The Greeks of Armenia are mainly descendants of the Pontic Greeks, who originally lived in the Pontic Mountains, along the shores of the Black Sea, and other parts of northeastern Anatolia. 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. The Pontic Greeks lived for thousands of years almost isolated from the Greek peninsula, retaining elements of the Ancient Greek language and making Pontic Greek unintelligible to most other modern Hellenic languages.
Several villages with a large proportion of ethnic Greek Armenians are found in areas along Armenia's northern border with Georgia, in the northern part of the Lori marz (province). The largest communities can be found in Alaverdi and Yerevan, followed by Vanadzor, Gyumri, Stepanavan, Hankavan and Noyemberyan. Ethnic Greeks in Armenia numbered around 1,800 to over 4,000. Their numbers have been greatly reduced since the end of the Soviet Union due to emigration for economic reasons to other former Soviet republics and to Greece. Greeks and Armenians also live together in mixed communities north of the Armenian border in Georgia - but there too numbers have been greatly reduced due to emigration. Yaghdan in Lori province has been described as the last remaining Greek village in Armenia.
Armenia’s Greeks, as in the whole of Transcaucasia, speak the Pontic dialect, an extension of the Ionic dialect of the ancient Greek language. A certain layer is occupied by the migrants from Trabzon and Kars region in the 19th – 20th century. (endoethnonym: ROMEYUS). All Armenia’s Greeks are fluent in both Armenian and Russian. The Greek population in Armenia today is about 6,000.
