Azerbaijan–Turkey relations

Azerbaijan–Turkey relations have been strong between the only two predominantly Turkic countries located west of the Caspian Sea and east of the Mediterranean Sea. Former Azerbaijani president Heydar Aliyev often described the two as being "one nation, two states." Turkey was one of the first countries to recognize Azerbaijan's independence on 4 June 1918 (Treaty of Batum) and the first to recognize Azerbaijan's restoration of independence from the Soviet Union in 1991.
