Why were the Mongols in the late Ming Dynasty so

Mongolia really caused losses to the Ming Dynasty in the early stage. By the end of the Ming Dynasty, the Ming Dynasty had been able to appease Mongolia very well. Mongolia rarely held back its borders in the late Ming Dynasty. However, the key to the Ming Dynasty's dealing with Mongolia was not force, but several major factors:

A. Mongolia's degradation. Including the degradation of the Mongols' own combat effectiveness, the split of the Mongolian tribes into several tribes (Tatar, Oara, Mobei, Moxi, Monan, Turgut, Horqin, etc.), the decline of the Golden Family (which has a lot to do with the Northern War in the early Ming Dynasty) major relationship), coupled with a long-term ban on the export of ironware.

B. The Han people entered Mongolia. The Han people brought advanced productive forces, and since they were located in the Hetao area, the land was fertile, so the income from farming, grazing, and trading was enough to keep them from starving to death. (The Han people settled in Mongolia, which lasted from the Ming Dynasty until the end of the Qing Dynasty, when the struggle between Mongolia and Han ended) (Bansheng refers to the place where the Mongolian and Han people live in Fengzhoutan (now Hohhot, Inner Mongolia Autonomous Region).)

C , Lamaism into Mongolia, this is the most fatal. How powerful Tibet was during the Tang Dynasty, but by the Song, Yuan, Ming and Qing dynasties, the Tibetan people's fighting power had become the fifth scum of the war, which was due to the influence of Lamaism. The Qing Dynasty could not hold the border without Mongolia, and it also gained the legacy of the Ming Dynasty.
