モンゴル高原
After the collapse of the Mongol-led China-based Yuan dynasty in 1368, the Yuan court retreated to the Mongolian Plateau, marking the start of the Northern Yuan dynasty (1368–1635). The Mongols returned to their earlier patterns of internal strife and their old shamanist ways after the collapse of Yuan dynasty. It was only in the 16th and 17th centuries did Buddhism reemerge in Mongolia.
