List of emperors of the Han dynasty
The Han dynasty was founded by the peasant rebel leader (Liu Bang), known posthumously as Emperor Gao ("r". 202 –195 BC) or Gaodi. The longest reigning emperor of the dynasty was Emperor Wu ("r". 141–87 BC), or Wudi, who reigned for 54 years. The dynasty was briefly interrupted by the Xin dynasty of the former regent Wang Mang, but he was overthrown in 23 AD and the Han dynasty was reestablished by Liu Xiu, known posthumously as Emperor Guangwu (r. 25–57 AD), or Guangwu Di. The last Han emperor, Emperor Xian ("r". 189–220 AD), was a puppet monarch of Chancellor Cao Cao (155–220 AD), who dominated the court and was made King of Wei. In 220 AD, Cao's son Pi usurped the throne as Emperor Wen of Wei ("r". 220–226 AD) and ended the Han dynasty.
Annals of the Later Han
Annals of the Later Han or Hou Hanji (後漢紀) is a Chinese history book of the Eastern Han dynasty. It was written by Yuan Hong (328 - 376) during the Jin dynasty (265–420). Yuan spent eight years to complete his Annals. The annals contain 30 books with some 210 thousand Chinese characters. It covers the period from the farmers' revolts of the later years of Wang Mang to the years when Cao Pi, and Liu Bei became emperors; therefore it covers roughly 200 years. The annals were written 50 years earlier than Fan Ye (historian)'s "Book of the Later Han", and it is one of two surviving history books of Eastern Han dynasty.
