Azerbaijan–Turkey relations
bilateral relations between Azerbaijan and Turkey

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. Since then, Turkey has been a staunch supporter of Azerbaijan in its efforts to consolidate its independence, preserve its territorial integrity over the Nagorno-Karabakh region, and realize its economic potential arising from the rich natural resources of the Caspian Sea. The two countries share a 17 kilometres (11 mi) long international borderline, with the Aras River separating Turkey from the Nakhchivan exclave of Azerbaijan.
History
Azerbaijan Soviet Socialist Republic period
After the signing of the Treaty of Kars, a diplomatic mission of the Azerbaijan Soviet Socialist Republic was sent to Turkey. From 1921 to 1922, the diplomatic representative of the Azerbaijan Soviet Socialist Republic and the Transcaucasian Socialist Federative Soviet Republic to Turkey was Ibrahim Abilov.
Since 1991
First Nagorno-Karabakh War
When the First Nagorno-Karabakh War began, Turkey fully supported Azerbaijan, particularly during the presidency of Azerbaijani President Abulfaz Elchibey. After the Kalbajar District came under the control of the Armenian Armed Forces, Turkey expressed its support for Azerbaijan at an emergency meeting of the United Nations Security Council held on April 6, 1993. However, the Security Council did not accept Turkey’s proposed wording describing the situation as “Armenian aggression against the sovereign Republic of Azerbaijan.” Instead, the adopted resolution merely expressed serious concern over the escalation of hostilities in the Nagorno-Karabakh conflict and did not mention Armenian aggression.
In May 1992, Armenian armed forces attacked the Nakhchivan Autonomous Republic, raising the possibility of Turkish intervention in the war.
