Geoffrey II, called Martel ("the Hammer"), was Count of Anjou from 1040 to 1060. He was the son of Fulk the Black. He was bellicose and fought against William VII, Duke of Aquitaine, Theobald I, Count of Blois, and William, Duke of Normandy. During his twenty-year reign he especially had to face the ambitions of the Bishop of Le Mans, Gervais de Château-du-Loir, but he was able to maintain his authority over the County of Maine.
