三藩之乱
The Revolt of the Three Feudatories was led by three territories (, "Sānfàn") in southern China bestowed by the early Manchu rulers on three Han Chinese generals — Wu Sangui, Geng Jingzhong, and Shang Zhixin. In the second half of the 17th century, they revolted against the Qing government. This rebellion came as the Qing rulers were establishing themselves after their conquest of China in 1644 and was the last serious threat to their "imperium" until the 19th-century conflicts that ultimately brought about the end of the dynasty in 1912. The revolt was followed by almost a decade of civil war which extended across the breadth of China.
