Philip I, Count of Boulogne

Philip I of Boulogne (Philip Hurepel) (1201–1235) was Count of Clermont-en-Beauvaisis, 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 associated with founding the Tour du Guet in Calais, France.

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, in right of his wife, 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, Alberic and a daughter, Joan who both survived Philip.

Alberic reportedly renounced his rights and went to England, for unknown reasons. Apparently he survived his mother the countess and died in 1284, but presumably did not leave issue.

Joan, married in 1236 to Gaucher de Châtillon, comte de Mortain (d. 1251), predeceased her mother in 1252, and presumably left no surviving issue.

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