We all know that in the late Qing Dynasty, the Qing Dynasty was weak and was invaded by the Eight-Nation Alliance and snatched away countless gold and silver treasures, and even many small countries on the neighboring sides began to talk about the Great Qing. So at that time, Mongolia was bordered by the Qing Dynasty, so why didn't it take the opportunity to go to war with the Qing Dynasty?
The war between the Qing Dynasty and the Mongols is not covered in our history textbooks, so most people do not understand it. In fact, Mongolia and the Qing Dynasty have always had wars and even fought for more than 100 years. Until the end, Russia and the Qing Dynasty jointly launched a back-and-forth attack on Mongolia, and Mongolia was defeated and defeated, so Mongolia was divided between the Qing Dynasty and Russia, and part of the land was divided between the Qing Dynasty and Russia, and part of the land was divided into Russia and became the territory of present-day Russia, and part of the land annexed by the Qing Dynasty became the current Inner Mongolia and Outer Mongolia.
However, the origin of the war between the Qing Dynasty and the Mongols was at the end of the Ming Dynasty, when the Ming Dynasty was in chaos, the Qing soldiers took advantage of the void to enter the Central Plains, and the north of the Ming Dynasty was also inhabited by many Mongolian nomadic tribes that had split off from the Yuan Dynasty, such as the Yarkand, Mughals, Turpan, etc. are all part of the Mongol Khanate.
After the Ming Dynasty defeated the Yuan Dynasty that year, it adopted the method of the Yuan Dynasty to attack the Southern Song Dynasty, and in turn attacked the Mongols while spending a lot of money to bribe high-level Officials of Mongolia, resulting in many Mongol generals and tribes defecting to the Ming Dynasty. Then the remaining tribes that did not submit to the Ming Dynasty, the Mongol tribes all stood on their own and developed separately. By the beginning of the Qing Dynasty, the Mongolian steppe gradually developed into three major khanate alliances, namely the Khalkha Alliance, the Moxi Mongol Alliance, and the Southern Mongolian Alliance, which were divided into more than a dozen nomadic tribes, implicating small tribes, etc. Each alliance and tribe did not violate the river water, and each of them took care of each other. So after the Qing Dynasty was stable, he began to pay attention to the Mongolian lands.
Since the Mongol Alliance in southern Mo was closest to the Border of the Qing Dynasty in terms of location, the Qing soldiers were the first to wage war against the Mongol soldiers in southern Mo. Coincidentally, in the Mo'nan Alliance, there was a Khan named Lin Dan Khan, who was a descendant of Genghis Khan, but the other Khan kings did not give him face, and the Khalkha Khan king did not even recognize him as the Khan King, resulting in many Mongol tribes disobeying Lin Dan Khan, and his territory was only one tribe of Chahar.
Later, Lin Dan Khan may have felt insulted, so he launched a war to follow his ancestor Genghis Khan to unify Mongolia. However, the other Mongol tribes did not bird him at all, let him jump around there, and also caused Horqin to defect to Nurhaci, and eventually formed an alliance with the Manchus of the Qing Dynasty, and soon after Horqin returned to Mongolia with Qing soldiers to destroy Lin Dan Khan, so that the southern Mongolia actually had an "ambiguous" relationship with the Qing Dynasty.
Soon after the southern Mongolian region was settled for the Qing Dynasty, it was soon the turn of the Western Mongol Alliance, where the Mongols were mainly Mongols left over from the previous Chagatai Khanate, which had basically been assimilated by the Turks. Others are the Washi tribe, which moved west into five tribal groups, the more well-known of which are the Dzungars and the Turks. When the Qing Dynasty first invaded the southern Mongolian region, the Western Mongolian tribes were also attacked by the Khalkha Mongol tribes and the Russian army, so the Western Mongols asked the Qing Dynasty for support and eventually broke the crisis, so the Western Mongolian tribes finally surrendered to the Qing Dynasty. Based on this subordination, the Qing Dynasty and Mongolia never had a war in the following days.
In fact, after the Manchus of the Qing Dynasty entered the customs, they attached great importance to their relations with Mongolia and wanted to block Russia through Mongolia. During the reign of Kangxi, the Dzungar Khanate sent troops to destroy many tribes in northern Mongolia, and the desperate northern Mongols did not want to submit to Russia in the north, and felt that the Manchus of the Qing Dynasty were more cordial in blood, so they surrendered to the Qing Dynasty to obtain the protection of the Qing Dynasty. In the thirtieth year of the Kangxi Dynasty, Kangxi and the leaders of the tribes in northern Mobei reached a consensus in the Duolunor Alliance and announced to the world that they would henceforth be ruled by the Qing Dynasty. Therefore, most of the tribes in Mongolia need the protection of the Qing Dynasty, and the rest of the strength is insufficient, so they never dare to fight with the Qing Dynasty.
