Pontic Greeks
Between 1461 and the second Russo-Turkish War of 1828–29, Pontic Greeks from northeastern Anatolia migrated as refugees or economic migrants (especially miners and livestock breeders) into nearby Armenia or Georgia, where they came to form a nucleus of Pontic Greeks which increased in size with the addition of each wave of refugees and migrants until these eastern Pontic Greek communities of the South Caucasus region came to define themselves as Caucasian Greeks.
