I hope it will help you: 1. The biggest danger of the dynasty since the summer is rebellion. The five dynasties * * * directly died in rebellion. 2. Secondly, the peasant uprising. Only two people died directly in the uprising, and three people died indirectly in the uprising. In other words, there were not many successful peasant uprisings in the history of China, but they could shake the foundation of the dynasty. When there was rebellion within the ruling clique after the peasant uprising, the demise of this dynasty was inevitable. This is that rebellion is the most dangerous dynasty. It should be pointed out that historians agree that it is debatable that Qin died in the peasant uprising. Chen Sheng and the uprising were the fuse, while the Chu aristocrat Xiang, Qin grass-roots officials Liu Bang and Xiao He were the main political forces to overthrow the Qin Empire. The same was true at the end of Sui Dynasty. Only Song Dynasty died directly from aggression. First, the second emperor was captured by Jindu, and finally he died in Yuan. Although Jin died in the Five Rebellions in the Central Plains, the main reason was civil strife, that is, the rebellion of the Eight Kings. 4. From the historical trend, since the Western Jin Dynasty, the external pressure for the survival of the Chinese nation has gradually increased. During the Northern and Southern Dynasties, foreign forces did not establish a unified central government. However, after the Song Dynasty, the Yuan Dynasty ruled China for 89 years, and after the Ming Dynasty, the Qing Dynasty ruled China for 265 years. After 1840, the challenges faced by the Chinese nation (including Mongolia and Manchuria) became worldwide. 5. Homogeneity of dynasty politics. Judging from the basic or leading factors of the demise of the dynasty, it is nothing more than tyranny, ignorance and bad politics. When Wang Chaogang was founded, except for a few, most of them had a period of development and prosperity, and then they entered a period of decline, that is, the stage of tyranny, ignorance and bad government, and finally they perished. The ruling group of the developing dynasty was politically sober, but it was carried away in its heyday, and it was even more ridiculous and stupid in its decline. The so-called Lord of ZTE is just a flash in the pan. This is the same as the demise of the dynasty. What makes us sad is that the prosperous Song Dynasty was really destroyed by backward nomadic people. It seems that falling behind may not be beaten, but sometimes you can beat others. The key is the system. 6. Evaluation of dynasties. Because there are too few historical materials in Xia, Shang and Zhou dynasties, I dare not comment on them, but only evaluate the major dynasties after Qin dynasty from my personal standpoint. Wei and Jin Dynasties are the most popular places to speak. In addition, the most fashionable thing in those days was that men lost weight, and men even cared about their looks to the point of disgusting people today. It is the most beautiful time for men. The most powerful is the Tang Dynasty, so I won't go into details, because there are too many praises. I just want to emphasize that Tang poetry has influenced China's language. The most stupid people are the rulers of the Qing Dynasty and their clique. His folly is as follows: He took advantage of Li Zicheng to rebel and destroy Ming Dynasty, and gained the world conveniently, but he became a parasite. Raised the Eight Banners with the blood and sweat of the people of the whole country; If you don't make progress, there were western wind bands in Kangxi's palace, muskets used by the Qing army when they entered the customs, and there was no progress at all during the Opium War. I don't know how to absorb the essence of China culture to strengthen myself, but I try my best to extract its bones and muscles; At the end of the Qing Dynasty, the mansion was about to collapse, but it did not conform to the world trend of constitutional monarchy. Instead, it clung to the imperial zombies, hurting the Chinese nation, including Manchu, and causing a large number of Manchu compatriots to support their families after the Revolution of 1911.
