At a time when the Mongolian state was nomadic and cities had not yet been erected, the main religion of the Mongols was Tengrianism. From the Great Khan to a simple nomad, everyone worshiped the Great Sky - Tengri and Mother Nature - goddess Umai. In the religion of the ancient Mongols, the cult of totems was of great importance. They believed that everything that surrounds them has a soul. Hunting and raising livestock, nomads were inextricably linked with animals - some of them they revered and deified. Each tribe believed that it originated from a certain type of animal or plant.
