Matilda II, Countess of Boulogne

Matilda II of Dammartin (1202–1259) inherited Boulogne from her mother Ida in 1216. In 1223 she married Philip Hurepel, son of Philip II of France, and reigned with him as co-ruler until he died in 1234. In 1238 she married the Portuguese infante Afonso, who became Afonso III in 1248, renounced Boulogne and made her queen of Portugal.

They had no surviving children, and she reportedly was not allowed to follow him to Portugal. They divorced in 1253. In 1258 she charged Afonso with bigamy before Pope Alexander IV over his marriage to Beatrice of Castile. She died in January 1259.
