The Khanate of Kazan (; Russian: Казанское ханство, tr: Kazanskoye khanstvo) was a medieval Bulgarian-Tatar Turkic state which occupied the territory of former Volga Bulgaria between 1438 and 1552. Its khans were the patrilineal descendants of Tugh Temür, the thirteenth son of Jochi and grandson of Genghis Khan. The khanate covered contemporary Tatarstan, Mari El, Chuvashia, Mordovia, parts of Udmurtia and Bashkortostan; its capital was the city of Kazan. It was one of the successor states of the Golden Horde, and it came to an end when it was conquered by the Tsardom of Russia.
