Geoffrey IV, Count of Anjou
(重定向自Geoffrey IV)
Geoffrey IV (1070/5 – 19 May 1106), called Martel (the Hammer), was Count of Anjou from 1103 until his early death, either co-ruling with his father, Fulk IV, or in opposition to him. He was popular with the Church and grew a reputation for curbing tyranny and opposing his violent father, who, according to Orderic Vitalis, enjoyed pillaging and terrorising his subjects.
