Treaty of Ganja
The Treaty of Ganja was concluded between the Russian Empire and Iran on 10 March 1735 near the city of Ganja (present-day Azerbaijan). The treaty established a defensive alliance against the Ottoman Empire, which had suffered a defeat in the Ottoman-Persian war of 1730-35. The Russian government agreed to return the remaining territories in the North Caucasus and South Caucasus, including Derbend and Baku, that had been conquered by Peter I in the 1720s. The treaty also confirmed the provisions of the 1732 Treaty of Resht whereby Russia renounced its claim to Gilan, Mazandaran, and Astrabad, and Iran recognized Vakhtang VI, a pro-Russian Georgian king-in-exile. The treaty provided for Russia a diplomatic advantage in a simmering war with the Ottomans and for the Iranian ruler Nader Shah a respite on the western frontier of his empire.
