The Persian Expedition of Catherine the Great, alongside the Persian Expedition of Peter the Great, was one of the Russo-Persian Wars of the 18th century which did not entail any lasting consequences for either belligerent. 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. The kingdom of Georgia 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.
