The Treaty of Moscow or Treaty of Brotherhood was a friendship treaty between the Grand National Assembly of Turkey (TBMM) under the leadership of Mustafa Kemal Atatürk and Bolshevist Russia under the leadership of Vladimir Lenin, signed on 16 March 1921. Neither the Republic of Turkey, nor the Soviet Union was established at the time; the internationally recognized Turkish government at the time was that of sultan Mehmed VI, which was no party to the Treaty of Moscow and which had earlier signed the Treaty of Sèvres that had been repudiated by the Kemalists.
