> William Isarn was the Count of Ribagorza from 1010 until his death in 1017 or 1018. He was a young man when he became party to a power-sharing agreement between his cousin and her husband, sponsored by the Count of Castile. He used a Castilian army to remove the Muslim garrisons from the valley of the Isábena, but before his work of Reconquista could be completed, he was assassinated while trying to reestablish his family's rights in the Val d'Aran. His death provoked a succession crisis that ended in the absorption of Ribagorza into the domains of the King of Navarre.
