Philippe Hurepel

Philippe I Hurepel (1201 – 1235) was count of Clermont-en-Beauvais, Boulogne, Mortain, Aumale, and Dammartin. He was the son of Philip II of France and his controversial third wife Agnes of Merania. Illegitimacy shadowed his birth and career.

He was married in c. 1223 to Matilda II, countess of Boulogne (d. c. 1260), the daughter of Ida, Countess of Boulogne and her husband Renaud de Dammartin, count of Boulogne.

Young Philip became in his wife's right became count of Boulogne, Mortain, Aumale, and Dammartin. Count Philip Hurepel revolted against his sister-in-law Blanche of Castile when his elder brother Louis VIII died in 1226. When count Philip died in 1235, Matilda continued to reign and was married to Alphonse, second son of King Alfonso II of Portugal, younger brother of King Sancho II of Portugal.

Matilda and Philip had a son and a daughter who both survived Philip.

The son reportedly renounced his rights and went to England, for unknown reasons. Apparently he survived his mother the countess, but presumably did not leave issue.

The daughter, having married a lord de Chatillon-Montjay, predeceased her mother, and presumably left no surviving issue.

Thus, after Matilda, her county of Boulogne went to Matilda's relatives.
