In combination with the 1813 Treaty of Gulistan, some authors have claimed that the two resulting Iranian territorial cessions separated the Azerbaijani people and the Talysh people from their brethren in Iran.[16][17][18] Following the two treaties, the formerly Iranian territories came under the Russian, and later the Soviet control for approximately 180 years, and Dagestan remains a constituent republic within the Russian Federation to this day. Comprising most of the territory ceded in Gullistan and Turkmenchay treaties, three separate nations would gain independence following the dissolution of the Soviet Union in 1991: Georgia, Azerbaijan and Armenia.
