Kalmyk Khanate
The Kalmyk Khanate was an Oirat Mongol khanate on the Eurasian steppe. It extended over modern Kalmykia and surrounding areas in the North Caucasus, including Stavropol and Astrakhan. During their independence, the Kalmyks both raided and allied with Russia in turn, engaging in numerous military expeditions against the Crimean Tatars, the Ottoman Empire, neighboring Muslim tribes, and the highlanders of the North Caucasus. The Khanate was annexed by the Russian Empire in 1771.
