Erivan Governorate
During the 1st half of the 19th century, following the Russo-Persian War of 1826-28 and the resulting Treaty of Turkmenchay signed in 1828, Vayots Dzor passed from Iranian to Russian rule. In the same year the territory passed to the Russians, it was incorporated into the newly-established Armenian Oblast. In 1849, the Erivan Governorate was founded including Vayots Dzor, while in 1870, the governorate was further divided into uyezds. Consequently, Vayots Dzor became part of the Sharur-Daralagezsky Uyezd of Erivan Governorate.
