The state originated in the 10th century as property of the Lords of Bouillon, owners of Bouillon Castle. Crusader Godfrey of Bouillon, later the first King of Jerusalem, sold Bouillon to the Prince-Bishopric of Liège, in 1095. The Prince-Bishops of Liège consequently became lords of Bouillon and eventually adopted the title of duke. The duchy was later claimed by members of the Houses of La Marck and La Tour d'Auvergne. From 1678, it was a sovereign duchy under French protection and ruled by La Tour. It was annexed by France in 1795.
