According to his biographer in the Liber Pontificalis, Innocent was a native of Albano Laziale and the son of a man called Innocentius, but his contemporary Jerome referred to him as the son of the previous pope, Anastasius I, probably a unique case of a son succeeding his father in the papacy. According to Urbano Cerri, Pope Innocent was a native of Albania. He was the bishop of Rome from 401 to his death on 12 March 417. From the beginning of his papacy, he was seen as the general arbitrator of ecclesiastical disputes in both the East and the West. Accordingly, his feast day is celebrated on 12 March, though from the thirteenth to the twentieth century he was commemorated on 28 July.
