French county From Wikipedia, the free encyclopedia
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.[1][2]
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.
