Charles Honoré d'Albert, duc de Luynes

Charles Honoré d'Albert de Luynes (; 7 October 1646 – 5 November 1712) was a French nobleman and Duke of Luynes. He is best known as the Duke of Chevreuse, his family's subsidiary title which he used until his father's death in 1690. He was a high-ranking French official under King Louis XIV.

Early life He was the eldest son of Louis Charles d'Albert de Luynes (1620–1699), 2nd Duke of Luynes and Louise Marie Séguier, Marquise d'O (1629–1651). After his mother's death, his father remarried to Princess Anne de Rohan-Montbazon (1640–1684), with whom he had five more children, including his half-sister Jeanne Baptiste d'Albert de Luynes, the mistress of Victor Amadeus II of Sardinia. After her death in 1684, his father married, thirdly, to Marguerite d'Aligre in 1685.

The Duke of Chevreuse was the grandson of the French courtier and favourite of Louis XIII, Charles d'Albert, duc de Luynes, and the former Marie de Rohan, the infamous duchesse de Chevreuse and one of the leading members of the Fronde.

Career The duc de Chevreuse was a private advisor of Louis XIV, and a sort of unofficial minister without portfolio. From 1698 until 1712 he was the non-residing governor of the province of Guienne (from the time of Louis XIV onwards the governorship of French provinces was essentially an honorific title and governors were not allowed to reside or even visit their provinces).

Friend of the Duke of Beauvilliers and of the famous archbishop François Fénelon, he maintained a steady exchange of correspondence with the latter. It is at the Duke of Chevreuse's estate in Chaulnes (Somme department) that Fénelon wrote his Tables de Chaulnes (1711).
