Count of Ponthieu

The County of Ponthieu (French: Comté de Ponthieu, Latin: Comitatus Pontivi), centered on the mouth of the Somme, became a member of the Norman group of vassal states when Count Guy submitted to William the Conqueror, Duke of Normandy after the battle of Mortemer. It eventually formed part of the dowry of Eleanor of Castile and passed to the English crown. Much fought-over in the Hundred Years' War, it eventually passed to the French royal domain, and the title Count of Ponthieu (comte de Ponthieu) became a courtesy title for the royal family.
