Muhammad Shaybani
The ruler of the Uzbek ulus Abu'l-Khayr Khan (1428-1468) had eleven sons, one of whom was Budaq Sultan, the father of Shaybani Khan. Shaybani Khan's mother's name was Aq Quzi Begum. Through his mother, Muhammad Shaybani was therefore the cousin of Janibek's son Kasym Khan, the latter of whom ultimately conquered most of Shaybani's territory to expand the Kazakh Khanate.
