Khan of Heaven

Khan of Heaven or Tian Kehan, Celestial Khagan, Tengri Khan (Chinese: 天可汗; pinyin: Tiān Kèhán; Wade–Giles: T'ien K'ehan) was a title addressed to the Emperor Taizong of Tang by various Turkic nomads. It was first mentioned in accounts on May 20, 630 and again on October 24, 646, shortly after the Eastern Turkic Khaganate and Xueyantuo were annihilated by the Tang dynasty. A later letter sent by the Tang court to the Yenisei Kirghiz Qaghan explained that "the peoples of the northwest" had requested Emperor Taizong of Tang to become the "Heavenly Qaghan".
