Muhammad Shaybani
Abu'l-Khayr Khan died in 1468 (though some sources say 1469 or 1470). After Abu'l-Khayr Khan's death two separate lines of descent controlled the twin Uzbek states of Mawara al-Nahr and Khwarezm. In the first decade of the 16th century his grandson Muhammad Shaybani finally succeeded in the unification of the Uzbeks and established the short-lived Shaybanid Empire, centered in Samarkand.
