The Records of the Three Kingdoms, also known by its Chinese title Sanguozhi , is a Chinese historical text which covers the history of the late Eastern Han dynasty (c. 184–220 AD) and the Three Kingdoms period (220–280 AD). It is widely regarded as the official and authoritative historical text for that period. Written by Chen Shou in the third century, the work combines the smaller histories of the rival states of Cao Wei, Shu Han and Eastern Wu in the Three Kingdoms period into a single text. The Records of the Three Kingdoms provided the basis for the historical novel Romance of the Three Kingdoms written by Luo Guanzhong in the 14th century.
