He was the nephew of his immediate predecessor, John XIX. In October 1032, Benedict's father obtained his election through bribery. However, his reputed dissolute activities provoked a revolt on the part of the Romans. Benedict was driven out of Rome and Sylvester III elected to succeed him. Some months later, Benedict and his supporters managed to expel Sylvester. Benedict then decided to abdicate in favor of his godfather, Gregory VI, provided he was reimbursed for his expenses. Benedict subsequently had second thoughts and returned, and attempted to depose Gregory. A number of prominent clergymen appealed to King Henry III of Germany to restore order. Henry and his forces crossed the Brenner Pass into Italy, where he summoned the Council of Sutri to decide the matter. Benedict, Sylvester, and Gregory were all deposed. Henry then had Clement II elected in December 1046.
