Alberic II, Prince and Senator of all Romans, was the son of Alberic I, Duke of Spoleto and Marozia.[1][2] He was born about 914, probably in the family palace on the Aventine (Aventine Hill).[3]

Alberic II's mother, Marozia, was married three times, her third husband being King Hugh of Italy. At the 932 wedding of Hugh and Marozia, it is said that Hugh slapped Alberic for being clumsy and an infuriated Alberic left the festivities and launched a Roman revolt against Hugh. By Dec 932 Alberic had successfully overthrown Hugh's reign. Hugh had fled the city and Marozia was imprisoned (where she remained for five years, until her death), leaving Alberic free to take control of Rome.[1]

Alberic II married about 936 to Alda, daughter of Hugh, King of Italy,[2] his step-sister.[4] They had children:

  • Octavianus, c.936 - 14 May 964 (disputed mother), who would become (Pope John XII);[2]
  • Theophylact (possibly).

Alberic II became the absolute ruler at Rome after the downfall of his mother and stepfather in 932,[2][5] being elected by the Romans as their prince.[3] Alberic II remained "Prince and Senator of all the Romans" for over 20 years.[1] From the time he gained power, Alberic prohibited the papacy from exerting any secular or political influence, limiting its authority to spiritual matters.[1][3] Alberic had total control over the reign of five Popes: Alberico's brother[6] (or half-brother), John XI (931-935); Leo VII (936-939); Stephen VIII (939-942); Marinus II (942-946); and Agapietus II (946-955). His reign was responsible for the following:[3]

  • Strengthening of the Roman militia;
  • Removal of courts of justice from the Vatican, in the presence of the pope, to the Princeps of Rome at various places, including his own palace in the Via Lata;
  • Defending Rome against two attacks by Hugo, in 933 and 936;
  • Monastic reform, employing the system of Odo of Cluny to restore discipline;
  • Refusal to admit Otto, the German King, to Rome in 952.

Before Alberic II died, he realized that "the separation of the temporal power from the Papacy in Rome was impossible" and he took steps toward their reunification.[1] On 31 Aug 954, Alberic assured his son's papacy by gathering the Roman nobility and clergy in St. Peters and having them swear an oath that his son (Octavianus) would be the next in line for the papal chair.[1][3] When Pope Agapetus II died in 955, Octavianus was elected to head the Catholic Church on 16 Dec 955, as expected.[5]

Alberic II died in 954,[1][5] perhaps on 31 Aug,[6] and was succeeded by his son, Octavianus as Prince of Rome.[1][3]
