Philip-Augustus, king of France, shared the throne with his father, Louis VII., from 1179, and succeeded him as sole ruler in 1180; marrying Isabella of Hainault, he united the Capet and Carlovingian houses; his grand aim was to secure to himself some of the English possessions in France; his alliance with Richard of England in the third crusade ended in a quarrel; returning to France he broke his oath to Richard by bargaining with John for portions of the coveted territory; an exhausting war lasted till 1119; on Richard's death Philip supported Arthur against John in his claim to Anjou, Maine, and Touraine; after Arthur's murder, the capture of Chateau Gaillard in 1204 gave him possession of these three provinces with Normandy and part of Poitou; the victory of Bouvines 1214 secured his throne, and the rest of his reign was spent in internal reforms and the beautifying of Paris (1165-1223).
