Chroniques des Trois Royaumes
The standard history of the period is the "Records of the Three Kingdoms", compiled by the Western Jin historian Chen Shou in the third century CE. The work synthesizes the histories of the rival states of Cao Wei, Shu Han and Eastern Wu in the Three Kingdoms period into a single compiled text. An expanded version of the "Records of the Three Kingdoms" was published by the Liu Song historian Pei Songzhi in 429, whose "Annotations to Records of the Three Kingdoms" supplemented the original with sizable excerpts of texts unused by Chen Shou and provided commentaries. The resulting work nearly doubled the size of the original "Records", and the composite work of Chen and Pei are canonized as official history (正史).
