アンジュー帝国
During the reign of the closely related Plantagenet dynasty, which was based in its Angevin Empire, and at the height of the empires size, 1/3 of France was under Angevin control as well as all of England. However, almost all of the Angevin empire was lost to Philip II of France under Richard the Lionheart, John and Henry III of England. This finally gave the English a separate identity as an Anglo-Saxon people under a Francophone, but not French, crown.
