Campaign against Yuan Shu
The
campaign against Yuan Shu was a
punitive expedition that took place between 197 and 199 in the
late Eastern Han dynasty. The campaign was initiated by the Han government against warlord
Yuan Shu after Yuan declared himself emperor of the new Zhong dynasty, an act perceived as treason against
Emperor Xian, the nominal Han ruler. The campaign concluded with the defeat of Yuan Shu and collapse of his self-established Zhong dynasty.
