Some Azerbaijanis of the Republic of Azerbaijan are believed to be descended from the inhabitants of Caucasian Albania, an ancient country located in the eastern Caucasus region, and various Iranian peoples which settled the region. They claim there is evidence that, due to repeated invasions and migrations, the aboriginal Caucasian population may have gradually been culturally and linguistically assimilated, first by Iranian peoples, such as the Persians, and later by the Oghuz Turks. Considerable information has been learned about the Caucasian Albanians, including their language, history, early conversion to Christianity, and relations with the Armenians and Georgians, under whose strong religious and cultural influence the Caucasian Albanians came in the coming centuries.
