Batbayan
Ruler of Bulgars
Batbayan ruled the Khazarian Bulgars from 667 to 690 CE.[1][2] Theophanes and Nicephorus record his rule after the Khazars defeated the Bulgars and Old Great Bulgaria disintegrated in 668 CE.[3]
There is a scholarly theory that he may have been the same person as Bezmer[4] of the Nominalia of the Bulgarian khans who may have been also the first son of Kubrat.[5] He was a member of the Dulo clan, who after Kubrat's death in the mid-7th century ruled Old Great Bulgaria, but his rule lasted only three years.[6] Kevin Alan Brook calls him Bayan.[7] Batbayan would subsequently have ruled the Bulgars as a subject of the Khazar Khagan.
