Moreover, before the Manchu entered the customs, they spared no effort to fight for Mongolia, and finally eliminated the die-hards such as Li Dan Khan. Most of them are attached like Horqin, but the way to make them willing to serve the interests of Manchu is to marry each other, because children of two ethnic origins are happy when they become emperors, and their interests can also be guaranteed. Mongolians are die-hard allies of the late Jin Dynasty and the Qing Dynasty, and the main political and military supporters. In order to consolidate the rule and rule the vast Central Plains and Han people, the rulers of the Qing Dynasty must maintain the Manchu-Mongolian alliance and take the Manchu-Mongolian Eight Banners as the fundamental support.
During the whole Qing Dynasty, the Mongols in Eight Banners were treated the same as Manchu, while the people in Hanqi were much worse and had different trust. Only the Manchu in the Eight Banners can be responsible for the security of important places such as the palace, and even the Han people will not have this opportunity.
Through frequent political marriages between Manchuria and Mongolia, Manchuria successfully controlled Mongolia's very powerful military forces, and finally realized its dream of jointly defeating the Ming Dynasty, entering the Central Plains and dominating the world. After Manchuria's entry into WTO, the powerful Mongolia has been there. After all, one mountain can't accommodate two tigers. The continuous marriage between Manchu and Mongolia is also to remove the threat of Mongolia to Manchu rule and stabilize the Qing Dynasty. In the court of the Qing Dynasty, the position of Mongolian concubines was not inferior to that of Manchu concubines, and the last Mongolian queen was Queen Alut of Tongzhi Emperor Zai Chun.
