Avar Khaganate
Following Khan Kubrat's death or a few years later in the time of Bezmer, the empire was dissolved into 5 branches. Two of them (led by Batbayan and Kotrag) were subdued by the emerging Khazar Empire, while the third one led by Asparukh established the Danube Bulgar Empire and stabilized it by the victory at the battle of Ongal. The fourth folk moved to Ravenna while the fifth one, led by Kuber moved into the Avar Khaganate.
