Urus, the eighth Khan of the White Horde, and a disputable Khan of the Blue Horde, is a direct descendant of Genghis Khan through his eldest grandson, Orda.

Little, if anything is known of Urus' life except that he was indeed a very powerful Khan, confident enough to make war on the great Timur to demand the extradition of his nephew Tokhtamysh (Tuqtamish), an ungrateful pensioner who had tried to overthrow him in 1376 and then fled to Timur.

Urus, driven back to the steppe by Timur in 1377, had died shortly afterwards, and Timur proclaims as Khan his protégé Tokhtamysh, who has also outlived both of Urus’s sons.

Timur thus takes effective control of the White Horde, having conquered three-quarters of their land in five years.
