Zangezur

Zangezur (, ) is a historical and geographical region in Eastern Armenia on the slopes of the Zangezur Mountains which largely corresponds to the Syunik Province of Armenia and East Zangezur Economic Region of Azerbaijan. It was ceded to Russia by Qajar Iran according to the Treaty of Gulistan in 1813. In Soviet times, the territory of Zangezur comprised the Goris, Kapan, Meghri, and Sisian districts of the Armenian SSR and the Lachin, Qubadli, and Zangilan districts of the Azerbaijani SSR. In 1995, the Armenian districts within historical Zangezur were merged to form the Syunik Province. In Azerbaijan, the corresponding districts, while retaining their administrative status, became part of the East Zangezur Economic Region in 2021.
