Московский договор
The treaty was the successor treaty to the March 1921 Treaty of Moscow. Most of the territories ceded to Turkey in the treaty were acquired by Imperial Russia from the Ottoman Empire during the Russo-Turkish War of 1877–1878. The only exception was the Surmali region, which had been part of the Erivan Khanate of Iran before it was annexed by Russia in the Treaty of Turkmenchay after the Russo-Persian War of 1826–28.
