Chakkar
Chakkar 1. A Mongol tribe, Ili Valley, Kulja, originally from the N.W. frontier of China. 2. A branch of the Khalkas (Eastern Mongolians), S.E. of the Gobi desert towards Kalgan. Their territory is nearly 500 miles long east and west, by 130 broad. In recent times they have become much mixed with the Chinese, whom they now resemble in features, "having generally a drawn or angular rather than a. flat or round face" (Prjevalsky, Mongolia, i: p. 33). The Chakkars form eight Koshongs ("banners") under hereditary princes.
