The Shaybanids (Persian: سلسله شیبانیان) were a Persianized dynasty of Turco-Mongol origin in Central Asia. They were the patrilineal descendants of 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 Öz Beg Khan. The Shaybanid led grey horde, also known as the Uzbegs (Uzbeks), was converted to Islam in 1282. At its height, the khanate included parts of modern-day Afghanistan and parts of central Asia.
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 Timurid dynasty, 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 Crimea.
Under Abu'l-Khayr Khan (who led the Shaybanids from 1428 to 1468), the dynasty began consolidating disparate Ozbeg (Uzbek) tribes, first in the area around Tyumen and the Tura River and then down into the Syr Darya region. His grandson Muhammad Shaybani (ruled 1500-10), who gave his name to the Shaybanid dynasty, conquered Samarkand, Herat,Balkh and Bukhara, thus ending the Timurid dynasty and establishing the short-lived Shaybanid Empire. After his death at the hands of Shah Ismail I, he was followed successively by an uncle, a cousin, and a brother, whose Shaybanid descendants would rule the Khanate of Bukhara from 1505 until 1598 and the Khanate of Khwarezm (Khiva) from 1511 until 1695.
