Rebellion of Cao Qin

The Rebellion of Cao Qin () was a day-long uprising in the Ming dynasty capital of Beijing on August7, 1461, staged by Chinese general Cao Qin (; died 1461) and his Ming troops of Mongol and Han descent against the Tianshun Emperor (r. 1457–1464). Cao and his officers launched the insurrection out of fear of being persecuted by Tianshun. Tianshun had just gained back the throne from his half-brother the Jingtai Emperor, who rose to power during the 1449 Tumu Crisis.

The rebellion was a failure: three of Cao's brothers were killed during the ensuing battle, and Cao Qin was forced to commit suicide during a last stand against imperial troops storming his Beijing residential compound. The rebellion marked the high point in political tension over allowing Mongols to be employed in the Ming military command structure. Ming Chinese officials often made recompense with Mongol subordinates for military merits while at the same time strategically relocating their troops and families away from the capital.
