Philip Hurepel
Philip Hurepel (1200–1234) was a son of King Philip II Augustus of France and Agnes of Merania. In 1216 he married Matilda II, Countess of Boulogne, and ruled Boulogne and Aumale in her right; in 1218 he received Clermont-en-Beauvaisis.
He joined Louis VIII on the Albigensian Crusade in 1226 and carried the sword at Louis IX's coronation. In 1229 he joined the barons' revolt against the regent Blanche of Castile, later winning pardon. He died at Corbie in 1234, supposedly killed after slaying Count Floris IV of Holland in a tournament.
