, Anne of Austria. His older brother was Louis XIV, le roi soleil. Styled Duke of Anjou from birth, Philippe became Duke of Orléans upon the death of his uncle Gaston in 1660. In 1661, Philippe also received the dukedoms of Valois and Chartres. Following Philippe's victory in battle in 1671, Louis XIV added the dukedom of Nemours, the marquisates of Coucy and Folembray, and the countships of Dourdan and Romorantin. During the reign of his brother he was known simply as Monsieur, the traditional style at the court of France for the younger brother of the king.
