We read all the lead to present a different history.
Kublai Khan (1212–1294) was a Mongol politician, military strategist, fourth son of The Overseer Torre, and founding emperor of the Yuan Dynasty. After the death of his elder brother Möngke in 1260, Kublai Khan took the throne as Khan in Kaiping. In 1271, the name of the "Great Mongol" was changed to "Yuan", and in 1272, the capital was designated as Dadu (present-day Beijing), creating the 98-year-old Yuan Dynasty. So what contributions did Kublai Khan make to Chinese history?

1. Change the name of Mongolia to "Yuan" and make the capital city the capital of Dadu
Second, destroy the Southern Song Dynasty and unify the whole country
After the fall of the Southern Song Dynasty in 1279, the unification of the Yuan Dynasty ended the division and war situation of the confrontation between the north and the south of China since the Tang Dynasty, and played a great role in the consolidation and discovery of the multi-ethnic unified state.
The centralization of power has been strengthened, and state institutions and a strict legal system have been established
Kublai Khan stripped the clans of their administrative, military, and judicial powers, and in turn stripped the kings of their economic and political power in terms of taxation and official appointments, thus concentrating the power of the central government.
Fourth, pay attention to agriculture, build new water conservancy, and develop the economy
A series of measures have been taken to restore and develop agricultural production, and institutions have been set up at all levels to be devoted to agriculture. The central government has set up a special superintendent of water, and a river and canal department has been set up everywhere to dredge the river channel, repair the embankment and build water conservancy. Restrict pasture encroachment on farmland and prohibit livestock from damaging farmland and crops. Implement tun tian uniforms and reclaim wasteland.
5. Expedition overseas
After the fall of the Song Dynasty, Kublai Khan launched a series of wars against neighboring countries, such as Annam, Champa and Japan, although various reasons such as weather or geography were almost fruitless, but these laid the foundation for the expansion of the territory of the Yuan Dynasty later.
6. Formulate Mongolian characters
In order to improve the cultural level of the Mongols, Kublai Khan ordered the Tufan monk Basipa to formulate a new Mongolian character, promulgate the world, and translate some Chinese classics.
Seventh, attach importance to the development of culture and science and technology
Emphasis was placed on astronomy and the number of days a year was set at 365.2425 days.
Set up a si nong, gather various experiences, and compile it into the "Nong Sang Yang Essentials". Unified currency, printing "treasure money". To develop culture and art, Yuanqu is the best embodiment. The scientific and technological level of Kublai Khan in the Yuan Dynasty was at the forefront of the world at that time, of which astronomical, geographical, agricultural, medical and other scientific and technological achievements were the most prominent.
