[1] Buddhism first entered Mongolia during the Yuan dynasty (thirteenth-fourteenth century) and was briefly established as a state religion.
The cult of Genghis Khan, who had been accepted into the tngri, the highest pantheon of spirits in Mongolian shamanism, became annexed into Buddhist practice as well.
Mongolia itself was at a political and developmental standstill until the sixteenth century, when after the conversion of Altan Khan Buddhism re-established itself.
[3] In 1691, after Outer Mongolia had been annexed by the Qing dynasty, Buddhism became the dominant religion of the entire area and shamanism began incorporating Buddhist elements.
Violent resistance in the eighteenth century by the hunting tribes of Northern Mongolia against the (Buddhist) ruling group, the Khalk Mongols, led to the foundation of black shamanism.
