Wuqiao mutiny

The Wuqiao mutiny (吳橋兵變) was a military revolt from 1631 to 1633 during the late years of the Ming dynasty, led by Kong Youde and Geng Zhongming. Both men were lieutenants under the command of general Mao Wenlong, the defender of Pi Island (Dongjiang), a strategically crucial island in the Yellow Sea that guarded the coastal land corridor into Joseon, a Ming vassal state at the flank of the Manchu-led Later Jin (which later became the Qing dynasty). The revolt was eventually crushed by Ming government forces, although many surviving rebels managed to flee across the Bohai Sea and surrendered to the Manchu, significantly upsetting the balance of power between the Ming and the Later Jin.
