jul 3, 840 - Fall of Uyghur Khaganate

Description:

In 840, 1 of 9 Uyghur ministers, Kulug Bagha, rival of Kurebir, fled to the Yenisei Kyrgyz and invited them to invade from the north. With a force of around 80,000 horsemen, they sacked the Uyghur capital at Ordu-Baliq, razing it to the ground. The Kyrgyz captured the Uyghur Khagan, Kürebir , and promptly beheaded him. They went on to destroy other cities throughout the Uyghur empire, burning them to the ground. The Uyghurs fled in two groups.
