Geoffrey III, Count of Anjou
As the situation in Anjou became worse Fulk argued with his brother Geoffrey. Finally, in 1067, Fulk rebelled and took the county away from Geoffrey, briefly imprisoning him. In 1068 Geoffrey attacked Fulk, and once again he was defeated. This time Geoffrey was imprisoned where he remained for 28 years. Geoffrey was finally freed by the intervention of Pope Urban II in 1096. But Geoffrey died soon after his release.
