Philip II Augustus (French: Philippe Auguste) (21 August 1165 – 14 July 1223) was the King of France from 1180 until his death.
A member of the House of Capet, Philip Augustus was born at Gonesse in the Val-d’Oise, the son of Louis VII and his third wife, Adela of Champagne. He was originally nicknamed *Dieudonné*—the God-given—as he was the first son of Louis VII late in his father’s life.
Philip was one of the most successful medieval French monarchs in expanding the royal demesne and the influence of the monarchy. He broke up the great Angevin Empire and defeated a coalition of his rivals (German, Flemish and English) at the Battle of Bouvines in 1214. He reorganized the government, bringing financial stability to the country and thus making possible a sharp increase in prosperity. His reign was popular with ordinary people because he checked the power of the nobles and passed some of it on to the growing middle class.
Philip went on the Third Crusade (1189–1192) with Richard I. of England (1189–99), his very close friend.
