Terek River
In 1783, Erekle II of Khartli-Kakheti agreed to become a vassal state of the Russian Empire in return for Russian protection. This was formalised in the Treaty of Georgievsk on 24 July 1783. Persia still considered Khartli-Kakheti to be its vassal state. Following the signature of the Treaty of Georgievsk, the Vladikavkaz fortress was built on the Terek River.
