"The lecherous Fulk then fell passionately in love with the sister of Amaury of Montfort, whom no good man ever praised save for her beauty. For her sake, he divorced the mother of Geoffrey II Martel..."

Bertrade and Fulk were married, and they became the parents of a son, Fulk, but in 1092 Bertrade left her husband and took up with King Philippe. Philippe married her on May 15, 1092, despite the fact that they both had spouses living. He was so enamoured of Bertrade that he refused to leave her even when threatened with excommunication. Pope Urban II did excommunicate him in 1095, and Philippe was prevented from taking part in the First Crusade. Astonishingly, Bertrade persuaded Philippe and Fulk to be friends. Fulk of Anjou (1092 РNovember 10, 1143), king of Jerusalem from 1131, was the son of Fulk IV, count of Anjou, and his wife Bertrada (who ultimately deserted her husband and became the mistress of Philip I of France). ...

According to Orderic Vitalis, Bertrade was anxious that one of her sons succeed Philippe, and sent a letter to King Henry I of England asking him to arrest her stepson Louis. Orderic also claims she sought to kill Louis first through the arts of sorcery, and then through poison. Whatever the truth of these allegations, Louis succeeded Philippe in 1108. Bertrade lived on until 1117; William of Malmesbury says: "Bertrade, still young and beautiful, took the veil at Fontevraud Abbey, always charming to men, pleasing to God, and like an angel."
