Philippe II, Duke of Orléans

Philippe d'Orléans, Duke of Orléans, Grandson of France (2 August 1674 – 2 December 1723) was a member of the royal family of France and served as Regent of the Kingdom from 1715 to 1723. Born at his father's palace at Saint-Cloud, he was known from birth under the title of Duke of Chartres. His father was Louis XIV's younger brother Philippe I, Duke of Orléans, known as "Monsieur"; his mother was Elizabeth Charlotte of the Palatinate. 
In 1692, Philippe married his first cousin, Françoise Marie de Bourbon - the youngest legitimised daughter ("légitimée de France") of Philippe's uncle Louis XIV and Madame de Montespan. Named regent of France for Louis XV until Louis attained his majority in February 1723, the era of his "de facto" rule was known as the Regency (1715–1723). He died at Versailles in 1723. He is referred to historically as "le Régent".
