It is not appropriate to say how much the Ming Dynasty lost, because the Mongolian grassland in the territory of the Yuan Dynasty and the territory from northern Siberia to the Arctic Ocean were all dowry brought by the Yuan Dynasty after it entered the Central Plains. If expressed by a formula, it is the territory of the Yuan Dynasty = the territory of the Central Plains+the grassland regime+Siberia further away (there was West Asia at that time, and later Xu Liewu established the Ili khanate). Compared with the traditional Central Plains Dynasty, the only defect of the Yuan Dynasty was the territory of the Chagatai khanate in the western regions. Because the western regions belonged to the fiefs of kings in Genghis Khan's era, he gave the fiefs of the Chahetai series to his son. If the territory lost by the Ming Dynasty relative to other unified dynasties is the Western Region. Of course, what was lost in the eastern corner gained, and the integration of slaves from the northeast into the territory also made up for the deficiency of the western regions.

Obviously, the Ming Dynasty established by Zhu Yuanzhang could not completely inherit the territory of the Yuan Dynasty.

If you follow Zhu Yuanzhang's slogan of building the army? Expel the Tatars and restore China? Generally speaking, the Ming Dynasty basically achieved its goal. For the Ming dynasty, the will of the emperor was basically the will of the country. Therefore, the purpose of Zhu Yuanzhang's starting an army can be interpreted as expelling the Yuan Dynasty from the grassland hometown and restoring the Han family's rule in the Central Plains. Let's take a look at the most representative territory of the Han and Tang Dynasties, the traditional territory of the Central Plains Dynasty:

The territorial composition of the Tang Dynasty is as follows: Western Regions+Grassland+Central Plains+Koguryo+Jiaotoe. Of course, before the establishment of political power for Uighur, the grassland occupied a short time. After Koguryo was destroyed, it did not occupy it for a long time. According to the map of the Ming Dynasty, we can see that apart from the Western Regions, the Ming Dynasty also added the regions of Uszang and Nurgandus. Obviously, after the expansion of the Nuer apprentice in the northeast during the Ming Dynasty, the10 million square kilometers in its heyday was second only to the Han and Tang Dynasties.

Goguryeo in the Tang Dynasty was incorporated into the territory of the Central Plains from four counties in the Han Dynasty, and it can still be used as the territory of the Central Plains Dynasty in the Wei and Jin Dynasties. However, since the rise of Koguryo, it has been separated from the territory of the Central Plains, and it was not until Tang Gaozong destroyed Koguryo that it was regained. But it, like Tiao, has been separated from the territory of the Central Plains since the demise of the Tang Dynasty, so it is not completely within the scope of the traditional territory. In this regard, the Ming Dynasty completed its historical mission in the territory during Judy's period.

The national strength of the Ming Dynasty was far less than that of the Han and Tang Dynasties, so the grassland could not be settled in the late Ming Dynasty. Look at the Huns and Turks in the Han and Tang Dynasties. After being defeated by the Han and Tang Dynasties, it was forced to move westward. Obviously, the Ming dynasty could not do this, but only temporarily lifted the military threat of grassland to the Ming dynasty. Moreover, this strategy of not completely eradicating the threat has great opportunism, that is, the role of hot weapons in the skilled use of the Ming army. During the Han and Tang Dynasties, there were a lot of elite cavalry who could capture the flag, so the Ming army represented by infantry and Jishen camp could only defeat the Mongolian army. In the face of the tactics of the Mongolian and Yuan armies coming and going like the wind, if Daming is still imagining Siberia and the Arctic Ocean, it is really a bit too much.

The mobility, tribe and determination of the army were not firm enough, and the grassland policy of the Ming Dynasty was not coherent, which led to the grassland of the Ming Dynasty not being included in the territory.

The Ming Dynasty experienced three stages to Mobei Mongolia: the first stage: the name of the Northern Yuan Dynasty existed, and the dominant position of the gold family remained firm. The second stage: the Ming Dynasty gave titles to grassland kings, and Mongolian ministries called them vassals of the Ming Dynasty. The third stage: after the change of the civil fort, the offensive and defensive situation of Ming and Mongolia reversed. Of these three stages, the second stage is most likely to pacify the grassland, but the floating tribes of the Ming army seriously restricted the realization of the strategic goal.

The first stage: the Northern Yuan maintained a relatively sound military and political system, and the title returned to the grassland. At this time, Kublai Khan's golden family still maintained an absolute dominant position on the grassland. At this time, Tatar and Vala had not yet split, and the emperors of the Northern Yuan Dynasty still lived a life of imperial elegance in the northern border. Until the battle of sea fishing, aquamarine captured thousands of people, including the prince of the Northern Yuan Dynasty and the imperial clan of the princess, as well as the seal of the imperial seal. , Tianyuan Titus Timur and the prince fled alone.

The second stage: after Emperor Tianyuan and the Prince fled, their prestige fell to the bottom, and soon the era when the Northern Yuan Dynasty claimed that Khan belonged to the Yuan Dynasty passed. After the rise of Tatar and Vara, Emperor Judy successfully suppressed the grassland several times and maintained the relationship between vassal and vassal by conferring the Tatar Vara patriarch.

The third stage: from the short-sightedness of the Ming dynasty monarch and minister in the Xuanzong period of the Tang Dynasty, the Walla department was able to reunite the grassland. In this way, the grassland regained the initiative after being defeated by the Ming army in the civil war, and Daming was unable to bring the grassland into the territory.
