William the Conqueror
While William was building his power in Normandy things were changing around him. King Henry had supported him and William had helped the king against the count of Anjou. About 1052 Count Geoffrey of Anjou and the king suddenly made peace. Just as suddenly the king turned on William. At the same time two of William's uncles, Archbishop Mauger and Count William of Arques rebelled against their nephew. William fought his uncle at the castle at Arques. King Henry now led a large force (army) into Normandy to help Count William of Arques. But Duke William met him in battle and won. Without the king's army to help, the castle had to give up. Duke William sent his two uncles away from Normandy.
