Emperor Xuan of Han was the tenth emperor of the Chinese Han dynasty, reigning from 74 to 48 BC. During his reign, the Han dynasty prospered economically and militarily became the regional superpower, and was considered by many to be the peak period of the entire Han history. He was succeeded by his son Emperor Yuan after his death in 48 BC.

Emperor Xuan has been considered a hardworking and brilliant ruler by historians. Because he grew up among commoners, he thoroughly understood the suffering of the grassroot population, and lowered taxes, liberalized the government and employed capable ministers to the government. He was said by Liu Xiang to have been fond of reading the works of Shen Buhai, using Xing-Ming to control his subordinates and devoting much time to legal cases. Emperor Xuan was open to suggestions, was a good judge of character, and consolidated his power by eliminating corrupt officials, including the Huo family who had exerted considerable power since the death of Emperor Wu, after Huo Guang's death.
