During the Three Kingdoms period, the three legs stood tall, and all the forces had the desire to dominate, but because of their equal strength, they were divided from each other for a long time. In the end, sima Yan of the Western Jin Dynasty became the one who had the ability to unify the world. Sima Yan's grandfather was Sima Yi, who was once a loyal vassal of Northern Wei and made outstanding contributions to the development of the State of Wei.
Sima Yi played a pivotal role in the history of the State of Wei, cao pi was the founding emperor of the state of Wei, but Cao Pi died young, so in order to consolidate his own inheritance, he entrusted the new emperor to the four courtiers at that time, including Sima Yi. After Cao Rui succeeded to the throne, he died not many years later, all three sons died prematurely, and his own concubines were also occupied by others.
First, Cao Pi is lonely
During the Three Kingdoms period, there is a very classic story of the orphan, before Liu Bei's death, the White Emperor Chengtuo orphan entrusted his son and the great cause of Shu Han to Zhuge Liang, originally the burden on Zhuge Liang's body was not so heavy, but Zhuge Liang accepted his entrustment before his death in order to meet Liu Bei's wishes, even if he assisted a generation of Emperors, but he also ran for the great cause of Shu Han.
In the same period, the State of Wei also had the emperor's death, the first thing the emperor did before his death was to choose a successor, Cao Cao Liu Bei in the Three Kingdoms period was a top hero Haojie, but their descendants were very ordinary. Cao Pi usurped the throne, and when he died, he did not know who to pass the throne to, and finally had no choice but to learn from Liu Bei and begin to entrust himself.
Cao Pi thought very well, although Cao Rui's talent was not very clever, but it would not be too much of a problem to choose a few good orphan ministers, support each other and teach well. Therefore, Cao Pi chose four people to become the ministers of Tuogu, namely Sima Yi, Cao Zhen, Cao Xiu, and Chen Qun. Although these four people all had a high status in the State of Wei, they balanced each other.
Before Cao Pi left, he actually thought very thoughtfully for Cao Rui, after all, it was the young lord who ascended the throne, and he certainly could not grasp the power of the court quickly, so he chose the four people with the most weight in the court to entrust the orphan. None of these four people could seize power as a single family, and as long as the status of the four people was the same, they would not pose too much threat to the throne, and each of them would help Cao Rui manage the government.
After Cao Pi's death, the situation did develop in the direction he expected, although Sima Yi was a great general, but Cao Zhen and Cao Shuang's combat effectiveness was not weaker than his if they cooperated, and although Chen Qun had some advantages in the court, Sima Yi could also compete with it. In this way, they checked and balanced each other and helped Cao Rui consolidate his power.
Second, Cao Rui is lonely
After Cao Rui ascended the throne, with the help of four entrusted ministers, he smoothly managed the imperial government, although he was useless but also blameless, and he was still a qualified emperor. But because he was too constrained by the four ministers, he did not release too many of his own views, so in the later period he was smoothed out, no ambition, and arbitrary.
Especially in the late period, he ordered people to overhaul the palace, and everything was particularly luxuriously decorated, but this process consumed a lot of financial and material resources, resulting in the deficit of the imperial treasury. This had already affected the foundation of the State of Wei, and by this time Cao Rui's body was already in trouble, and he ignored the persuasion of others and made a willful decision according to his own wishes.
Cao Rui's body was worse than a day, his reign was very short, and his body gradually deteriorated after not many years as emperor. At this time, he also wanted to learn from his father and choose the ministers in the court to be entrusted, so as to ensure that the important ministers in the court did not have the intention of usurping power, and also quickly assist the new emperor. Later, Cao Rui decided to choose Sima Yi and Cao Shuang as the ministers of Tuoguo.
In order to improve Cao Shuang's position, Cao Rui also promoted Cao Shuang to a general before his death, so that the two people had the same official position and could balance each other. Originally, the previously selected ministers were Xiahou Xian and Cao Zhao, but Cao Rui, because he listened to the advice of others, later decided to choose Sima Yi and Cao Shuang. Originally, Xiahou Xian and Cao Zhao were both members of the Cao Wei Sect's office, but Cao Rui was not reused.
During Sima Yi's reign, only political titles were not included in the external military rank, that is to say, Sima Yi could not participate in politics, and Cao Rui was also to prevent Sima Yi from gaining the throne, so he was always wary of him. Later, when he died and was entrusted with isolation, Cao Rui also chose a military general and a courtier to balance each other, but he did not expect that Sima Yi's later development was too big to check and balance.
Third, the most miserable emperor Cao Rui
When Cao Rui was alive, he was still able to balance these meritorious ministers, but once he died, the court was in turmoil, which gave these people the opportunity to usurp power and rebel. Sima Yi's power also grew larger and larger, and gradually became the real center of power in the State of Wei. Cao Zhen colluded with Sima Yi to become the true ruler of the Wei state.
Cao Rui can be said to be the most miserable emperor, because Cao Rui had three sons who all died early, and all of them died after being crowned king, Cao Rui and two daughters also had an extremely tragic fate, the eldest daughter also died early, and the second daughter died early after marrying, and then married several people. Even Cao Rui's adopted son did not succeed to the throne and died prematurely.
After Cao Rui's death, Cao Shuang occupied the initiative of the court, he and Sima Yi jointly grasped the government, Cao Shuang also took the concubines in the harem as his own, and did whatever he wanted in the palace, and no one could control him. The concubines in Cao Rui's harem all became Cao Shuang's concubines for a while. Soon after Cao Rui's death, Sima Yi took the lead in usurping power and made his son Sima Zhao king.
Later, Sima Yi's grandson, Sima Yan, accepted the Zen throne of Emperor Wei as emperor and changed the name of the state. Later, with the efforts of Sima Yan, he unified the world and broke the situation of the Three Kingdoms. All this was also the reason why Cao Rui's chancellor was chosen by mistake, which allowed Sima Yi and Cao Shuang to control the government.
summary
Sima Yi experienced the Three Dynasties of the State of Wei, and can be said to be the elder of the Three Dynasties, and was a great general who fought everywhere at the time of Cao Pi. During cao rui's reign, although not reused by cao rui, he was still the most prestigious general of the Wei dynasty. The Third Dynasty was even more entrusted by Cao Rui, and it was at this time that Sima Yi seized the opportunity to take power into his own hands.
Cao Rui was really the most miserable emperor in the Three Kingdoms period, not only his own son failed to succeed to the throne, even the chosen descendants of the clan were also overshadowed by Cao Shuang and Sima Yi, three sons and a daughter all died prematurely, and his wife was occupied by Cao Shuang, Cao Rui was indeed the most tragic emperor in the Three Kingdoms period.
