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.
Liu Yao (warlord)
Liu Yao (157–198), courtesy name Zhengli, was a provincial governor and warlord who lived during the late Eastern Han dynasty of China. He was a descendant of Liu Fei, the eldest son of the Han dynasty's founding emperor, Liu Bang (Emperor Gao). When he was 18, he became famous after rescuing a relative who was being held hostage by bandits. He started his career in the Han civil service after being nominated as a "xiaolian", and was known for his incorruptibility. In 194, although he was appointed by the Han imperial court as the governor of Yang Province, he barely managed to gain a foothold over his jurisdiction because the warlord Yuan Shu controlled a large part of the territories around the Huai River region in Yang Province. In 195, conflict broke out between Liu Yao and Yuan Shu, who sent his ally Sun Ce to attack Liu Yao. Sun Ce defeated Liu Yao and forced him to retreat south into present-day Jiangxi, where Liu Yao defeated a minor warlord Ze Rong and died of illness shortly later.
