地处叶尼塞河上游的黠戛斯,汉代就见诸汉文史册,具有悠久的历史。8世纪初形成汗国,9世纪中期,它击溃漠北回鹘汗国。不仅结束了突厥语族在蒙古高原的统治,也为蒙古语族各部的兴起与发展创造了契机,从而改变了蒙古高原与中亚的政治格局。
Kirguises, which was located on the upstream of Yenisei River and had a long history, has been recorded in historical literature since the Han Dynasty. It formed a khanate at the beginning of the 8th century and defeated Uighur Khanate in northern Mongolia in the middle of the 9thcentury. It not only ended the rule of the Turkic tribes over Mongolian Plateau but also provided an opportunity for the rise and development of different Mongolian tribes. Thus, it changed the political structure of Mongolian Plateau and the Mid Asia.
