Ottoman Greeks (Greek: Ρωμιοί, romanized: Romioi; Turkish: Osmanlı Rumları) were ethnic Greeks who lived in the Ottoman Empire (1299–1922), much of which is in modern Turkey. 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). There were also sizeable Greek communities elsewhere in the Ottoman Balkans, 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.
