What was the regime change in the Southern and Northern Dynasties before Sui Dynasty?

The Political Structure in the Southern and Northern Dynasties

We know that the Northern and Southern Dynasties inherited the pattern of sixteen countries in the Eastern Jin Dynasty. During the Three Kingdoms period, the Western Jin Dynasty achieved great unification, but this situation was short-lived. With the occurrence of the "Five Disorders", the north fell into the hegemony of "five lakes and sixteen countries", and the Jinshi nobles who migrated to the south also established a new regime in the south, which was called the Eastern Jin Dynasty in history. It can be seen that with the demise of the Western Jin Dynasty, the northern part of the Central Plains was a minority regime for a long time, while the southern part was a Han regime. This time is not just a prelude to the Northern and Southern Dynasties. Until AD 420, Emperor Wudi of the Eastern Jin Dynasty usurped the position of the Eastern Jin Dynasty and established the first dynasty of the Southern Dynasties by virtue of his military achievements in destroying Southern Yan and the later Qin Dynasty? Liu Song. At this point, it officially entered the Southern and Northern Dynasties with frequent regime changes.

Regime change and turmoil in that southern dynasty

As the first dynasty in the Southern Dynasties, Liu Song was also the dynasty with the strongest national strength and the widest territory in the Southern Dynasties. Due to the usurpation of imperial power, this involves the overall crisis of imperial power politics, and there have been waves of clan struggles and frequent civil wars, and large areas of territory have also been lost. Finally, Xiao Daocheng usurped the throne and established Nanqi. The same thing happened in Song Dynasty because Qi and Qi did not solve the internal contradictions of imperial power. At the same time, Qi's politics is also very chaotic. Soon, as a cousin, he usurped the throne and changed his country name Liang. Although Xiao Yan was good at governing politics and designed many political measures, which made the Liang Dynasty prosperous for a short time, the contradictions accumulated by the previous generation were not solved. Finally, Xiao Liang collapsed in the Hou Jing Rebellion. Instead, it was the Chen Dynasty established by Chen Baxian, a Vietnamese from Lingnan, which was finally destroyed by Sui.

Regime change in North Korea

Earlier, we talked about the regime change in the Southern Dynasties. Now let's talk about the Sixteen Countries in the Northern Dynasties. The Northern Wei Dynasty, founded in 386 AD, was the ultimate winner of the sixteen countries' hegemony. In 439 AD, the North was unified, and a large area of land in the South was seized. Then came the famous reform period of Emperor Xiaowen of the Northern Wei Dynasty. As a result of a series of sinicization measures, the country developed rapidly, but it also offended Xianbei people in the northern frontier. After the Xianbei people fought back, two groups kidnapped an emperor of the Northern Wei Dynasty and established the Eastern Wei Dynasty and the Western Wei Dynasty. The Eastern Wei Dynasty was later usurped by the reigning Gao and established in the Northern Qi Dynasty. The Western Wei Dynasty was usurped by Yuwen, who was in power, and was established in the Northern Zhou Dynasty. Because the degree of sinicization in the Northern Zhou Dynasty was higher than that in the Northern Qi Dynasty, the Northern Qi Dynasty was finally eliminated. Very dramatically, Emperor Wendi, the consort of the Northern Zhou Dynasty, replaced the Northern Zhou Dynasty to establish the Sui Dynasty, and achieved great unification after the elimination of Nan Chen.
