In the tenth year of the reign of King Wei of Wei (249 A.D.), Sima Yi and other Cao Wei vassals took advantage of the monopoly cao shuang and emperor Cao Fang to go to Gaopingling to worship their ancestors, launched a coup d'état in Gaopingling, eliminated Cao Shuang's party, took the opportunity to kill more than 5,000 of Cao's clan relatives, and seized control of the imperial court. History is known as the change of GaoPingling. This coup d'état was a turning point that had a huge impact on the fall of the Cao Wei regime and the birth of the Jin Dynasty.
In fact, Cao Fang, the nominal monarch, was just a puppet in the hands of the great general Cao Shuang during the Coup d'état in Gaopingling! He did not have the ability and appeal to command his subjects, and even if he made a decision, Cao Shuang and his men would not obey. Therefore, when the coup d'état occurred, Cao Fang had to follow Cao Shuang's claim. However, Cao Shuang, the great general, was actually a straw bag, and he did not have the ability to control the fate of the Cao family at all, and in the end, not only did he not dare to take risks to confront Sima Yi, but obediently surrendered after being seduced by Sima Yi's sweet words.
The court ministers are bound to choose sides with it - if they either choose Sima Yi, they choose Cao Shuang, and no one will choose a "Son of Heaven" who has less to do more! Under these circumstances, Cao Fang, as an emperor, could not even measure his own team, so who had the ability to grasp the government and intimidate the subjects? In the drama of the Gaopingling coup, Cao Fang, who has no real power at all, cannot show anything. He can only go with the flow and wait for the fate to arrange!
In short, the change of Gaopingling was a fierce competition between various forces, according to the analysis of the data, Sima Yi did not launch a coup d'état alone, but the joint behavior of the entire imperial court minister and the foreign forces of the empress, but this coup really allowed Sima Yi to steal the results, control the government, and really affect the development of future history.
