Tengriism (or Tengerism, Tengrianism  ) is a Central Asian religion that incorporates elements of shamanism, animism, totemism and ancestor worship. In old times, it was the major belief of Turkic peoples (such as the Huns, Bulgars, Xiongnu), Hungarians and Mongols  . It focuses around the sky deity Tengri (or Tangri, Tanr etc.) and reverence for the sky in general. Majority of Tengrists today live in Northern and Central Asia such as Khakassia and Tuva. "Khukh" and "Tengri" literally mean "blue" and "sky" in Mongolian and modern Mongolians still pray to "Munkh Khukh Tengri" ("Eternal Blue Sky"). Therefore Mongolia is sometimes poetically referred to by Mongolians as the "Land of Eternal Blue Sky" ("Munkh Khukh Tengriin Oron" in Mongolian).
