The Three Kingdoms of Cao Wei, Shu Han, and Eastern Wu dominated China from 220 to 280 AD following the end of the Han dynasty. This period was preceded by the Eastern Han dynasty and was followed by the Western Jin dynasty. Academically, the periodisation begins with the establishment of Cao Wei in 220 AD and ends with the conquest of Wu by Jin in 280 AD. The period immediately preceding the Three Kingdoms, from 184 to 220 AD, was marked by chaotic infighting among warlords across China as Han authority collapsed. The period from 220 to 263 AD was marked by a comparatively stable arrangement between Cao Wei, Shu Han, and Eastern Wu. This stability broke down with the conquest of Shu by Wei in 263 AD, followed by the usurpation of Cao Wei by Jin in 266 AD and ultimately the conquest of Wu by Jin in 280 AD.
