How did the Yuan Dynasty achieve national unification?

Personally, I think it should be a unified empire, and the Yuan Dynasty is the largest dynasty in Chinese history. According to the map of the Yuan Dynasty in middle school history textbooks, the territory of the Yuan Dynasty stretched from Sakhalin Island and the Sea of Japan in the east, to the South China Sea in the south, to the Tianshan Mountains in the west, and to the Arctic Ocean in the north, with a total area of more than 20 million square kilometers.

By the time of the Yuan Dynasty, China was already a large territory, including present-day Mongolia, West Asia, and parts of South Asia.

The Yuan Dynasty (1271-1368) was the first unified dynasty in Chinese history to be established by a minority ethnic group.

The Yuan Dynasty was founded by Genghis Khan, and the iron cavalry he led laid down too many places, much more than now.

The territory directly managed by the Yuan Dynasty completely covers the current territory;

During the Yuan Dynasty, China was basically completely unified, and it was also a resettlement.

During the Yuan Dynasty, China had the largest territory and achieved complete unification.

That's too unified, it's just a pity that Japan didn't come in.

The Yuan Dynasty was a truly unifying dynasty.

In 1271, Kublai Khan changed the name of the country to "Da Yuan" in the Book of Changes, and the following year the capital was set in Dadu.

In 1279, after the Battle of Yashan, the exiled regime of the Southern Song Dynasty was completely destroyed, ending the long-term chaos since the end of the Tang Dynasty and achieving complete unification of the whole country.

The Yuan Dynasty was founded in 1271 by Kublai Khan, the fourth son of Temujin, the grandson of Genghis Khan of the Mongol Empire. Prior to this, China was controlled by the Southern Song and Western Xia regimes, and after Temujin began to conquer the northern regions, his sons continued to expand their territory, eventually conquering the Song dynasty in the south, unifying all of China. The unification of the Yuan Dynasty lasted roughly from 1271 to 1368.

1. Hunger. 2. Strategic strength.

3. The corruption of the enemy.

4. Combat effectiveness.

n. Opportunity! (Personally, I think the most important reason).

It's not the only answer, it's a combination of various situations and circumstances.

The unification of the whole country in the Yuan Dynasty was conducive to the exchange and communication of national culture
