Why were Sima Yi s descendants able to destroy the Three Kingdoms, but the Western Jin Dynasty was s

Sima Yi is very kind-hearted, uninhibited, has his own set of rules in the use of soldiers, is very smart, very cautious, and is frugal and humble to the monarch, colleagues and subordinates. But his descendants did not manage the country well, so the Western Jin Dynasty quickly perished.

Sima Yi did have the ability to strategize, but unfortunately, the descendants could not maintain the foundation he had laid, so they could only let the country go downhill, and finally the Western Jin Dynasty perished.

Sima Yi is a brave and resourceful person, otherwise how would he destroy the Three Kingdoms. It's a pity that the children and grandchildren are not strong enough, and they can fight but can't defend.

Sima Yi is a strategic, but his descendants can't protect the country for him, so they can only go with the flow and develop from the Western Jin Dynasty

As the saying goes, it is easy to fight the country and it is difficult to defend the country, Sima Yi does have strategy and ability, but it is a pity that the descendants cannot maintain the country he has built.

Sima Yi's status in the Three Kingdoms was very high, and he held great power in the Wei State. Because Sima Yi's father and son were very ambitious and wanted to be emperors, they wanted to usurp power.

Sima Yi. The reason why Gao was able to seize the power of the most orange tour was because of Cao Shuang's negligence, which was of course the main reason. All the power is controlled by the Sima family. And all this work is due to Sima Yi.

In the end, it is the emperor's incompetence, in the early stage of the Western Jin Dynasty, Sima Yan was strict with himself and vigorously developed national strength, which was a severe blow to waste! But Sima Yan reached the late stage and became extremely mediocre, and in the end, the Western Jin Dynasty was only 51 years old.

1: Winning the country is not right, and hidden dangers are buried. 2: Divide the kings. 3: Wrong choice of heir.

Sparse start, each generation of founding emperors is all cultural and martial arts, but the founding emperor of the Jin Dynasty, Sima Yan, although he has the credit of destroying Wu, but the title of "Emperor of Raising Cars" is more familiar to everyone, and it has been passed down for thousands of years, becoming one of the most lustful emperors in Chinese history. First, the country was not right, and hidden dangers were buried, and Liu Bang was divided into feudal kings, which led to the rebellion of the Seven Kingdoms, but the Sima family did not seem to pay attention to the lessons of the past. After Sima Zhao destroyed Shu in 264, he began to divide the feudal kings with the same surname.

At that time, Cao Wei was still alive, so the highest title of the feudal was "Gong", which was lower than Cao Wei's "Wang", but the scale of the fief was comparable.

The emperor had no talent, and the empress controlled the government, which led to the misery of the people of the country.

Because the emperors of the Sima family were worse than the other, and later there were fools who became emperors and married a poisonous queen Jia Nanfeng, which made the internal chaos of the Western Jin Dynasty, and the Western Jin Dynasty only existed for a few decades before perishing.

Because Sima Yan's son Sima Zhen was mentally handicapped, he gradually fell into power, and the Eight Kings Rebellion occurred, and the northern ethnic groups took advantage of the situation to destroy the Western Jin Dynasty.

Let me give you my personal opinion.

The main driving force behind the demise of the Western Jin Dynasty was the internal migration of ethnic minorities. However, the indirect reason is the "Rebellion of the Eight Kings" after Emperor Wu of the Western Jin Dynasty, and the mutual attack of the internal clans seriously consumed the national strength of the Western Jin Dynasty. When the ethnic minorities who entered the Central Plains raised the banner of resistance, they were unable to suppress it, which led to the fall of the Western Jin Dynasty.

The fuse of the "Rebellion of the Eight Kings" was that Sima Yan, Emperor Wu of the Jin Dynasty, failed to make arrangements when choosing the heir to the throne, which led to frequent contradictions in the core of the ruling and could not be reconciled. At that time, Emperor Wu of Jin, who was eloquent and strategic, was faced with a serious problem: there was a fault line in the heir to the dynasty!

Among his sons, the only one who is the eldest is Sima Zhen, but this emperor is notoriously dull in history and is not suitable to be an emperor at all.

But this one gave birth to a very smart Sima Shu [read: yù], who loved this emperor grandson Emperor Wu of Jin very much, and if he wanted to make his grandson emperor, he must let Sima Zhen succeed to the throne first, and after weighing, he still chose this dull descendant as the heir to the throne.

However, in the face of the stable world left by Emperor Wu of Jin, Sima Zhen still failed to defend it. The powerful people competed for the supreme ruling power of the dynasty, and the vassal kings of various places organized large armies for this purpose and fought directly by force!

Why did a vassal king have such a large army? During the reign of Emperor Wu of the Jin Dynasty, in order to restrain the scholars, he made the sons of the clan kings and gave them the right to own the army. They can rely on the military to obtain huge human and material support in the land.

When they saw that the emperor Sima Zhen was dull and the capital was controlled by people with intentions, these people from the clan saw an opportunity.

At that time, a large number of people from the clan participated in this contest, mainly eight people, and called it the "Rebellion of the Eight Kings". It lasted for 16 years, exhausting the national strength of the Western Jin Dynasty, and it was no longer possible to control the entire dynasty in the later period.

The Western Jin Dynasty dissipated in this turmoil, and Sima Rui, a member of the clan, went south to the south of the Yangtze River and established the Eastern Jin Dynasty in the southeast.

Because this emperor did not govern the country well after seizing the throne, but coveted beauty all day long, and his subordinates did not do things seriously.

Because they didn't want to do everything in one go, they all thought of what to do, they didn't have a plan at all, and they didn't have enough preparation. So it led to a quick demise.

Personally, I think the reason why the Western Jin Dynasty fell so quickly was because the internal and external environment they faced at that time was too bad, so it was like this.
