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.
Emperor Ping of Han
Emperor Ping (9 BC – 3 February 6 CE) was an emperor of the Chinese Han Dynasty from 1 BC to AD 5. After Emperor Ai died childless, the throne was passed to his cousin Emperor Ping—then a child of eight years old. Wang Mang was appointed regent by the Grand Empress Dowager Wang. Dissatisfied with his father's dictatorial regency, in AD 3, Wang's son Wang Yu (王宇) conspired with Emperor Ping's maternal uncles of the Wei clan against Wang, but after they were discovered, Wang had not only Wang Yu and the Weis (except Consort Wei) put to death, but also used this opportunity to accuse many actual or potential political enemies as being part of the conspiracy and to execute or exile them. From here onwards, the Han Dynasty existed only in name. Furthermore, Wang Mang also designated his daughter as the empress consort to Emperor Ping to codify his legitimacy to power. Emperor Ping was allegedly poisoned by Wang Mang after reigning less than six years, because Wang was concerned that he would avenge his uncles, and his successor, the infant Emperor Ruzi, would be chosen by none other than Wang Mang himself.
