The Kyrgyz Khaganate was a Turkic empire that existed between the early 6th and 13th centuries. It ruled over the Yenisei Kyrgyz people, who had been located in southern Siberia since the 6th century. By the 9th century, the Kyrgyz had asserted dominance over the Uyghurs who had previously ruled the Kyrgyz. The empire was established as a khaganate from 539 to 1218, lasting 679 years. The khaganate's territory at its height would briefly include parts of modern-day China, Kazakhstan, Kyrgyzstan, Mongolia, and Russia. After the 10th century, there was little information on the Yenisei Kyrgyz. It is believed the khaganate had survived in its traditional homeland until 1207.
