Treaty of Georgievsk
The last decades of the 18th century were marked by continual strife between rival claimants to the Peacock Throne. Catherine the Great of Russia took advantage of the disorder to consolidate her control over the weak polities of the Caucasus, which was, for swaths of it, an integral Persian domain. The kingdom of Georgia, a subject of the Persians for many centuries, became a Russian protectorate in 1783, when Erekle II signed the Treaty of Georgievsk, whereby the Empress promised to defend him in case of the Iranian attack. The shamkhals of Tarki followed the lead and accepted Russian protection three years later.
