The Yellow Emperor, also known as the Yellow Thearch, or by his Chinese name Huangdi, is a deity (shen) in Chinese religion, one of the legendary Chinese sovereigns and culture heroes included among the mytho-historical Three Sovereigns and Five Emperors and cosmological Five Forms of the Highest Deity. Calculated by Jesuit missionaries on the basis of Chinese chronicles and later accepted by the twentieth-century promoters of a universal calendar starting with the Yellow Emperor, Huangdi's traditional reign dates are 2697–2597 or 2698–2598 BCE.
