Under Communist rule, shamanism was banned in Mongolia for 70 year. In 1992 the ancient traditions became protected by the country’s constitution.
The distance between Mongolia and European countries famous for its summer solstice celebrations is huge, but the traditions in Asia are not so different. Celebration of the summer solstice in Mongolia involves a number of fire rituals.
There are naturally many other countries where summer solstice is celebrated every year. Each culture has its own unique ancient tradition.
