Boniface of Savoy was a medieval Bishop of Belley in Savoy and Archbishop of Canterbury in England. He owed his initial ecclesiastical posts to his father and held various positions within the church. Boniface clashed with his bishops, his nephew-by-marriage, and the papacy during his tenure as Archbishop, but he successfully managed to eliminate the archiepiscopal debt. Initially supporting Simon de Montfort, Boniface later switched allegiance to King Henry III. He was eventually beatified in 1839.

Antipope Gregory VIII, also known as Mauritius Burdinus, held the position of antipope from March 10, 1118, to April 22, 1121. During his time in this role, he engaged in various political and religious activities, challenging the legitimacy of the pope and attempting to assert his own authority within the Catholic Church. Despite his brief tenure, Gregory VIII played a significant role in the ecclesiastical politics of his era, leaving a mark on the history of papal succession and the power struggles within the Church.
