The second emperor of the Sui Dynasty was Yang Guang. Yang Guang was the second eldest, originally the crown prince was Yang Yong, but then the emperor changed Yang Guang, and many people believed that Yang Guang was good at using tactics, which was considered to have taken Yang Yong's crown princeship. There were also people who cried out for Yang Guang, but no matter what, Yang Guang became emperor.
However, the position of Emperor of the Sui Dynasty was not so easy to do, and in just a dozen years, he caused chaos in the world. Eighteen anti-kings, sixty-four smoke and dust came out.
Some people say that he is arrogant and lascivious, he is violent, he kills his brother and destroys his father, and he is absurd and unscrupulous... He did everything he could do. So what did Yang Guang, the Emperor of the Sui Dynasty, do to cause all over the place to rise up?
The construction of the Grand Canal, which is a place criticized by many people, when the Sui Dynasty Emperor built the Grand Canal, he over-requisitioned the people's power. Even women have to contribute, and heavy servitude has brought great disasters to the people. After the completion of the Grand Canal, it played a key role in strengthening the north-south connection, but it also provided convenience for him to feast and enjoy himself on the upper reaches of the canal.
Built the eastern capital and moved the capital to Luoyang. Moving the capital, the ancient capital is not like now, even now it is a very huge project, not to mention the ancient capital relocation.
Yang Su was the leader of the Luoyang Dongdu Project and was responsible for the construction, but the construction was piled up with people. In addition, he also overhauled the palace annexes in various places. Speaking of enjoyment, I'm afraid there is really no one else to compare.
You must know that in these projects, the large ones must serve one or two million people all year round, and the small ones must also requisition two or three hundred thousand people. These projects could not be completed in a short time and a half, and in that year, the people were not allowed to cultivate the land, but also carried out the project, which not only caused a large number of deaths of servicemen, but also seriously damaged agricultural production.
The Three Marches of Goguryeo, strictly speaking, this can not be said to be wrong. The people of Goguryeo had to bite the Central Plains Dynasty from time to time, and when they were weak, they were very honest, so in order to solve this hidden danger, the Sui Emperor marched on Goguryeo three times, but all of them ended in failure.
The above points, if viewed separately, are not the reasons for the demise of the Sui Dynasty, but are beneficial to the Sui Dynasty from a certain angle. For example, moving the capital, he is not the first in history, Zhu Di has also moved the capital, and the amount of engineering is also quite large. Speaking of the Grand Canal, other times do not say, his father Sui Wendi also did it. Not to mention the war, almost every dynasty had a war, and Goguryeo, which the Sui Emperor did not get, was also a serious problem for the Tang Dynasty, so the early Tang Dynasty also repeatedly conquered Goguryeo.
However, all of this is put on one person, and I am afraid that is the core of the problem. In just over ten years of work, such a long period of labor, military service, so that the people do not have a good life.
Of course, this is actually one of the reasons, the foundation of the Sui Dynasty itself is unstable, and the internal contradictions are very prominent, but under the premise that these are not resolved, the Sui Emperor began a large-scale conquest, which is the root cause of various contradictions.
