Idel-Ural (Tatar: Идел-Урал, Russian: Идель-Урал) literally Volga-Ural is a historical region in Eastern Europe, in what is today Russia. The name literally means Volga-Urals in the Tatar language. The frequently used Russian variant is Volgo-Uralye (Russian: Волго-Уралье). The term Idel-Ural is often used to designate 6 republics of Russia of this region: Bashkortostan, Chuvashia, Mari El, Mordovia, Tatarstan, and Udmurtia, especially in Tatar-language literature or in the context of minority languages.
Before being conquered by the Tsardom of Russia in the 16th century, the region was dominated by native Uralic tribes and a succession of Turkic empires, such as Volga Bulgaria, the Khazars, the Golden Horde, and the Khanate of Kazan.
