Ligdan Khan
Although, the Mongols of the Gansu–Qinghai Lake areas under the rule of the Yuan dynasty submitted to the Ming dynasty after the Yuan dynasty's fall in 1368, the Upper Mongols came there in 16th and 17th centuries. Many Mongol emperors and rulers of the Northern Yuan dynasty such as Dayan Khan, Ligdan Khan, the Ordos and Tümed princes invaded, or took refuge, in Qinghai from 1509 to 1632. The Tümed Mongols ruled in the Ordos region and they gradually extended their domain into northeastern Qinghai.
