Religion in Mongolia

Tengri (; Old Uyghur: 13px ; Middle Turkic: ; ; ; ; ; ; ; Proto-Turkic: / ; Mongolian script: , ; , ; , ) is the all-encompassing God of Heaven in the traditional Turkic, Yeniseian, Mongolic, and various other nomadic religious beliefs. Some qualities associated with Tengri as the judge and source of life, and being eternal and supreme, led European and Muslim writers to identify Tengri as a deity of Turkic and Mongolic peoples. According to Mongolian belief, Tengri's will (jayayan) may break its own usual laws and intervene by sending a chosen person to earth.
