The last steppe empire to emerge was that of the Dzungars who conquered much of East Turkestan and Mongolia. However, in a sign of the changed times they proved unable to match the Chinese and were decisively defeated by the forces of the Qing Dynasty. In the 18th century the Qing emperors, themselves originally from the far eastern edge of the steppe, campaigned in the west and in Mongolia, with the Qianlong Emperor taking control of Xinjiang in 1758. The Mongol threat was overcome and much of Inner Mongolia was annexed to China.
