Kyrgyz Khaganate
The Kyrgyz Khaganate (also Yenisei Kyrgyz Khaganate or Kirghiz Khaganate) was a Turkic khaganate centered in southern Siberia. After the defeat of the Uyghur Khaganate in the hands of the Kyrgyz in 840, they gained political prestige and, for a short period until the mid-10th century (c. 925), established a nominal supremacy on the steppe.
