Monsieur Philippe I, Duke of Orléans (21 September 1640 – 9 June 1701), was the younger son of King Louis XIII of France and his wife, Anne of Austria. His elder brother was the "Sun King", Louis XIV. Styled Duke of Anjou from birth, Philippe became Duke of Orléans upon the death of his uncle Gaston in 1660. In 1661, he also received the dukedoms of Valois and Chartres. Following Philippe's victory in battle in 1671, Louis XIV granted his brother the dukedom of Nemours, the marquisates of Coucy and Folembray, and the countships of Dourdan and Romorantin.
