The book is devoted to one of the most difficult problems of the early medieval history of Azerbaijan, associated with the process of long-term interaction of the early Turkic (Hunnic) ethnic communities of the North Caucasus with Albania. It covers the period (II-VI centuries), which had special significance and the history of the Azerbaijani and other peoples of the region, when they faced a powerful wave of tribal movements of the steppe peoples, which played an important role in the formation of modern ethnic communities.
