Friends who know the Three Kingdoms know that Sima Yi finally succeeded in defeating Cao Shuang with his own wisdom and became the de facto ruler of Cao Wei. However, when Sima Yi seized power, why did those Cao clan relatives and the old clans not have a strong resistance.
This has to start with the situation at that time. Before Cao Rui's death, Cao Fang was still very young, and Cao Rui was also very afraid that the power would fall into the hands of Sima Yi, so Cao Rui would rather fall into the hands of the chancellor than be controlled by the sima family. Therefore, before Cao Rui's death, there were five candidates for the chancellor: Cao Yu the Prince of Yan, Xiahou Xian, Cao Shuang, Cao Zhao, and Qin Lang. Obviously, the people on this list are all relatives of the Cao family, and although this Qin Lang is not surnamed Cao, he is Cao Cao's adopted son, and there is no difference between him and his clan relatives.
And Sima Yi seems to have run out of drama, but there are two people who surprised them, that is, Liu Fang and Sun Zi. They were also very senior in Cao Wei, and although Sima Yi did not form gangs, his relationship with these two was very good. However, the clan relatives of the Cao family looked down on them a little, so the two still hoped that Sima Yi could become a minister of gu orders. Therefore, when Cao Rui was seriously ill, Liu Fang asked Cao Rui what he meant, and Cao Rui directly replied that he would let the King of Yan assist the government.
But Liu Fang was extremely clever and knew where Cao Rui's weaknesses were, so he told Cao Rui that the King of Yan flirted with your concubine when he was seriously ill, and he was still in the south of the city. Liu Fang's words of adding oil and vinegar made Cao Rui very dissatisfied with these people. Finally, Liu Fang said: Now that the crown prince is young, does His Majesty intend to hand over the sheji to these mediocre people? This sentence also said that Cao Rui's heart was on the ground. Indeed, Cao Rui also knew that these people had mediocre qualifications and had no talent at all, and he only hoped that they could protect the Cao family's social welfare.
However, Liu Fang's words made him dissatisfied with those people, so he asked who was more suitable. Liu Fang did not directly nominate Sima Yi, because it was useless to do so, but first said Cao Shuang, and Cao Rui did not have any objection to Cao Shuang, because he was originally one of the candidates, and then Liu Fang said Sima Yi. However, Sima Yi did not directly assist Cao Fang, but assisted Cao Shuang. In this way, under their flickering, Cao Rui also agreed.
Then Sima Yi began to move steadily again, and Cao Shuang did not have any foundation at first, but after becoming an auxiliary chancellor, there were more people who befriended him, and Cao Shuang was also a little drifty. Soon the Cao Shuang Clique, which monopolized power, was established, but with the establishment of the Cao Shuang Clique, some people were also excluded, and these excluded people had to rely on Sima Yi, such as Jiang Ji and others who became members of the Sima family. Then Cao Shuang wanted to intervene in Sima Yi's military power, but Eastern Wu did Sima Yi a favor and made trouble for Cao Wei, and at this time the war could only rely on Sima Yi, so he had to give Sima Yi an edict to transfer troops.
Later, under the persecution of Cao Shuang, Sima Yi always adopted the method of concessions. However, in the Chinese New Year's Eve of the ninth year of the first year, Sima Shi brought back a message: the young emperor Cao Fang would worship GaoPingling on the sixth day of the first month of the following year, and Cao Shuang, Cao Xi, and Cao Xun would accompany them! This was a very rare opportunity, so on this day, Sima Shi and Sima Zhao occupied a more critical position in the capital with the recruited dead soldiers, and Sima Yi directly entered the palace with the group of courtiers to get the Empress Yi's will, it can be said that this action became legal.
However, one of Sima Yi's subordinates, Huan Fan, left Luoyang at this time to report to Cao Shuang. It's just that he bet on the wrong chip, although Cao Shuang has a son in hand, but obviously does not want to fight with Sima Yi, so under Sima Yi's coercion and inducement, Cao Shuang plans to go back to be his own rich man. However, Sima Yi obviously did not give him this opportunity, and after he surrendered to Beijing, the backbone of the Cao Shuang clique was wiped out, and since then most of the Cao family's strength has been destroyed, and the Sima family has fallen to the opposition.
