Seafaring Ionian Greeks settled around the southern shores of the Black Sea starting around 800 BC, later expanding to coastal regions of modern Romania, Russia, Bulgaria and Ukraine.

They were joined in the region by later waves of Greeks in the Hellenistic, Roman, and Byzantine period, ranging from traders, scholars, churchmen, mercenaries, or refugees from elsewhere in Anatolia or the southern Balkans.

The largest communities can be found in Alaverdi and Yerevan,[2] followed by Vanadzor, Gyumri, Stepanavan, Hankavan and Noyemberyan.

Yaghdan in Lori Province has been described as the last remaining Greek village in Armenia.

A certain layer is occupied by the migrants from Trabzon and Kars region in the 19th – 20th century.
