Турки-османы
Ottoman Turks began to settle in Azerbaijan when the region came under the rule of the Ottoman Empire between 1578 and 1603 and then again in the second Ottoman conquest of 1724 until the end of World War I in 1918. The First All-Union Census of the Soviet Union in 1926 recorded 8,570 Ottoman Turks living in the Soviet Union. The Ottoman Turks are no longer listed separately in the census; it is presumed that those who were living in Azerbaijan have either been assimilated into Azerbaijani society or have left the country. Approximately 19,000 descendants of the Ottoman Turks (not including the Meskhetian Turks) are estimated to be living in Azerbaijan.
