The Caucasus Greeks (Greek: Έλληνες του Καυκάσου or more commonly Καυκάσιοι Έλληνες, Turkish: Kafkas Rum), also known as the Greeks of Transcaucasia and Russian Asia Minor, are the ethnic Greeks of the North Caucasus and Transcaucasia in what is now southwestern Russia, Georgia, and northeastern Turkey. These specifically include the Pontic Greeks, though they today span a much wider region including the Russian north Caucasus, and the former Russian Caucasus provinces of the Batum Oblast and the Kars Oblast (the so-called Russian Asia Minor), now in north-eastern Turkey and Adjara in Georgia.
Greek people migrated into these areas well before the Christian/Byzantine era. Traders, Christian Orthodox scholars/clerics, refugees, mercenaries, and those who had backed the wrong side in the many civil wars and periods of political in-fighting in the Classical/Hellenistic and Late Roman/Byzantine periods, were especially represented among those who migrated. One notable example is the 7th-century Greek Bishop Cyrus of Alexandria, originally from Phasis in present-day Georgia. Greek settlers in the Caucasus generally became assimilated into the indigenous population, particularly in Georgia, where Byzantine Greeks shared a common Christian Orthodox faith and heritage with the natives.
