Galdan Boshugtu Khan
Dzungar power reached its height in the second half of the 17th century, when Galdan Boshugtu Khan repeatedly intervened in the affairs of the Kazakhs to the west, but it was completely destroyed by the Qing Empire about 1757–1759. It has played an important part in the history of Mongolia and the great migrations of Mongolian stems westward. Its widest limit included Kashgar, Yarkand, Khotan, the whole region of the Tian Shan, and the greater proportion of that part of Central Asia which extends from 35° to 50° N and from 72° to 97° E.
