If the Jin Dynasty is counted in the Western Jin Dynasty and the Eastern Jin Dynasty, 155 years are not short, just to say that the Western Jin Dynasty is indeed a short-lived dynasty, 52 years are scattered like clouds, and it is not a well-known, vast history is like smoke. Counting up the Eastern Jin Dynasty and the Western Jin Dynasty, a surname Liu, simply has no half-cent relationship with Sima Shi, Sima Shi died in four generations, although it is calculated for more than 50 years, but the Eight Kings Battle has been played for 20 years, so the real recuperation is also 35 years, so the reasons for its short life are summarized as follows:
First: Sima Yi's bloody slaughter of Liao was too heavy to lay the foundation for future generations
Sima Yi could not have imagined in his dreams that he had been lying down for decades, enduring humiliation and burdens, and even saying that Sima Jiangshan, who had been pretending to be a fool and pretending to be a grandson, had been wiped out for decades, not knowing that everything in the world had cause and effect, perhaps he had killed too much to damage Yin Morality. In 237, Gongsun Yuan, the Taishou of Liaodong, established himself as a rebel, and Sima Yi led his troops to quell the rebellion, living up to expectations for more than a year and destroying Gongsun Yuan. It is said that after the counter-rebellion, it was enough to kill chickens and scare monkeys and behead the main participants to show the public, but Sima Yi did not do so, he directly beheaded all thousands of gongsun Yuan's men and built their corpses into "Jingguan"; at the same time, he also wantonly slaughtered the people, and the four places of Liaodong, Daifang, Lelang, and Xuanju were full of mourning, and there was almost no cooking smoke like a ghost town, and for a time the population of the Liaodong region was greatly reduced.
Two: The 80,000 chaos shook the foundation of the country
Sima Yan forced the Wei Emperor Cao Huan to take the throne in 265 and established a new regime. It was not until 280 AD that the Western Jin Dynasty eliminated the last regime of the Three Kingdoms, Eastern Wu, ending the war and chaos that had been torn apart since the end of the Eastern Han Dynasty, and reunifying China. After the Qin and the Two Han Dynasties, the Western Jin Dynasty was the fourth great unified dynasty in ancient times. Sima Yan, the Emperor of JinWu, succeeded in usurping the throne as a vassal of Cao Wei, but many of the ruling policies after the founding of the state laid the groundwork for the short-lived death of the Western Jin Dynasty. The regimes of Cao Wei and Sima Jia were both usurped, and there was no complete scripture to follow in the continuation of the state's civil rule and martial arts and policies. Sima Yan believed that the reason for the demise of the Cao Wei regime was because the kings of the Cao Wei regime had the name of the land in vain, but did not have the reality of social welfare, so that they died in isolation. Therefore, after Sima Yan established the state, he sealed 27 kings with the same surname, and stipulated the number of households and the number of leaders of the clan. However, the politics of the king of the clan was also a kind of decentralized politics as opposed to the centralized system, and with the continuation of the rule of the Western Jin Dynasty, the "Rebellion of the Eight Kings" of the king of the clan for the power of the central government eventually broke out, and the Western Jin regime quickly disintegrated in the infighting of the Sima clan. In the 16 years of the Eight Kings Rebellion, seven of the eight kings who participated in the war were killed, and the rest of the kings were also undefeated or dead, while the officers and men of the army and the people were even more uncountable, the social economy was seriously damaged, and the national strength of the Western Jin Dynasty was exhausted, allowing hidden class contradictions and ethnic contradictions to erupt.
Emperor Wu sima Yan used his talents improperly
It should be said that Sima Yan, the emperor of the Jin Dynasty, was also powerful enough, having 17 sons, some of whom died early, but Sima Yan chose Sima Zheng to be the successor, that is, Sima Zheng, the emperor of Jinhui. Sima Zheng was an idiot, and he had a famous saying: "Why not eat meat", it is said that at that time, there was a large-scale natural disaster in the country, many parts of the country were in famine, the people had no food to eat, and there were people who starved to death everywhere. When the ministers reported the disaster to him, Sima Zheng asked doubtfully, "Why don't you eat meat?" Therefore, Sima Zheng is actually a completely unreliable person, cowardly and incompetent, addicted to wine, and only knows how to have fun. The most terrible thing is Sima Zheng's wife Jia Nanfeng, who is a well-known poisonous woman. After Sima Zheng came to power, he trusted his empress Jia Nanfeng very much, so Jia Shi was able to monopolize power. Jia Nanfeng has always been regarded as a typical negative figure in the harem chaos, who is fierce and tyrannical, and his methods are often cruel and extreme, so that he later caused the clan and foreign relatives to fight for power and profit, and was the culprit of the "Rebellion of the Eight Kings" in the Western Jin Dynasty.
