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.
Marquess Jing of Han
Marquess Jing of Han (Chinese: 韩景侯; pinyin: Hán Jǐnghóu) (died 400 BC), ancestral name Jì (姬), clan name Hán (韩), personal name Qían (虔), was the ruler of the State of Han between 408 BC until his death in 400 BC. Marquess Jing was the son of Wuzi of Han. It was during his rule that the State of Han became a recognized state. In the first year of his reign, he attacked the State of Zheng and took over Yongqiu in today's Qi County, Henan. The next year, his army lost to Zheng at Fushu in today's Dengfeng, Henan. In 403 BC, Marquess Jing, along with Marquess Wen of Wei and Marquess Lie of Zhao partitioned the powerful Jin state into the Han, Wei, and Zhao states marking the beginning of the Warring States Period and Han as an independent polity. King Weilie of Zhou was forced to elevate Jing's title from viscount to marquess. Marquess Jing then moved the capital of Han from Pingyang to Yangzhai. In 400 BC, the capital Yangzhai was subject to a siege by the Zheng army. Marquess Jing died later that year and was succeeded by his son Marquess Lie of Han.
