Following the Russo-Persian War of 1804–13, Syunik -along with the rest of Karabakh Khanate- passed into Imperial Russian possession, officially signed in the Treaty of Gulistan in 1813. The khanate was abolished by the Russian government in 1822. The region was divided between the Erivan Governorate, and Baku Governorate (known as "Shemakha Governorate" until 1859). When the Elisabethpol Governorate was established in 1868, the region became part of the Zangezursky Uyezd, with its administration based in the town of Geryusy starting from 1870.
