Heavenly King or Tian Wang (Chinese: 天王; pinyin: Tiān Wáng; Wade–Giles: Tien1-wang2) is a Chinese title for various religious deities and divine leaders throughout history, as well as an alternate form of the term Son of Heaven, referring to the emperor. The Chinese term for Heavenly King consists of two Chinese characters meaning "heaven/sky" and "king". The term was most notably used in its most recent sense as the title of the kings of the Taiping Heavenly Kingdom, but is also used in religious (particularly Buddhist) contexts as well.
