 Whilst Priscus' accounts provide some information about the ethno-political situation in the Don-Kuban-Volga region after the demise of the Huns, no unequivocal conclusions can be reached.Denis Sinor has argued that whoever the "Avars" referred to by Priscus were, they differed from the Avars who appear a century later, during the time of Justinian (who reigned from 527 to 565).The next author to discuss the Avars, Menander Protector, appeared during the 6th century, and wrote of Göktürk embassies to Constantinople in 565 and 568 AD.
