The Shaybanids are the patrilineal descendants of Shayban (Shiban), the fifth son of Jochi and grandson of Genghis Khan. Until the mid-14th century, they acknowledged the authority of the descendants of Batu Khan and Orda Khan, such as Uzbeg Khan. The Shaybanid horde was converted to Islam in 1282 and gradually assumed the name of Uzbeks. As the lineages of Batu and Orda died out in the course of the great civil wars of the 14th century, the Shaybanids under Abu'l-Khayr Khan declared themselves the only legitimate successors to Jochi and put forward claims to the whole of his enormous ulus, which included parts of Siberia and Kazakhstan. Their rivals were the Timurids, who claimed descent from Jochi's thirteenth son by a concubine. Several decades of strife left the Timurids in control of the Great Horde and its successor states in Europe, namely, the Khanates of Kazan, Astrakhan, and . However, the Shaybanids under Muhammad Shaybani were able to wrest control of Samarkand, Bukhara and (for a time) Herat from the Timurids, establishing the Shaybanid dynasty as rulers of the independent Khanates of Bukhoro and Khwarezm (Khiva).
