Looking at the history of the Chinese nation's feudal dynasties for thousands of years, each dynasty and each generation has a variety of intricate reasons from prosperity to demise. From the establishment of the Qin Dynasty to the end of the Qing Dynasty, hundreds of emperors were born, nine great unified dynasties, and although the Song Dynasty was controversial in history, let's take it in here. The reasons for their demise are complex, but they are also inseparable from the following factors: the dictatorship of eunuchs, peasant uprisings, the dictatorship of foreign relatives, the dictatorship of harems, and the subjugation of foreign nations.

?? The first thing to talk about is the Qin Dynasty, the first feudal dynasty in Chinese history, and it is also a rare short-lived dynasty in Chinese history, from qin shi huang destroying the six kingdoms as emperor to Liu Bang leading the army into Xianyang City, which lasted fifteen years. The reasons for the demise are thought-provoking, the most important being the two eunuch dictatorships and the peasant revolt, and the first dynasty in which the eunuchs came to power was the Qin Dynasty. Before his death, the first emperor of the Qin Dynasty, Ying Zheng, originally wanted Fu Su to ascend the throne as emperor, but he did not expect that Zhao GaoLisi conspired to tamper with the edict, and the murder of Fu Su Mengtian and others was not said, so that Hu Hai succeeded to the throne sounded the death knell of the demise of the Qin Dynasty. Originally, the young Hu Hai let Zhao Gao control the government of the dynasty, and once the eunuch party controlled the government, there was bound to be an accident in that country, and it was not long before Chen Sheng and Wu Guang broke out in Daze Township, although they were suppressed later. However, at that time, it gave the confidence of the Six Kingdoms of Shandong to restore the country, so uprisings broke out in other places one after another, and the Qin Dynasty was difficult to support even if the military strength was strong, and eventually the Qin Dynasty collapsed.
?? The second thing to say is the Han Dynasty, everyone knows that the Han Dynasty is divided into the Western Han Dynasty and the Eastern Han Dynasty, and the reason for the demise of the Western Han Dynasty is the dictatorship of the harem, so that Wang Mang usurped the Han Dynasty to establish a new dynasty, and he was a relative of the empress dowager Wang Zhengjun at that time. On the eve of the fall of the Eastern Han Dynasty, there was also a harem dictatorship, but it was not as serious as the Western Han Dynasty, and the final cause of the demise was the eunuch dictatorship, which caused the Zhangjiao rebellion, He Jin lured the wolf into the house, and the Western Liang army Dong Zhuo led the Tianzi to order the princes, of course, everyone knows that the Han Xiandi was controlled by Cao Cao, and the power and arrogance of the eastern Han Dynasty were eventually replaced by the State of Wei.
The end of the Three Kingdoms era was the Jin Dynasty, which was divided into the Western Jin Dynasty and the Eastern Jin Dynasty, and the Eastern Jin Dynasty could not be regarded as a unified empire, and finally the Jin imperial family was killed by Liu Yu. The reason for the demise of the entire history of the Western Jin Dynasty for several decades is thought-provoking, and the rebellion of the Eight Kings and the various kings of the various clans attacked each other and killed each other. The Rebellion of the Eight Kings eventually led to the Wuhu Rebellion and the fall of the Western Jin Dynasty. Look, he died under foreign rule and was destroyed by Wuhu.
After the Jin Dynasty, after hundreds of years of great turmoil, after the unification of the Sui Dynasty, it was the second short-lived dynasty in Chinese history after the Qin Dynasty, although it only existed for a few decades, which was of great significance to future generations. The Sui Dynasty Emperor tyrannically opened the Grand Canal to requisition a large number of laborers and eventually the people's resentment was rife, and the Sui Dynasty perished in the call of the peasant army's uprising!
The Tang Dynasty after the Sui Dynasty was a famous prosperous dynasty in Chinese history, and the Tang Dynasty went through the rule of Zhenguan, the rule of Yonghui, the reign of Kaiyuan Shengshi and other national strengths to the peak, but the Anshi Rebellion suddenly beat the Tang Dynasty to the prototype, and gradually formed a situation of division of local feudal towns, and in the middle and late period eunuchs began to control the government. Therefore, the demise of the Tang Dynasty first came from internal eunuchs, and the second was that the various regions made the supporters respect themselves.
?? The Tang Dynasty was followed by the Song Dynasty, which learned the lessons of the fall of the Tang Dynasty and established many political systems that better avoided the usurpation of the throne by the powerful subjects, but because the border defense was too weak, it eventually led to the fall of the Northern Song Dynasty and the Southern Song Dynasty to foreign regimes twice. Of course, there was a peasant uprising at the end of the Northern Song Dynasty, but the suppression was successful.
After the Song Dynasty, the Yuan, Ming, and Qing dynasties died in the midst of official corruption, usurpation of the throne by powerful subjects, and peasant uprisings, and the Ming Dynasty was the factory guard system in the middle and late period, and eunuchs always controlled the government of the dynasty, becoming an inevitable factor in the demise of the Ming Dynasty. There was also a bit of natural and man-made disasters, and eventually the Ming Dynasty was destroyed by the Dashun regime. The first impression of the later Qing Dynasty was the dictatorship of the harem, which was the main reason for the demise of the later, Cixi was the culprit in that era, of course, there were some peasant uprisings of greater or smaller sizes, fortunately, the Xinhai Revolution broke out and ended the rule of the Qing Dynasty.
