The article discusses the important issues of the history of the ancient population of the Caucasus and the Middle East. It highlights the question of historical and cultural content of the names taken from the written sources created by peoples lived in this region including the following: the Kaskians, the Achaeans, the Pelasgians, the Geniokhs, the Abeshla, the Zikhs, and others. The research unveils the internal connection of these ethnonyms with each other, as well as with other ancient, medieval and modern ethnic terms of the Caucasus and adjacent territories. It suggests the possibility of the broad meaning of the ethnonym Geniokhs, resulted from the connections of this ethnos with the ancient tribes of the Abkhaz-Agygei population of the North-Eastern Anatolia, the Pre-Caucasian region and the Eastern Black Sea region. The.lose relations between these areas developed in the ancient times, promoting the exchange of achievements of material and spiritual culture, the formation of ethno-contact zones and migration.
