 Originally it was a suffragan (under the supervision) of the diocese of Milan, but at the end of the 5th century became a suffragan of Ravenna.Because of the schism of the Antipope Clement III, Pope Paschal II, at the Council of Guastalla in October 1106, released Bologna from obedience to the church of Ravenna, and made it directly dependent on the papal See; but on 7 August 1118 Pope Gelasius II restored the previous status.Bishop Victor, therefore, enjoyed the privilege of being consecrated a bishop by Pope Paschal II in 1108.
