Burkhanism or Ak Jang (Ак јаҥ "the White Faith") is an indigenist new religious movement that flourished among the Altai people of Russia's Altai Republic between 1904 and the 1930s. The Russian Empire was suspicious of the movement's potential to stir up native unrest and perhaps involve outside powers. The Soviet Union 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. On the whole, the Burkhanist movement was shown to be a syncretistic phenomenon combining elements of ancient pre-shamanist, shamanist, Tibetan Buddhist and Eastern Orthodox Christian beliefs. According to a professor of Tomsk State University Liudmila Sherstova, it emerged in response to the needs of a new people—the Altai-kizhi or Altaians who sought to distinguish themselves from the neighboring and related tribes and for whom Burkhanism became a religious form of their ethnic identity. Burkhanism is the usual English-language scholarly name, which has its origin in the Russian academic usage. One of the Burkhanist deities is Ak-Burkhan, or "White Burkhan". Burkhan is Turkified version of the name Buddha, 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. The Altaian name for the religion is Ak Jang "the White Faith". "White" refers to its emphasis on the upper world in the three-world cosmology of Tengrism.
