Most international scholars agree that it is extremely difficult to judge the ethnic identity of the various population segments due primarily to the fact that the terms "Abkhazia" and "Abkhazians" were used in a broad sense during this period—and for some while later—and covered, for all practical purposes, all the population of the kingdom, comprising both the Georgian (including also Mingrelians, Laz, and Svans with their distinct languages that are related to the Georgian language) and possible modern Abkhaz (Abasgoi, Apsilae, and Zygii) peoples. It seems likely that a significant (if not predominant) proportion of the Georgian-speaking population, combined with a drive of the Abkhazian kings to throw off the Byzantine political and cultural dominance, resulted in Georgian replacing Greek as the language of literacy and culture.
