Bertrade of Montfort

Bertrade of Montfort (c. 1070 – 14 February 1117), also known by other names, was a Norman noble from the House of Montfort. She was countess of Anjou (1089–1092) through her first marriage to Fulk the Rude and then queen consort of France (1092–1108) through her initially bigamous marriage to Philip I. Condemned in her era's ecclesiastical histories, she played a role in the popularization of pigache footwear and founded a daughter house of Fontevraud Abbey at Hautes-Bruyeres.
