Emperor Gaozu of Han [SEP] Introduction
Emperor Gaozu of Han (256 – 1 June 195 BCE), born Liu Bang () with courtesy name Ji (季), was the founder and first emperor of the Han dynasty, reigning from 202 – 195 BCE. His temple name was "Taizu" while his posthumous name was Emperor Gao, or Gaodi; "Gaozu of Han", derived from the "Records of the Grand Historian", is the common way of referring to this sovereign even though he was not accorded the temple name "Gaozu", which literally means "High Founder". Liu Bang was one of the few dynasty founders in Chinese history who was born into a peasant family.
