At the end of the Eastern Han Dynasty, the princes recruited troops to revolt, and Cao Cao, as one of the first princes to recruit troops and buy horses, took the lead in future wars, and Cao Cao also became one of the most powerful princes. In the process of Cao Cao's continuous achievements, his status in the Han Dynasty court also became higher and higher, and finally his son Cao Pi replaced the Han Dynasty and established the Wei Dynasty. However, Cao Wei's strength was very strong, and Eastern Wu and shu were not his opponents, so why could they be easily usurped?
1. The monarch of the State of Wei was soon to die
As we all know, Cao Cao, as a generation of tyrants, was very positioned and capable of leadership, and was very cunning and treacherous, and did not trust others. In his old age, the headache was very serious, Cao Cao summoned the famous doctor Hua Tuo, Hua Tuo to do surgery to help Cao Cao remove the tumor in the head, but Cao Cao did not believe Hua Tuo, and killed him, so Cao Cao's illness became more and more serious, and he did not even see it on the day of the establishment of the State of Wei.
His son Cao Pi, as a monarch who was very reassuring to Cao Cao, tried his best to govern during his reign, but he did not live long, and died after only six years on the throne. Cao Pi's son Cao Rui did not live up to Cao Pi's trust, and during his reign, the State of Wei developed rapidly and achieved success in foreign wars, but he died after only thirteen years on the throne.
After Cao Rui's death, only the little emperor Cao Fang succeeded to the throne, Cao Fang became emperor at the age of eight, such a small emperor was a puppet in the imperial court, so the political struggle of the imperial court became more and more serious, and the short reign of Cao Pi and Cao Rui also made the politics of the imperial court more unstable, so the short life of the monarch was one of the important reasons for the fall of the Wei state.
Second, the Wei state was constantly in turmoil
The State of Wei inherited the national framework of the Han Dynasty, and its geographical location and soil environment were very superior, as a country in the plain, there were two neighbors around it, the State of Wu and the State of Shu, the pressure was still very great. Therefore, the court of the State of Wei was often disturbed by these wars, and some people who plotted against them could continue to obtain military merit through the way of war and enhance their power in the imperial court.
3. Misuse of traitors
During Cao Cao's time, there was the Sima family that had been following Cao Cao in his eastern expeditions to the west, so Cao Cao's contribution to Sima Yi was also full of praise, even so, Cao Cao still did not trust Sima Yi, and he saw through Sima Yi's careful thinking. Therefore, before cao cao died, he told Cao Pi that Sima Yi had different intentions and could not reuse him. However, Sima Yi deceived Cao Pi through his hypocritical appearance, and Cao Pi believed that Sima Yi had worked hard and achieved great feats, so he promoted Sima Yi to be an extremely popular subject.
Before their deaths, Cao Pi and Cao Rui both regarded Sima Yi as a trusted lonely subject, so that the status of the two dynasties' trusted orphans in the imperial court could be imagined, and even if they were old, they could provide an umbrella for his subordinates. Therefore, Sima Yi provided great help to his family during his reign, which also allowed Sima Zhao to have a place in the imperial court. After Cao Fang took office, Sima Zhao's ambitions were exposed, and as Sima Zhao's power grew, the State of Wei was changed shortly thereafter and the state was destroyed.
In general, although Cao Wei was very powerful, the interior had been corroded clean, and even if they were beautiful on the surface, they could not escape the result of being destroyed in the end.
