Duchess of Nemours

Duke of Nemours
First holder	Orson
Last holder	Charles Philippe d'Orléans

In the 12th and 13th centuries the Lordship of Nemours, in the Gatinais, France, was a possession of the house of Villebéon, a member of which, Gautier, was marshal of France in the middle of the 13th century. The lordship was sold to King Philip III of France in 1274 and 1276 by Jean and Philippe de Nemours, and was then made a county and given to Jean III de Grailly, captal de Buch in 1364.

In 1404, Charles VI of France gave it to Charles III of Navarre, and erected it into a duchy in the peerage of France, in exchange to his ancestral county of Évreux in Normandy.

After being confiscated and restored several times, the duchy reverted to the French crown in 1504, after the extinction of the house of Armagnac-Pardiac. In 1507 it was given by Louis XII of France to his nephew, Gaston de Foix, who was killed at the Battle of Ravenna in 1512. The duchy then returned to the royal domain, and was detached from it successively for Giuliano de Medici and his wife Philiberta of Savoy in 1515, for Louise of Savoy in 1524, and for Philip of Savoy, Count of Genevois, in 1528.

The descendants of Philip of Savoy held the duchy until its sale to Louis XIV of France. In 1672, Louis gave it to his brother Philippe de France, Duke of Orleans, whose descendants held it until the French Revolution. It was one of the many subsidiary titles held by the House of Orléans.
