1. Although there are few Mongolians, they still exceed tens of thousands.
2. Although the Mongolian soldiers are small, it does not mean that the Mongolian army is small. There are many troops from other races in the Mongolian army, such as the Han and the Khitan.
Here I want to talk about the tactics adopted by the Mongols. After the Mongols capture a place, they usually recruit local men to serve as soldiers or to serve and transport supplies. This has two advantages. One is that after a large number of local men are mobilized, it will be easier to rule. Those who remain will be old, weak, women and children, and will not be prone to unrest. On the other hand, they used these people to fight wars, supplement the shortage of Mongolian soldiers, and promote some people to achieve the purpose of winning over.
Two very famous nations perished under such strategies. One is the Khitan tribe that once dominated the north and established the Liao Kingdom. The Khitan Yelu Chucai even served as the Prime Minister of Mongolia. However, because the Khitans were good at fighting, the Mongols recruited a large number of men from the Khitan tribe and added them to other armies. And the army was scattered everywhere. In this way, there were basically no gathering places for the Khitan people, and the nation died out after the Yuan Dynasty.
The other Xixia Dangxiang tribe, which has been in the northwest for hundreds of years, said that it was because Genghis Khan failed to attack Dangxiang and wanted to massacre the entire Dangxiang tribe. However, in fact, the problem of the entire Dangxiang tribe was similar to that of Khitan, and only a small number of people were massacred. , mostly because of Mongolian policies, which led to the final demise of the nation.
