Pope Innocent I () 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. He confirmed the prerogatives of the Archbishop of Thessalonica, and issued a decretal on disciplinary matters referred to him by the Bishop of Rouen. He defended the exiled John Chrysostom and consulted with the bishops of Africa concerning the Pelagian controversy, confirming the decisions of the African synods. The Catholic priest-scholar Johann Peter Kirsch, 1500 years later, described Innocent as a very energetic and highly gifted individual "...who fulfilled admirably the duties of his office".

He took a decided view on the Pelagian controversy, confirming the decisions of the synod of the province of proconsular Africa, held in Carthage in 416, confirming the condemnation which had been pronounced in 411 against Cælestius, who shared the views of Pelagius. He also wrote in the same year in a similar sense to the fathers of the Numidian synod of Mileve who had addressed him. Soon after this, five African bishops, among them St. Augustine, wrote a personal letter to Innocent regarding their own position in the matter of Pelagianism. In addition he acted as metropolitan over the bishops of Italia Suburbicaria. The historian Zosimus in his Historia Nova suggests that during the sack of Rome in 410 by Alaric I, Innocent I was willing to permit private pagan practices as a temporary measure. However,
