アンジュー帝国
During the earlier medieval period, Auvergne was a county within the duchy of Aquitaine and as such part of the "Angevin Empire" until the 13th century. In 1225, Louis VIII of France granted Poitou and Auvergne to his third son Alfonso. On Alfonso's death in 1271, Auvergne, along with the County of Toulouse, Poitou and the Comtat Venaissin, reverted to the royal domain.
