Альфонсо III
Pope Nicholas IV crowned Charles king in Rieti on Whit Sunday 1289. To persuade Charles to continue the war for Sicily, the pope granted the tenth of Church revenues from Southern Italy to him. The pope also absolved Charles from the promises that he had made to secure his release. Edward I of England protested against the pope's decision and continued to mediate between Charles and Alfonso III of Aragon. At Edward's request, Alfonso III released Charles Martel in exchange for Charles' fifth son, Raymond Berengar.
