Qasim Khanate

The Qasim Khanate (also called Qasimov, Kasimov, or Kasim), also known as the Tsardom of Kasimov (Russian: Касимовское царство), was a Tatar-ruled khanate which existed from 1452 until 1681 on the territory of the Russian state. It was located within modern-day Ryazan Oblast with its capital at Kasimov, in the middle course of the Oka River. It was initially in the sphere of influence of the Grand Principality of Moscow and then was dependent on the Tsardom of Russia. The khanate was established in the lands which Grand Prince Vasily II of Moscow (r. 1425–1462) presented in 1452 to the Kazan prince Qasim Khan (d. 1469), son of the first Kazan khan Olug Moxammat.
