The Jin Dynasty ended the troubled times of the Three Kingdoms and established a feudal dynasty with unified world. But there is no detailed record of this dynasty in history. The fundamental reason is that the Jin Dynasty formed a unified world in a short time, the Western Jin Dynasty split after Sima Yan and Sima Zhong, and the Eastern Jin Dynasty only occupied half of the country, which was not a feudal unified dynasty at all, so the Jin Dynasty had a very low sense of existence in history. The history of the Jin dynasty is really nothing, basically in a state of extreme chaos, and compared with other feudal dynasties, it has little effect on promoting social progress.

After several generations of efforts, Sima Jia finally established the Jin Dynasty. After the destruction of Wu, it declared the end of the Three Kingdoms era and the arrival of the Jin Dynasty era. Sima Yan was the first founding emperor of the Jin Dynasty. Sima Yan experienced numerous political and military struggles in his life. Among them, Sima Yan really became a generation of emperors. He has the political ability to control the country and the ability to control ministers.

But Sima Zhong, the next heir of Sima Yan, is not the emperor. He is a famous bad king in history. If he wants to govern such a huge country, he must have high emotional intelligence and IQ, which Sima Zhong does not have. Sima Yan knew that Sima Zhong could not control such a huge country, so he left several ministers for Sima Zhong before he died. Although these assistant ministers can help Sima Zhong deal with the failure of state affairs, they also pose a serious threat to Sima Zhong's position, and all the power belonging to the emperor is allocated to several assistant ministers. They gradually eroded Sima Zhong's power and became the fuse of the Eight Kings Rebellion.

The rebellion of the Eight Kings was the turning point of the Jin Dynasty from prosperity to decline. The emperor of the Jin dynasty also fell from the altar, forming a local separatist situation throughout the country. After the Eight Kings Rebellion and the Five Rebellions, the story of the Western Jin Dynasty ended here.
