There is a scholarly theory that he may have been the same person as BezmerBoris Zhivkov, Khazaria in the Ninth and Tenth Centuries, East Central and Eastern Europe in the Middle Ages, 450-1450, BRILL, 2015, , p. 228. of the Nominalia of the Bulgarian khans who may have been also the first son of Kubrat.Florin Curta, Roman Kovalev as ed., "'The' Other Europe in the Middle Ages: Avars, Bulgars, Khazars and Cumans", Volume 2 of East Central and Eastern Europe in the Middle Ages, 450 - 1450, BRILL, 2008, , p. 152. 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.Vasil Gyuzelev, The Proto-Bulgarians: Pre-history of Asparouhian Bulgaria, Sofia Press, 1979, p. 29.
