ALBERIC I, aka Alberico, Marchese di Spoleto[1]/Duke of Spoleto, (d. 924/26).[2] His origins are unknown, but he may have had Lombardian ancestors who lived in Spoleto or Tuscany, maybe in Horta.[3]


Alberic I married Marozia (c.890 - 937), daughter of Theophylact I (aka Teofilatto), Count of Tusculum and Theodora.[1][2] The date of their marriage is unknown, but took place before 915.[3]

Alberic and Marozia had three children:[1]

  • Alberic II, aka Alberico, c. 914 - 954, m1. 936 to Alda of Italy (925-954), dau. of Ugo, King of Italy, m2. Hilda;
  • Constantino, d. after 14 Jan 945;
  • Sergio, d. after 14 Jan 945.

Alberic was possibly the father of John (Pope John XI), b.c. 906-911 (paternity disputed - see profile of Marozia ).


  • Alberic was in Italy with Charles II, "le Chauve", King of the West Franks and was named on an agreement dated Feb 876.[1]
  • He was a page to Guy III of Spoleto at the Battle on the Trebbia in 889.[3]
  • Installed himself as Marchese di Spoleto (aka Duke of Spoleto[4]) after killing Guido IV, Duke of Spoleto, in 897.[1]
  • He became Margrave of Camerino,[4] and as early as 897 had the title of Marchio.[3]
  • Secured the succession of Pope Sergius III in 904 together with Theophylact I,[2] his future father-in-law.
  • When he married Marozia he received the title of "princeps," Prince of Rome.[5]
  • He lead the armies of Spoleto and Camerino in the Christian League which defeated the Saracens at the Battle of the Garigliano in Jun 915,[6] after which he received appointment as "consul of the Romans" in 917.[3]
  • It is likely that after the death of the Emperor Berengar, Alberic became a tyrant, seizing the Roman government until he was expelled from Rome by Pope John X.[3]
  • He was murdered in his fortress at Orte/Horta, the revolt being led by Peter, the brother of John X,[3] probably about 924-926, but the exact date is unknown.
