Erivan Khanate
The treaty was signed on 10 February 1828 in Torkamanchay, Iran. It made Persia cede the control of several areas in the South Caucasus to Russia: the Erivan Khanate, the Nakhchivan Khanate and the remainder of the Talysh Khanate. The boundary between Russian and Persia was set at the Aras River. The territories are now Armenia, the south of Azerbaijan, Nakhchivan and Iğdır Province (now part of Turkey).
