Shi Kefa
In 1644, Beijing fell to rebels led by Li Zicheng and the Chongzhen Emperor hanged himself on a tree at modern-day Jingshan Park in Beijing. Manchu armies aided by Wu Sangui's forces defeated the rebels and took the city. The Ming remnant forces retreated to Nanjing where they put Prince Fu on the throne as the Hongguang Emperor in an attempt to continue the Ming dynasty in the south. The next year, the Manchu armies led by Dodo advanced south and conquered Yangzhou and Nanjing while the Ming leader defending Yangzhou, Shi Kefa, was killed. The Hongguang emperor was captured and executed.
