Background

The Treaty of Kars translated the earlier Moscow understanding between Bolshevik Russia and Kemalist Turkey into a regional settlement signed by Soviet Armenia, Soviet Azerbaijan and Soviet Georgia. It came after the collapse of the First Republic of Armenia, the Turkish nationalist victory in the east, and the Soviet need for stable relations with Ankara.

The treaty

Signed on 13 October 1921, Kars confirmed the loss of Kars and Ardahan to Turkey. It also fixed Nakhichevan as an autonomous territory under the protection of Soviet Azerbaijan, with Turkey given a protective interest. That clause remains central because it explains why Nakhichevan is legally attached to Azerbaijan despite being separated from it by Armenian territory.

Aftermath and politics

For Armenia, Kars was the legal burial of the expansive promises of Sèvres. For Turkey, it secured the eastern frontier of the republic-to-be. For Azerbaijan, it anchored Nakhichevan. The settlement also intensified the significance of Zangezur, which became the strip preventing territorial contiguity between Azerbaijan proper and Nakhichevan.

Contemporary arguments over the Zangezur Corridor still orbit Kars. Azerbaijan and Turkey frame east-west connectivity as a corrective to geographic separation; Armenia frames extraterritorial corridor language as an attack on sovereignty contested. Kars did not create that dispute, but it made its map durable editorial.
