The Uighur Khaganate was a state established in the 8th century in Central Asia, primarily by the Uighur people. It emerged after the decline of the Turkic Khaganate and became a significant power in the region, controlling trade routes and engaging in cultural exchanges with neighboring empires. The khaganate lasted until the 840s when it was overthrown by the Kyrgyz. The Uighurs then migrated to the region of present-day Xinjiang in China, where they continued to influence the culture and politics of the area. The Uighur Khaganate played a crucial role in the history of Central Asia.
