Cao Wei, created by Cao Cao, will be replaced by Sima Yi, what is the root cause of this?

Because Cao Cao stood on the opposite side of the family. Cao Wei has always suppressed the family, and Sima Yi is the leader of the family's rebellion against Cao Wei.

Military power was handed over to outsiders. At the end of the Wei Kingdom, the military power was in the hands of Sima Yi, and the Cao family still didn't trust Sima Yi, forcing Sima Yi to rebel.

Cao Wei was replaced by Sima Yi, which has a lot to do with the lack of ability of Cao Cao's descendants, and the three generations of Cao Cao's grandchildren only know how to show grace to Sima Yi, but do not know how to control, and reuse Cao Shuang and Sima Yi from beginning to end.

Digging graves and digging graves will break the longevity of the yang, and the descendants will not live long. The contradictions are all between the living, and Xiahou Zhucao has become a dead person, so there is no contradiction.

It was because Sima Yi's army was still relatively strong at that time. And many people love Sima Yi, if you get rid of him, it may damage Cao Cao's reputation.

Because although Sima Yi has different intentions, he is indeed talented, and Cao Cao also has a heart to cherish talents.

Cao Cao felt that there was no need for this, and he also felt that it was a kind of training for himself and a kind of help for himself.

1.Sima Yi was not allowed to take power2supported the balance of other scholars, this policy was actually effective, and in the end of the Jin Dynasty, the emperor and the gate lord ruled the world together, and the ruling power was not strong, and it was a miracle that Cao Wei lost the country.

Sima Yi in history is still very trusted by Cao Pi. Moreover, Sima Yi did not hold much power at that time, and his influence in the imperial court was not great. Although the history books record that Cao Cao told Cao Pi to be wary of Sima Yi in his later years, this is likely to be a subsidiary of later generations, not real history.

A person's growth is carried out step by step, and it is impossible for others to reach a person's future by taking one step at a time.

At that time, Cao Pi left three people to prevent Sima Yi from rebelling, but he didn't expect Sima Yi to live a very long life, and all three of them died before Sima Yi, so Sima Yi finally seized the power of Cao Wei.

The most important point is that Cao Pi gave Sima Yi a high status, but did not give him actual power, let alone military power. Throughout Cao Pi's life, Sima Yi's status was a high-level staff division-type figure.

Cao Pi specially found three people to check and balance Sima Yi, hollowing out Sima Yi's real power and putting Sima Yi in an embarrassing position, but he still did not stop Sima Yi's rebellion.

Cao Pi appointed several people to restrain Sima Yi and disperse Sima Yi's power, which achieved the effect of balancing Sima Yi and leaving Sima Yi in a state of being hollowed out.

Divide the rights of the other party, increase the rights of the other party, and promote a few people to balance Sima Yi, so that he can better maintain his rule.

The main reason for this is that the Sima family is too large, and whether it is Sima Yi or Sima Yi, or later Sima Zhao, they are all concentrating on planning, so this situation will happen.

Because Sima Yi was ambitious and wanted to usurp power, he had been being attracted from behind his back, cultivating power, and finally when the time was ripe, he won the world.

Cao Wei's military power was in the hands of Sima Yi. Cao Wei's descendant was weak and incompetent, and had no real power, he was just a puppet of the Sima family, and he would be replaced at any time.

Military power fell into the hands of Sima Yi. At the end of the Wei Dynasty, the Cao family did not have too famous military strategists, their abilities were insufficient, and the military power fell into the hands of Sima Yi, so Sima Yi was able to successfully rebel.

Because Cao Cao went to the opposite side of the family, suppressed the family, and promoted the children of the poor family. For the sake of their own future interests, the Maison can only choose to replace it.

The Sima family was a famous family at that time, and Cao Cao also stated on his deathbed that he wanted to guard against Sima Yi, so the descendants of the Cao family have been pressing the Sima family, and after a long time, Sima Yi launched the Gaopingling Rebellion under the water of the family.

Because Sima Yi was too forbearing, the main root cause was that the later monarchs of Cao Wei relaxed their defense against Sima Yi, so that Sima Yi could succeed.

Because after the death of Cao Cao and Cao Pi, no one in the Cao clan could suppress Sima Yi, Sima Yi has always pretended to have no desire for Cao's power, and this scene has been played for decades, and Sima Yi finally seized power after Cao Pi's death.
