No almanac was issued in the Yuan Dynasty.

In fact, the strength of the Yuan Dynasty proved its strength at that time, but its life span was not long compared with other dynasties. The main reasons are unstable internal affairs, split political power and racial discrimination. In the later period, I didn't know how to preserve my strength, which eventually led to defeat and national ruin. In fact, in the final analysis, the demise of the Yuan Dynasty was mainly due to the following reasons.

The first reason is that the internal affairs of the Yuan Dynasty were unstable, the political power in the imperial court was too divided and the management was chaotic. At that time, the Han dynasty was divided into many parts, and at that time, the threat of three parts was even greater. At that time, the imperial court fought for power and profit, which led to the turmoil at that time. In addition, the emperor is indifferent to political affairs and only cares about his own enjoyment. Many ministers did not act, and changed one batch after another. It can be said that the whole court is corrupt. The economy has also declined, causing many people to rebel. Besides, there will be a new emperor in a few months. It can be said that the situation and the court are relatively turbulent.

In fact, it can be said that many emperors in the Yuan Dynasty were puppets, and the actual power of the imperial court was controlled by many powerful ministers, including the selection and appointment of ministers. At that time, there was a system that intensified contradictions, that is, the four-class system, which made the relationship between China and Mongolia worse at that time, which was a serious racial discrimination. At that time, Mongols were the noblest, followed by people of other races, which made the bottom people finally have to rebel, leading to frequent riots. This laid the groundwork for its demise.

Moreover, the war in the Yuan Dynasty never stopped, which made the soldiers weakened and unable to rest. Therefore, the long-term war is not only a disaster for soldiers, but also a disaster for the people, which has already doomed the end of the Yuan Dynasty.

Therefore, the demise of the Yuan Dynasty was mainly caused by the turmoil of the current situation, the chaos of the imperial court, and the ethnic hierarchy discrimination. In the final analysis, it is the inaction and chaotic management of the court.
