Duke Of Longueville

The title was created in 1505 by King Louis XII of France for his first cousin once removed, François d'Orléans, Count of Dunois, son of François d'Orléans, Count of Dunois, son of Jean d'Orléans, himself an illegitimate son of the Duke of Orléans. The title became extinct in 1694, following the death of Jean Louis Charles d'Orléans, who was the brother of Marie de Nemours.

From 1648, the Duke of Longueville was also Sovereign Prince of Neuchâtel, a Swiss territory. In 1654, the eighth duke was created a peer as Duke of Coulommiers, but the peerage was never registered and so became extinct at his death.
