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.

Ottoman Greeks (Greek: Ρωμιοί, romanized: Romioi; Turkish: Osmanlı Rumları) were ethnic Greeks who lived in the Ottoman Empire (1299–1922), a large part of which is in modern Turkey, Greece and the rest of the Balkans. Ottoman Greeks were Greek Orthodox Christians who belonged to the Rum Millet (Millet-i Rum). They were concentrated in eastern Thrace (especially in and around Constantinople), and western, central, and northeastern Anatolia (especially in Smyrna, Cappadocia, and Erzurum vilayet, respectively), in Ottoman Greece and other parts of the Ottoman Balkans, and in Ottoman Cyprus. There were also sizeable Greek communities elsewhere in the Ottoman Armenia, Ottoman Syria and the Ottoman Caucasus, including in what, between 1878 and 1917, made up the Russian Caucasus province of Kars Oblast, in which Pontic Greeks, northeastern Anatolian Greeks, and Caucasus Greeks who had collaborated with the Russian Imperial Army in the Russo-Turkish War of 1828–1829 were settled in over 70 villages, as part of official Russian policy to re-populate with Orthodox Christians an area that was traditionally made up of Ottoman Muslims and Armenians.

This article details the geographical distribution of Russian speakers. After the dissolution of the Soviet Union in 1991, the status of the Russian language often became a matter of controversy. Some Post-Soviet states adopted policies of derussification aimed at reversing former trends of Russification, while Belarus under Alexander Lukashenko and the Russian Federation under Vladimir Putin reintroduced Russification policies in the 1990s and 2000s, respectively.

After the collapse of the Russian Empire in 1917, derussification occurred in the newly-independent Poland, Estonia, Latvia, Lithuania and the Kars Oblast, the last of which became part of Turkey.

Ottoman Greeks (Greek: Ρωμιοί, romanized: Romioi; Turkish: Osmanlı Rumları) were ethnic Greeks who lived in the Ottoman Empire (1299–1922), a large part of which is in modern Turkey, Greece and the rest of the Balkans. Ottoman Greeks were Greek Orthodox Christians who belonged to the Rum Millet (Millet-i Rum). They were concentrated in eastern Thrace (especially in and around Constantinople), and western, central, and northeastern Anatolia (especially in Aidin vilayet, Hüdavendigâr vilayet, Konya vilayet, and Trebizond vilayet, respectively), in Ottoman Greece and other parts of the Ottoman Balkans, and in Ottoman Cyprus. There were also sizeable Greek communities elsewhere in the Ottoman Armenia, Ottoman Syria and the Ottoman Caucasus, including in what, between 1878 and 1917, made up the Russian Caucasus province of Kars Oblast, in which Pontic Greeks, northeastern Anatolian Greeks, and Caucasus Greeks who had collaborated with the Russian Imperial Army in the Russo-Turkish War of 1828–1829 were settled in over 70 villages, as part of official Russian policy to re-populate with Orthodox Christians an area that was traditionally made up of Ottoman Muslims and Armenians.

Tiflis Governorate was a province (guberniya) of the Caucasus Viceroyalty of the Russian Empire with its administrative centre in Tiflis (present-day Tbilisi). In 1897, it constituted 44,607 square kilometres (17,223 sq mi) in area and had a population of 1,051,032 inhabitants. Tiflis Governorate bordered Elizavetpol Governorate to the southeast, Erivan Governorate to the south, Kars Oblast to the southwest, Batum Oblast to the west, Kutaisi Governorate to the northwest, Terek Oblast to the north, Dagestan Oblast to the northeast, and after 1905, the Zakatal Okrug to the east. The governorate covered areas of central and southeastern Georgia, the partially recognised state of South Ossetia, most of the Lori Province of Armenia, small parts of northwestern Azerbaijan, and a minuscule southern part of Ingushetia of Russia.

Kağızman (Kurdish: Qaxizman), formerly Kaghzvan (Armenian: Կաղզուան), is a town in Kars Province in the Eastern Anatolia region of Turkey. It is the seat of Kağızman District. Its population is 21,130 (2022).

The current mayor is Okan Daştan (State Appointment). The town was the administrative center of the Kagizman Okrug of the Kars Oblast until 1918.

The Erivan Governorate was a province (guberniya) of the Caucasus Viceroyalty of the Russian Empire, with its centеr in Erivan (present-day Yerevan). Its area was 27,830 sq. kilometеrs, roughly corresponding to what is now most of central Armenia, the Iğdır Province of Turkey, and the Nakhchivan exclave of Azerbaijan. At the end of the 19th century, it bordered the Tiflis Governorate to the north, the Elizavetpol Governorate to the east, the Kars Oblast to the west, and Persia and the Ottoman Empire to the south. Mount Ararat and the fertile Ararat Valley were included in the center of the province.

In 1828, the khanates of Erivan and the Nakhichevan were annexed from Persia by the Russian Empire through the Treaty of Turkmenchay. The newly annexed territories were incorporated into a single administrative unit known as the Armenian Oblast. In 1849, the oblast was reorganized into a governorate.
