The territory of the Ming Dynasty initially included parts of Xinjiang. How are these territories lost step by step?

The land of the motherland in the Ming Dynasty was also very large. As we all know, at the peak of China's territory, the Ming Dynasty was the penultimate, and at the most prosperous period of the country, its territory was about 6,543,800 square kilometers. Although there was so much land in front, the land in the Ming Dynasty was seriously reduced, and the actual control area was only over 3 million square kilometers.

The reason is not that the Ming Dynasty had no intention to explore new territories, but that the neighboring countries plundered too much in the later period and the Ming Dynasty emperors were mediocre. It was not until the decline of the country that the Ming Dynasty brought those tribes or regimes such as the frontier into its own copyright and control scope. The former emperor opened up many territories, but the later emperor could not protect them, so the land gradually decreased.

As we all know, the land of the Ming Dynasty was about three or four million square kilometers, and the territory of the Qing Dynasty was about130,000 square kilometers. This statement is a bit out of context, but it is actually a comparison between the peak period and the recession period. When Ming Chengzu was here. Northeast China, Tibet and Dongjiang all belong to the Ming Dynasty.

In the Ming dynasty, many militarized places were established in Tibet, and they also had the right to collect taxes in Tibet. After that, some emperors paid little attention to the maintenance of these lands. After giving up part of the land outside the Great Wall, he ruled the eastern part of Xinjiang intermittently, and then gave up completely in the back. The farthest place to the west in the Ming Dynasty was Jiayuguan, and the former Xinjiang region was no longer in hand. ?
