Alcek or Alzeco was allegedly a son of Kubrat and led the Bulgars to Ravenna that later settled in the villages of Gallo Matese, Sepino, Boiano and Isernia in the Matese mountains of southern Italy.
After the collapse of Old Great Bulgaria, some of the Bulgars, led by Alzeco, thought to be a son of Kubrat, settled in the lands of the Longobard Kingdom. Paul the Deacon places a settlement in his history of the migration of the Bulgars in the area of the Duchy of Benevento. Under the leadership of Alzeco, the Bulgars (called "Vulgars" by Paul) came to Italy in Benevento, where they settled in the Molise region.[1]
