Kars Oblast
The treaty created a new boundary between Turkey and Soviet Armenia, defined by the Akhurian (Arpachay) and Aras Rivers. Turkey obtained the territory of the former Kars Oblast of the Russian Empire, including the cities of Kars, Ardahan, and Olti, Lake Childir and the ruins of Ani. From the former Erivan Governorate, it also obtained the Surmalinsky Uyezd (Surmali), with Mount Ararat, the salt mines of Kulp (Tuzluca), and the city of Igdyr, as well as the Aras corridor, a narrow strip of land between the Aras and Lower Karasu Rivers that had been part of the Erivansky Uyezd. In exchange Turkey agreed to cede to Soviet Armenia the district of Aqbaba, a small area around Lake Arpi inhabited by Karapapak Turks which had been part of the former Kars Oblast.
