Mongolia in the ancient times practiced ‘Tengrism’, which had resemblance with the Buddhist principles. They believed in doing good in the physical world to maintain balance and fortify their soul. Their core belief lies in the eternal sky’s worship or ‘Tengri’.
However, with time, the ‘Tengrism’ religion lost its vibrancy and also invasion from many rulers brought about other spiritual beliefs like Manichaeism as the core and sovereign religion. Despite the religion that came with it as well as the modifications in the ruler, Mongolians went through numerous changes in the lifestyle and beliefs. The ‘Tengrism’ faith continued to rise among Mongolians, which led over time to the adoption of the Buddhism and still persisted. This is also because of the fact of the 2 religions becoming similar and around precisely the exact same time, Buddhism was quickly spreading in many parts of Asia.
Even during the rule of Genghis Khan, people had an independence of following their desired religion. Besides Buddhism, Islam also spread its rule over many continents at the exact same time around. The effect of Islam has spread to most areas of Mongolian region. As history reveals, many rulers and invasions later from the century, Altan Khan bestowed on Sonam Gyatsom, a dominant Buddhist figure the name of ‘Dalai Lama’. This started an awakening of Buddhism and a long line of blood legacy throughout the nation.
Even with many historical phenomena, nothing could have averted the religious history mongolia underwent over the century. The Soviet control in the 20th century lacked the history Mongolia had assembled up to now, which suppressed the Mongolian religions, killing clergy members and religious leaders, and ruining ritual sites. On removing the practice of Buddhism this reveals the force.
