Muhammad Shaybani
In the early 16th century, Ahmad and Mahmud decided to counter the growing power of the Uzbeks under Muhammad Shaybani. The two brothers united the forces and launched a campaign against the Uzbeks, but Muhammad Shaybani proved victorious in battle and took them both prisoner (Babur also was among his uncles' army and participated in this battle in Ferghana Valley, that had turned into disaster, but managed to flee south and hide in mountains with his mother, Kutluk Nigar Khanum, daughter of Yunus Khan, and few followers). They were soon released, but Ahmad died shortly afterwards, in 1503. He was succeeded in Uyghurstan by his eldest son Mansur Khan.
