In ancient times, the Sui Dynasty reached a unified dynasty, but what we think of most is the Tang Dynasty. After all, Li Shimin in the Tang Dynasty was really famous. Since the Tang Dynasty took Chang 'an as its capital, it directly reached a world-class level. But few people know that the strength of the Sui Dynasty is not much weaker than that of the Tang Dynasty, but the powerful Sui Dynasty disappeared in the long river of history like a flash in the pan. So what's wrong with the Sui Dynasty? The reasons for the demise of the Sui Dynasty are as follows: 1. The Sui Dynasty was formally established in 58 1 year of Emperor Wendi. From this day on, the whole world was unified in the shortest time, ending the division of the Northern and Southern Dynasties at that time. After reunification, the Sui Dynasty made great achievements in culture, politics, economy and diplomacy, and once became a world-class power. It can be said that this is the first time that all ethnic groups have come to North Korea. The word "prosperity will decline" may be a true portrayal of the Sui Dynasty. Reunification of China in the shortest possible time may give the Sui Dynasty an illusion that the whole world has no rivals, especially after Yang Di ascended the throne. However, the emperor's position was wrong, so since he ascended the throne, Yang Guang began his own way of death to show that he was more suitable to be the emperor of the Sui Dynasty than his father, Emperor Wendi. At that time, although the Sui Dynasty unified China in the fastest time, people all over the world didn't know how much they were hurt when they were in China. Although the people in the world entered the unified Sui Dynasty, their lives have not yet come out of hunger and cold. At that time, the five lakes slaughtered almost all the people in the Central Plains, and the entire Han people were almost extinct at that time, while the Sui Dynasty was just established for decades and never recovered. After all, it takes time. However, at that time, in order to prove that Yang Di was more suitable to be the monarch of the Sui Dynasty than Emperor Wendi, he decisively fought for Koguryo and personally conquered Tuguhun. To tell the truth, the ratio of male to female in the whole world at that time had reached a terrible level, that is to say, there were many boys and girls, which was a terrible thing in ancient times. After all, ancient men were the main labor force. At this time, what people in the world need most is to cultivate their life and improve their interest, but in order to prove their greatness, Emperor Yang Di once again put forward such a huge project as building the Grand Canal. Although it sounds like the Grand Canal Project belongs to China's top projects in the world, and it has benefited countless people, contemporary people suffer greatly. Many times, when the leader says a word, the subordinates run off their legs. Perhaps at that time, Emperor Yang Di didn't think that people's life had reached such a difficult point. He just looked at this huge benefit with his own eyes and never thought how much labor would be lost in this project. After all, even with our modern high-tech, there will be many casualties in building such a big project, not to mention the ancient project that was carried out entirely by manpower. No matter when, the only idea of people in the world is to live. If you can't even provide basic living security, these suffering people may have no way out anyway. It is better to rebel against the Sui Dynasty, and perhaps find a way out. It can be said that there are countless people's blood and tears behind everything, whether it is personally conquering Tuyuhun, conquering Koguryo, or building the Grand Canal, not to mention building Luoyang, the capital of the East. Second, the contradiction between the north and the south at that time, after being unified by the Sui Dynasty, seemed to belong to the Sui Dynasty on the surface, but we should know that the south at that time belonged to the conquered, and the conqueror and the conquered were never equal. After all, countless soldiers were lost in the whole war at that time, and these hatred did not pass through the transition of one or two generations, and it was impossible for the people at that time to live together well. The main force of the Sui Dynasty was the north. Similarly, when the north ruled the south as a winner, the means used were more high pressure. Sui dynasty can unify the world in the shortest time. It is obviously impossible to say that it has not used a high-handed policy. It is for this reason that various contradictions among the people began to be provoked. I remember playing a game before, Xuanyuanjian, which was actually about the revenge experience of the Chen Dynasty after it was destroyed by the Sui Dynasty. To tell the truth, the monarch of the Chen dynasty has long lost the heart of revenge. He just wants to live in peace, but his master and the old minister of the Chen dynasty are trying to find ways to avenge the Chen dynasty. Why do you think so? To put it bluntly, it is caused by the unequal treatment between northerners and southerners. It can be said that the whole people in the south can't survive under this high-handed policy, so a large number of anti-Sui forces have emerged