Emperor Yuan of Han, personal name Liu Shi, was an emperor of the Chinese Han dynasty. He reigned from 48 BC to 33 BC. Emperor Yuan promoted Confucianism as the official creed of the Chinese government. He appointed adherents of Confucius to important government posts.

Throughout Chinese history, "Emperor" was the superlative title held by the monarchs who ruled various imperial dynasties. In traditional Chinese political theory, the emperor was the "Son of Heaven", an autocrat with the divine mandate right to rule all under Heaven. Emperors were worshiped posthumously under an imperial cult. The lineage of emperors descended from a paternal family line constituted a dynasty, and succession in most cases theoretically followed agnatic primogeniture.
