The Three Kingdoms (220–280 AD) was the tripartite division of China between the states of Wei, Shu, and Wu. It started with the end of the Han dynasty and was followed by the Jin dynasty. The term "Three Kingdoms" is something of a misnomer, since each state was eventually headed not by a king, but by an emperor who claimed suzerainty over all China. Nevertheless, the term "Three Kingdoms" has become standard among English-speaking sinologists. To distinguish the three states from other historical Chinese states of the same names, historians have added a relevant character to the state's original name: the state that called itself Wei (魏) is also known as Cao Wei (曹魏), the state that called itself Han (漢) is also known as Shu Han (蜀漢) or just Shu (蜀), and the state that called itself Wu (吳) is also known as Eastern Wu (東吳; Dōng Wú) or Sun Wu (孫吳).
