This effectively allowed Qasim Khan to conquer all of modern Kazakhstan, much of modern-day Uzbekistan, and parts of southwestern Siberia, western China, and Kyrgyzstan.
The Kazakh Khanate consistently controlled of all of these lands until the 18th century, when they began suffering attacks from the Tsardom of Russia in the north, the Emirate of Bukhara to the south, and the Dzungars in the east.

Towards the end of his reign, Qasim built an alliance with the rising Timurid prince Babur, who shared a common enemy of Muhammad Shaybani with him.
