Everyone thinks that the dynasty with the largest territory in China was the Qing Dynasty, not the Yuan Dynasty, right?

The landlord's point of view is right.

In fact, the relationship between several Mongolian khanates is more like the Commonwealth today than the United States. There is also a central federal government above the United States, which has great power; Member countries of the Commonwealth (Canada, Australia, New Zealand, etc.). ) Only the Queen of England is recognized as the head of state and enjoys complete sovereignty in fact.

And the Tang Dynasty. Although the Tang Dynasty won all previous foreign wars from Taizong to Wuhou, its forces entered Mongolia and the Western Regions, but in these two places, the Tang Dynasty only stationed a small number of troops, set up temporary military institutions, and did not exercise direct administrative power. The local government and most local people live and manage there. Therefore, it is not appropriate to include Mongolia and the western regions in the territory of the Tang Dynasty, just as we cannot include Iraq and Afghanistan in the territory of the United States today.

By the Qing Dynasty, Mongolia and Xinjiang not only retained their military strength, but also established an actual administrative system to govern, especially Xinjiang, which enriched the actual ruling rights of the central government. Because of this, the Qing dynasty was able to rule these areas more firmly than previous dynasties, and most of them were incorporated into today's Chinese territory.
