The Khanate of Kazan was a Tatar state that existed from 1438 to 1552, located in what is now central Russia. It emerged after the decline of the Golden Horde and became a significant center of trade and culture. The khanate was known for its diverse population, including Tatars, Russians, and other ethnic groups. In 1552, the Khanate of Kazan fell to the forces of Ivan the Terrible, marking a key event in the expansion of the Tsardom of Russia. This conquest led to the incorporation of Kazan into Russia, significantly impacting the region's political and cultural landscape.
