Step-by-step explanation:
Tengrism is a religion that has historically been predominant among the peoples of Central Asia. It combines animism with shamanism and the worship of ancestors. Tengrism centers around the worship of Tengri, a supreme power associated with the sky. Tengrists believe that Tengri is the unknowable One who knows everything and judges people's actions. The religion also acknowledges the existence of other benevolent, evil, or mixed spirits.
Tengrism originated with the Mongol people, and Genghis Khan himself was a Tengrist. The religion was widely practiced by Mongols until the early 14th century when some converted to Islam. However, there has been a revival of Tengrism in Central Asia since the fall of the Soviet Union, with efforts to promote it as an indigenous alternative to foreign religions. Neo-Tengrists are particularly active in Kyrgyzstan, where a scientific center for Tengrist studies has been established in the capital city of Bishkek.
