Alberic II of Spoleto
He was of the house of the Counts of Tusculum, the son of the notorious Marozia by her first husband, Alberic I, Duke of Spoleto. His half-brother was Pope John XI. At the wedding of his mother to King Hugh of Italy, Alberic and his new stepfather quarreled violently after Hugh slapped Alberic for clumsiness. Infuriated by this and perhaps motivated by rumors that Hugh intended to have him blinded, Alberic left the festivities and incited a Roman mob to revolt against Hugh. In December 932 Hugh fled the city, Marozia was cast into prison, and Alberic took control of Rome. In 936 Alberic married his stepsister Alda, the daughter of King Hugh, and had a son with her, Octavian. On his deathbed he nominated his son as Pope John XII.
