When her son Amalric seized power in 1306, Queen Isabella and her brother Philip unsuccessfully supported her older son King Henry.[5] Amalric was murdered on 5 June 1310, and another son, Aimery, was proclaimed governor in his stead.[6] But by 11 June, supporters of the imprisoned king contacted their mother, Queen Isabella, papal representatives, and Aimery's party. Aimery was outnumbered and agreed with his supporters to restore Henry in return for Isabella's promise to persuade Henry to pardon them and to ratify legal transactions they made.[7] Envoys reported to King James II of Aragon, husband of Isabella's daughter Maria, that Isabella and Philip dominated Henry's court in the rest of his reign.[8]
