Burkhanism
Burkhanism or Ak Jang (Altay: Ак јаҥ) is a new religious movement that flourished among the indigenous people of Russia's Gorno Altai region (okrug) between 1904 and the 1930s. Czarist Russia was suspicious of the movement's potential to stir up native unrest and perhaps involve outside powers. The Soviet authorities ultimately suppressed it for fear of its potential to unify Siberian Turkic peoples under a common nationalism.
Originally millenarian, charismatic and anti-shamanic, the Burkhanist movement gradually lost most of these qualities—becoming increasingly routine, institutionalized (around a hierarchy of oral epic singers), and accommodating itself to the pre-existing Altaian folk religion. It exists today in several revival forms.
Origins of the name
Burkhanism is the usual English-language scholarly name. One of the Burkhanist deities is Ak-Burkhan, or "White Burkhan." Burkhan means "god" or "buddha" in Mongolic languages, yet Burkhanism is not considered Buddhist, as the term is also used in shamanistic nomenclature. For example, in Mongolian Shamanism, the name of the most sacred mountain, the rumored birthplace and final resting spot of Genghis Khan, is also Burkhan Khaldun. Ak-Burkhan is only one of a pantheon of deities worshiped by Burkhanists (see list below), but Ak-Burkhan nevertheless provides the name of the religion in Russian, and thence into other languages.
