The Choghtu Khong Tayiji's Khalkhas (1 banner): Poet, supporter of Ligdan Khan, and opponent of the Dalai Lama's "Yellow Hat" order, Tsogtu Khong Taiji moved to Qinghai with his subjects sometime after 1624. Ligdan Khan and Tsogtu Khong Taiji were supposed to meet in Qinghai and eventually build a Mongol base that is independent of the Manchu rule which was geographically far from the Manchu emperor's reach. Moreover, it was clear to the two Mongol Khans that Tibetan Dalai Lama's influence in Mongol affairs was increasing. So the two decided to end the influence of Dalai Lama and the "Yellow Hat" order by supporting the "Red Hat" order. However, majority of Ligdan Khan's subjects and soldiers died because of smallpox on the way to Qinghai. After Ligdan's death, Tsogtu Taiji began attacking dGe-lugs-pa monasteries. When Tsogtu sent 10,000 men under his son Arslang against the Dalai Lama in Lhasa, Arslang switched sides and supported the Dalai Lama. The dGe-lugs-pa hierarch, the Fifth Dalai Lama (1617–82), summoned the Oirat Güshi Khan Toro-Baiku, whose 10,000 men in early 1637 crushed Tsogtu’s 30,000 at Ulaan-Khoshuu; Tsogtu Taiji was killed. Today the Oirats of Gushi Khan is also known as the "Upper Mongols" or the "ДЭЭД МОНГОЛ", and they still reside in Qinghai forming 21 banners. The remnants of Tsogtu Khong Taiji's Halhs form only one banner and are known as the "Lower Mongols" or "ДООД МОНГОЛ". Tsogtu Khong Taiji is known as Tsogtu Khan among the Khalkha Mongols in Qinghai.
