130th Pope of the Catholic Church. Pontificate 955 - 964. Before his death in 954, Alberic administered an oath to the Roman nobles in St. Peter's providing that the next vacancy for the papal chair would be filled by his son Octavianus. He succeeded his father as Patrician of Rome in 954 at only seventeen years of age. After the death of Agapetus II in November 955, Octavanius was actually chosen his successor on 16 December 955 at the age of eighteen. Pope John XII was depicted as a coarse, immoral man in the writings which remain about his papacy, whose life was such that the Lateran was spoken of as a brothel, and the moral corruption in Rome became the subject of general disgrace.
