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.
Henan
Ying Zheng, the leader of Qin, crowned himself (220 BCE) as the First Emperor. He abolished the feudal system and centralized all powers, establishing the Qin dynasty and unifying the core of the Han Chinese homeland for the first time. The empire quickly collapsed after the death (210 BCE) of Ying Zheng and was replaced by the Han dynasty in 206 BC, with its capital at Chang'an. Thus, a golden age of Chinese culture, economy, and military power began. The capital moved east to Luoyang in 25 AD, in response to a coup in Chang'an that created the short-lived Xin dynasty. Luoyang quickly regained control of China, and the Eastern Han dynasty (25–220) began, extending the golden age for another two centuries.
