Kasimov (Russian: Каси́мов; Tatar: Касыйм;,[7] Ханкирмән Latinized : Kasıym, Hankirmən,[8] historically Gorodets Meshchyorsky, Novy Nizovoy) is a town in Ryazan Oblast, Russia, located on the left bank of the Oka River.

The town was founded in 1152 by the Vladimir-Suzdal ruler Yuri Dolgorukiy as Grodets, then Gorodets Meschyorsky (Городец Мещёрский).

[citation needed] It was included in the Mishar Yurt division of the Golden Horde, but then was sold to Muscovy.

After the Battle of Suzdal in 1445 (in which Grand Duke Vasily II was taken prisoner), the Meschyora lands were given to Oluğ Möxämmäd, Khan of Kazan Khanate as a ransom for the sovereign's life.

[3] In the 17th century, the town was separated into three parts: Historical buildings: Media related to Kasimov at Wikimedia Commons
