Emperor Gaozu of Han
The Han dynasty (206 BCE – 220 CE) was a period of Ancient China divided into the Western Han (206 BCE – 9 CE) and Eastern Han (25–220 CE) periods, when the capital cities were located at Chang'an and Luoyang, respectively. It was founded by Emperor Gaozu of Han and briefly interrupted by the regime of Wang Mang (r. 9–23 CE) who usurped the throne from a child Han emperor.
