  William administered his Aquitaine duchy as both a lover of the arts an d a w a r r i or. He became involved in conflicts with Normandy, which he ra ided i n 1 1 3 6 i n alliance with Geoffrey V, Count of Anjou, who claimed i t in h i s w i f e's name and for France. Even inside his borders, William faced an alliance of the Lusignans and t h e P a r t henays against him, an issue resolved with total destruction of t h e e n e m ies. In international politics, William X initially supported an t i p o p e Anacletus II in the papal schism of 1130, opposite to Pope Innoc e n t I I , a gainst the will of his own bishops. In 1134, Saint Bernard of C l a i r v aux convinced William to drop his support for Anacletus and join I n n o c e nt.
