Kuber

Terracotta tile with the Latin inscription "BOLGAR" and "SCLAVIGI" found in Vinica, North Macedonia, which according to some interpretations depicts a battle scene from the late 7th century between Kuber's Bulgars and Slavs.^[1][2]

Kuber^[3] (also Kouber or Kuver) was a Bulgar leader who, according to the Miracles of Saint Demetrius, liberated a mixed Bulgar and Byzantine Christian population in the 670s, whose ancestors had been transferred from the Eastern Roman Empire to the Syrmia region in Pannonia by the Avars 60 years earlier.^[4][5] According to a scholarly theory, he was a son of Kubrat, brother of Khan Asparukh and member of the Dulo clan.
