Philip II, byname Philip Augustus, was King of France from 1180 to 1223. His predecessors had been known as kings of the Franks, but from 1190 onward, Philip became the first French monarch to style himself "King of France". The son of King Louis VII and his third wife, Adela of Champagne, he was originally nicknamed Dieudonné (God-given) because he was a first son and born late in his father's life. Philip was given the epithet "Augustus" by the chronicler Rigord for having extended the crown lands of France so remarkably.
