Khanate Of Erevan
The Erivan Khanate (Persian: خانات ایروان — Khānāt-e Īravān; Armenian: Երևանի խանություն Yerevani khanut'yun; Azerbaijani: İrəvan xanlığı — ایروان جانلیغی) also known as Čoḵūr Saʿd, was a khanate that was established in Safavid Persia in the 18th century. It covered an area of roughly 19,500 km2, and corresponded to most of present-day central Armenia, most of the Iğdır Province of present-day Turkey, and the Sharur and Sadarak rayons of the Nakhchivan Autonomous Republic of present-day Azerbaijan.
As a result of the Persian defeat in the last Russo-Persian War, it was ceded to the Russian Empire in accordance with the 1828 Treaty of Turkmenchay. Immediately following this, the territories of the former Erivan Khanate and the Nakhichevan Khanate were joined to form the "Armenian Oblast" of the Russian Empire.
