Alberik II is a historical name borne by at least two notable figures from the early and high Middle Ages.
1. Alberik II of Utrecht (also Albricus or Alfrik)
Alberik II was Bishop of Utrecht from approximately 835 to 844. He was the brother of his predecessor, Frederick of Utrecht. Little is known about his administration. He is recorded as having accepted a significant donation of land for his church from a Count Rodgar before 23 March 838, and he likely attended a bishops' council in Aachen on 30 April 838. During his episcopate, the Netherlands were raided by Norse Vikings, and Alberik was sometimes forced to flee. According to the necrologium of Oudmunster, he died on 28 August, likely in 844, as his successor Eginhard appears in records by 21 March 845. He was buried in the Saint Salvator Church in Utrecht, and his epitaph has been preserved.
2. Alberic II of Spoleto (c. 912–954)
Alberic II (also known as Alberico di Roma) was the princeps (prince) and effective ruler of Rome from 932 until his death in 954. He was a member of the powerful Roman House of Theophylact, the son of Marozia and Alberic I of Spoleto, and the half-brother of Pope John XI.
After his mother Marozia married Hugh of Italy in 932, Alberic (then a teenager) led a popular revolt, driving Hugh out of Rome and imprisoning Marozia. He subsequently ruled Rome for 22 years under the titles princeps and senator omnium Romanorum (senator of all the Romans), a title recognized by Byzantine Emperor Constantine VII.
Alberic II exercised total control over the papacy, personally appointing the five popes who succeeded John XI: Leo VII, Stephen VIII, Marinus II, Agapetus II, and ultimately his own son Octavian, who became Pope John XII in 955. His reign was a period of relative peace for Rome, and he was noted for restoring monasteries that had been abandoned due to Muslim raids, earning the epithet cultor monasteriorum (cultivator of monasteries) from the chronicler Benedict of Soracte. He denied Otto the Great a coronation as Holy Roman Emperor in 951. Alberic died in Rome on 31 August 954.
