Treaty of Moscow
Under the 1921 Treaty of Moscow, the two governments undertook to establish friendly relations between the countries. Under Article II, Turkey ceded Batum and the adjacent area north of the village of Sarp to Soviet Georgia (Kars Oblast went to Turkey). Article III instituted an autonomous Nakhchivan oblast under Soviet Azerbaijan's protectorate. Article V had the parties agree to delegate the final elaboration of the status of the Black Sea and the Turkish Straits to a future conference of delegates of the littoral states if the "full sovereignty" and security of Turkey and "her capital city of Constantinople" were not injured. The Treaty of Moscow was followed by an identical Treaty of Kars signed in October 1921 by the Kemalists with Soviet Armenia, Soviet Azerbaijan and Soviet Georgia, which formed part of the Soviet Union after the December 1922 Treaty on the Creation of the Soviet Union.
