Treaty of Moscow
Just after the Soviet invasion of Armenia in November 1920, the Soviet Azerbaijani leader Nariman Narimanov declared that "the old borders between Armenia and Azerbaijan are declared null and void. Mountainous Karabagh, Zangezur, and Nakhichevan are recognized as integral parts of the Socialist Republic of Armenia." Despite these assurances, both Nakhichevan and Karabakh were kept under Azerbaijani control for another eight months. On 16 March 1921, Soviet Russia and the Government of the Grand National Assembly signed the Treaty of Moscow. By this treaty, Kars and Ardahan were ceded to Turkey, and Nakhichevan was put under "protectorate" of Azerbaijan. The Treaty of Kars was signed between the Grand National Assembly Government on one side and Armenian SSR, Georgian SSR and Azerbaijan SSR on the other, reaffirming the Treaty of Moscow.
