Abstract:  Mongolian descent, national unity, the establishment of nation- state and the formation of national culture cannot be
separated from the participation of religion. Mongolian natural worship, soul concept, ancestral worship, shamanism, Lamaism and
other religious ideas are accompanied by the formation and development of the Mongolian group. The Mongolian ethnic and religious
interaction is an important part of ethnic religious theory study.

Key words:  ethnic religion theory, Mongolian, ethnic and religious relations