in various places. In order to speed up the construction of various facilities throughout the Sui Dynasty, Yang Di can only consider the policies of the whole country, such as increasing taxes, and the main way to increase taxes is to conduct a census of population movements. After all, the people at that time paid taxes according to their heads. You know, after the establishment of the Tang Dynasty, the population of the whole country was only10 million, and when it followed North Korea, the population had reached about 40 million, only eight years later. Can it be said that the construction of the Grand Canal in the Sui Dynasty directly killed or injured 30 million people? This is not120,000 population, but 30 million population. If there is nothing strange, you may not believe it. To tell the truth, every dynasty has a very detailed investigation of the number of people. After all, this is related to the overall tax revenue of the country. Then the Sui Dynasty, which entered the DPRK, can get the data of 40 million people, either this data is false or the Tang Dynasty faked it. Then the question is, who is more beneficial to this kind of fraud? At that time, in order to speed up the progress of the project, Emperor Yang Di began to complete the task under the etiquette of North Korea, which was controlled by bureaucrats at the lower level. After all, Emperor Yang Di has always belonged to a very strong emperor, so his orders only need the following officials to do for him, and it is not his responsibility as to how to finish them. Emperor Yang Di only wanted this result. So the following families or management began to make all kinds of fakes. At this moment, the population began to expand, reaching 40 million people in an instant. But in fact, there is no such exaggerated data, but these people directly sent these data to Yang Di in order to cater to Yang Di's favor. When Emperor Yang Di got this data, he directly thought that the Sui Dynasty still had great potential to be tapped, and then the world collected taxes according to the population of 40 million. However, there were not such a large number of people at that time, and these aristocratic families who managed the people were helpless and could only squeeze the people harder. After all, at this point, if they don't take food from the people, they have to pay for it themselves. So countless people were forced to rebel. After all, people all over the world have to pay four times their own taxes. Even if they hand over all the food at home, they still can't reach the basic level of taxation. Is there any other way out of rebellion at this time? It can be said that Emperor Yang Di was deceived by this false data, but the reason for all this lies in Emperor Yang Di himself. Without his lofty aspirations, there would be no such false data and no displacement of people all over the world. Fourth, the final counterattack of aristocratic families Although the Sui Dynasty finally unified China, part of the country was still in power by aristocratic families and nobles in the Han Dynasty. In order to solve this problem, the Sui Dynasty began to improve the so-called imperial examination system. For a long time, the courtiers of the whole dynasty were recommended by aristocratic families and gentry, but now Emperor Yang Di has actually started to select talents from the people, which is almost equivalent to breaking the foundation of gentry, so that the gentry of the whole world will fall down because of the slow increase of the children of the poor. You should know that aristocratic families and nobles at that time have always been the most powerful level in the whole world except imperial power. Now Emperor Yang Di directly cut off the future of aristocratic families and nobles by using the imperial examination system, which is equivalent to enjoying all kinds of senior privileges all the time, and suddenly one day this privilege began to be cancelled. This makes aristocratic families unable to bear such a gap. It can be said that at this moment, the whole aristocratic family stood on the opposite side of the Sui Dynasty. In fact, this is the contradiction between imperial power and gentry. Emperor Yang Di was an impatient man. If this matter takes its time, there may be many opportunities. For example, the imperial examination system was also popularized in the later Tang Dynasty, but it took several generations of efforts to achieve it. It is also for this reason that the various forces of the cremation began to make a final counterattack against Emperor Yang Di. At that time, Yu Wenhuaji, Sima Deqi and Pei Gantong were actually representatives of the cremation, so a mutiny occurred in 6 18, and the emperor Yang Di was directly killed. Although Yang Dong, his second grandson, was appointed as the new emperor, Wang still didn't trust him, and eventually the whole Sui Dynasty was destroyed within two months. To sum up, the Sui Dynasty, as a unified dynasty, was doomed for the above reasons. It can only be said that Yang Guang is in a hurry, and many things will take several generations to complete. However, in order to prove his strength, Yang Di directly shortened the whole thing to several decades, so that the flourishing Sui Dynasty was directly eliminated in the long river of history.
