The
Book of Han and
Records of the Three Kingdoms join the original Han-era universal history
Records of the Grand Historian to constitute the first three entries in the
Twenty-Four Histories canon, with each work cementing the new genre's literary and historiographical qualities as established by
Sima Qian. The
Records of the Three Kingdoms consist of 65
fascicles divided into three books—one per eponymous kingdom—totaling around 360,000
Chinese characters in length. The
Book of Wei,
Book of Shu, and
Book of Wu receive 30 fascicles, 15 fascicles, and 20 fascicles respectively. Each fascicle is organised in the form of one or more biographies. The author
Chen Shou was born in present-day
Nanchong,
Sichuan, then in the state of
Shu Han. After the
Conquest of Shu by Wei in 263, he became an official historian under the government of the
Jin dynasty, and created a history of the
Three Kingdoms period. After the
Conquest of Wu by Jin in 280, his work received the acclaim of senior minister
Zhang Hua. Prior to the Jin dynasty, both the states of
Cao Wei and Wu had already composed their own official histories: the
Book of Wei by
Wang Chen,
Xun Yi, and
Ruan Ji; and the
Book of Wu by
Wei Zhao,
Hua He,
Xue Ying, Zhou Zhao (), and Liang Guang (). Additionally,
Yu Huan had completed his privately compiled history of Wei, the
Weilüe. Chen Shou used these texts as the foundation of the
Records of the Three Kingdoms. However, since the state of Shu lacked an official history bureau, the
Book of Shu in the
Records was composed by Chen Shou himself based on his earlier personal notes about events in Shu and other primary sources he collected, such as his previously compiled writings of
Zhuge Liang. The
Records of the Three Kingdoms used the year 220 CE—when the last emperor of the Han dynasty was forced to abdicate to Cao Pi—as the year in which the Wei dynasty was established. The
Records refer to the rulers of Wei as 'Emperors' and those of Shu and Wu as 'Lords' or by their personal names. ==Dates==
