Alberic I of Spoleto
Lombard duke of Spoleto from between 896 and 900 until 920/922
Alberic I (died c. 925) was the Lombard Duke of Spoleto from between 896 and 900 until 920, 922, or thereabouts. He was also Margrave of Camerino, and the son-in-law of Theophylact I, Count of Tusculum, the most powerful man in Rome.
Life
Early career
He first appears as a page to Guy III of Spoleto at the Battle on the Trebbia in 889. He may have later been the count of Fermo, but whatever the case, he succeeded to Spoleto after murdering Duke Guy IV.
He was recognised soon by King Berengar I, with whom he fought the Magyars in 899 or 900.
Roman alliances
Theophylact, Count of Tusculum, in the Alban Hills southeast of Rome served as palatine iudex (or leader of the militia) for Emperor Louis III. He remained in Rome, commanding a group of soldiers after the emperor's return to Provence in 902, and was prominent in the overthrow of Antipope Christopher in January 904. Together with Alberic, they secured the succession of Pope Sergius III. Under Sergius, Theophylact became both sacri palatii vestararius and magister militum. As the first oversaw appointments, and the second supervised the soldiers, Theophylact had effective control of the city. Theophylact was married to Theodora. They had two daughters: Marozia and Theodora.
This brief starts where responsible research should: with the source description of “Alberic I of Spoleto” as lombard duke of Spoleto from between 896 and 900 until 920/922. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as lombard duke of Spoleto from between 896 and 900 until 920/922. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 4, 2026. The linked authority identifier is Q433400. VIAF identifies the subject as 213159474304227662184. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
