Ming Chinese general Cao Qin staged a failed coup against the Tianshun Emperor.

The Ming dynasty, officially the Great Ming, was an imperial dynasty of China that ruled from 1368 to 1644, following the collapse of the Mongol-led Yuan dynasty. The Ming was the last imperial dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng, numerous rump regimes ruled by remnants of the Ming imperial family, collectively called the Southern Ming, survived until 1662.

The Rebellion of Cao Qin was a day-long uprising in the Ming dynasty capital of Beijing on August 7, 1461, staged by Chinese general Cao Qin and his Ming troops of Mongol and Han descent against the Tianshun Emperor. 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.

Emperor Yingzong of Ming, personal name Zhu Qizhen, was the sixth and eighth emperor of the Ming dynasty. He ruled as the Zhengtong Emperor from 1435 to 1449, and as the Tianshun Emperor from 1457 until his death in 1464.
