Turkic Khaganate
The Yenisei Kyrgyz rose from their homeland in the Yenisei River basin of Siberia to destroy the Uyghur Khaganate in 840 AD — a feat that earned their ruler formal recognition from the Tang dynasty as the supreme steppe Qaghan. The period of their dominance, known as the 'Kyrgyz Great Power Era,' was brief but historically significant as the final chapter of the pre-Mongol steppe succession.

The Kyrgyz Great Power Era ended not with a decisive military defeat but with a gradual withdrawal back toward the Yenisei homeland as the Khitan tribal confederation rose to dominance on the eastern steppe.

Faced the rising power of the Khitans under Abaoji, who would found the Liao dynasty in 916 AD; the Kyrgyz presence on the Mongolian steppe progressively diminished as Khitan military power expanded from Manchuria westward
