Kuber

Kuber (also Kouber or Kuver) was a Bulgar leader who according to the Miracles of Saint Demetrius led in the 670s, a mixed Bulgar and Byzantine Christian population, whose ancestors had been transferred from the Eastern Roman Empire to the Syrmia region in Pannonia by the Avars 60 years earlier. According to a scholarly theory, he was the son of Kubrat, brother of Khan Asparukh and member of the Dulo clan.
