The primary religion practiced in the Mongol Empire was Tengrism, a spiritual tradition that emphasizes worship of the sky god Tengri and connection to nature. However, due to its vastness and the diverse cultures within the empire, other religions coexisted, including Buddhism, Islam, and Shamanism. The Mongols were generally tolerant of different beliefs and often incorporated elements from the various religions present in the territories they conquered. This religious pluralism allowed for a relatively peaceful coexistence among different faiths, facilitating trade and cultural exchange across the empire.
