Jin Dynasty: It is divided into two periods: Western Jin and Eastern Jin. The Western Jin is one of the unified dynasties in Chinese history, and the Eastern Jin is one of the six dynasties. The two Jins have a total of 15 emperors, a total of 154 years.
Sima Yan ended the era of the Three Kingdoms dispute and completed the reunification. After experiencing the rebellion of the Eight Kings and the disaster of Yongjia, the country gradually declined. In 316, the Western Jin Dynasty was destroyed by the northern barbarians. In 317, the royal family of the Western Jin Dynasty crossed the south of the Yangtze River, and Sima Rui continued the Jin Dynasty at Jianye. It is known as the Eastern Jin Dynasty. The Eastern Jin Dynasty has made several northern expeditions to the Central Plains. After the battle between the Eastern Jin Dynasty and the former Qin Feishui in 383, it was temporarily consolidated. During the Jin Dynasty, the Han people who moved from the north to the south brought advanced technology to the south of the Yangtze River and further developed the south of the Yangtze River. In 420, Liu Yu established Liu Song and the Eastern Jin Dynasty fell. Chinese history has entered the Southern and Northern Dynasties.
The Jin Dynasty experienced its final demise in 154 years, and 15 emperors appeared. Why did the Jin Dynasty not appear in the prosperity of the Han and Tang Dynasties? And it has always been in the chaos of war and court disputes. What caused the ultimate demise of the Jin Dynasty? Where is the root cause?
1. The emperorβs mediocrity and cruel enslavement Since the establishment of the Western Jin Dynasty, it has lost the vitality of the new dynasty. The rulers are all generations of high officials and nobles, and they bullied the people. No mercy, and agricultural taxes were more onerous than those in the Three Kingdoms period. Jinwu Emperor Sima Yan even indulged this evil. The founding emperor did not do it well, let alone the latter, which also caused the corruption of the imperial court. Regardless of the people of the Han nationality or the Hu nationality, these high-ranking officials and nobles all showed their own oppressive ability, which can be imagined in the situation of the people at that time.
δΊγ The real power of the princes was over. The Da Sima Yi and Sima Zhao family were able to usurp Cao Wei Jiangshan, and because the strength of the Cao Wei clan gradually weakened, they could not treat Sima. The family formed a check. Not long after the Emperor of Jin Wu, Sima Yan became emperor, he named his ancestor Sima Yi and his descendants under the clan as kings, taking the county as the country, the 20,000 households in the Yi as the big country, and the upper, middle and lower armies; There are three thousand soldiers in the upper and lower army; five thousand households are a small country with 500 soldiers. The knighthood is hereditary and monopolizes the local official position. In this way, the power of the local separatist rule gradually increases. This is also the direct cause of the "Eight Kings".
δΈγ The number of inland migration of Hu people has increased Since the Eastern Han Dynasty, with the split of the Huns, ethnic minorities in the west and north have begun to migrate inland. As early as the Cao Wei period, due to the perennial wars of the Three Kingdoms, which caused a rapid population decline, in order to supplement the shortage of labor, they often attracted and even forced ethnic minorities to relocate. The massive inland migration of ethnic minorities has led to a sharp increase in the number of northern Hu people, even surpassing the number of northern Han people. The massive inland migration of the Husbands and ethnic conflicts became more and more prominent, which paved the way for the subsequent "Five Husbands in China".
