Эриванское ханство
Things changed when Aleksey Yermolov took office as the new Russian commander-in-chief in the Caucasus, in 1816. A staunch Russian imperialist, Yermolov was committed to bringing the entire Caucasus under the Russian sway. He wanted to establish the Aras river as the border between Iran and Russia at all costs, and was therefore determined to conquer the last remaining khanates under Iranian rule; the Erivan Khanate and the Nakchivan Khanate.
