Dastan about Uraz-Muhammad Khan from the work of Kadyr-Ali bek as a source about the clans of the tatars of Kasimov

Research objective: To reveal information about the ruling clans in the Kasimov Khanate based on information from the dastan about Uraz-Muhammad Khan in the work of Kadyr-Ali bek. Research materials: The image of the throne in the dastan about Uraz-Muhammad is the only source about the names of clans among the beks of the Kasimov Khanate. The research uses acts and documents of management and record keeping, legends of the Tatars, genealogical lists, writings of eastern origin, and the results of genetic studies of the Y-chromosome of the beks’ descendants. Results: This article presents the results of long-term research in which, among the Kasimov Tatars, Karachi-beks who participated in the ceremony of enthroning Uraz-Muhammad to the Khan’s throne in 1600 were identified. Their family trees and origins have been explicated. Considering that the Kasimov Karachi-beks were representatives of the well-known Horde clans, we accordingly received an idea of the origin of some of the most powerful aristocratic non-Chingisid clans of the Jochid Ulus era. In addition, some plots on the history of the Meshchera Tatars associated with representatives of the studied clans are considered.
