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.
History of the Han dynasty
Eventually, due to his good reputation, Huo Qubing's half-brother Huo Guang was entrusted by Wu to form a triumvirate regency alongside ethnically Xiongnu Jin Midi (d. 86 BCE) and Shangguan Jie (上官桀) (d. 80 BCE) over the court of his successor, the child Liu Fuling, known posthumously as Emperor Zhao of Han (r. 87–74 BCE). Jin Midi died a year later and by 80 BCE Shangguan Jie and Imperial Counselor Sang Hongyang were executed when they were accused of supporting Emperor Zhao's older brother Liu Dan (劉旦) the King of Yan as emperor; this gave Huo unrivaled power. However, he did not abuse his power in the eyes of the Confucian establishment and gained popularity for reducing Emperor Wu's taxes.
