[The last few chapters introduce a lot of historical content, and this chapter will be given to you for free]

In the plot of these 1200 chapters, in addition to the various anti-kings in the last years of the Sui Dynasty, the Sui Dynasty itself actually occupies the most plot.

As the only two great unified dynasties in history that died in the second generation, compared with the Qin Dynasty, the fall of the Sui Dynasty is actually the most worthy of description and regret.

The reason for the fall of the Qin Dynasty is more actually the Mandate of Heaven, although the operation of Qin II Hu Hai is very abstract, but you only need to carefully study the history and you will find that the abstract operation of poisoning is limited to the palace of his own family, at most it is just asking the world to offer beautiful women and treasures. This is a very normal imperial operation in all dynasties, the Qing Dynasty emperor has to draft the world almost every year, why don't you see the Qing Dynasty II die?

In the first few years of Hu Hai's reign, almost the whole world was reversed, and even if he wanted to give any orders that would bring disaster to the country and the people, he couldn't convey it. Therefore, the Qin Dynasty did not perish in the hands of Hu Hai at all, and it had little to do with Qin Shi Huang. In fact, when the Qin Dynasty decided to implement the rule of legalism, implement the Shang Dynasty reform, and use the people as tools to fool and use, the Qin Dynasty was half dead.

If Qin Shi Huang is replaced by Emperor Wen of Han, then it may be able to be connected, but the first emperor is the first emperor, so the demise of the Qin Dynasty was already doomed when he ruled the world.

But the fall of the Sui Dynasty is different, the fall of the Sui Dynasty is really his own death, and it has nothing to do with the ancestors of the Sui Dynasty, after all, Emperor Yang of the Sui Dynasty is a simple old peasant for five generations, and there is no ancestral problem to toss his own descendants.

At the beginning of the establishment of the Sui Dynasty, the population was small, and the land contradiction was not intense. Although the family gate valve has been extremely strong, Yang Jian's means in the world are very powerful, and he has packed up the gate valves properly, so to be honest, it is really not difficult for the Sui Dynasty to be passed on for more than a hundred years.

It's a pity that there is such a talent as Yang Guang in the old Yang family, and he directly tossed his own national fortune.

In fact, at the beginning of Yang Guang's accession to the throne, although the court and the people already had the saying that Yang Guang killed his brother and father and usurped the throne, Li Er killed his eldest brother openly, and his father was closed.

But Yang Guang has a problem, that is, he is too smart, too decisive, too wise and martial, and one is too impatient.

Yang Guang was smart, so he saw through at a glance that there were two biggest problems in the future of the Sui Dynasty, one is that the pimple of Chang'an is no longer than that of the Han Dynasty, it is the fertile soil of Guanzhong with 800 miles of fertile fields and Pingchuan, but the place where soil erosion is serious, the population is too explosive, and food is heavily dependent on external input.

No matter how advantageous the geographical location of such a place is, if you can't feed people, you are mortal enemies, and your descendants stay in Chang'an, and it will be over sooner or later.

There are two ways to solve the problem, one is to solve it through transportation, build a highway, so that the grain in the south can be quickly imported to Chang'an, so that Chang'an will not be short of grain, and the ancient highway refers to the canal, before the emergence of cement, a ton of grain was transported by land, and the people who were responsible for escorting the road had to eat seventy percent, or even more.

It's better to have a canal, and the capacity of the ships can solve all problems.

The second way is to move the capital, find a convenient transportation and strategic location to use as the new capital.

Both approaches have their advantages and disadvantages, the former is a one-and-done solution, but it is costly. The latter is easy to execute, but the basic plate of the Sui Dynasty is the Guanlong aristocracy, and people will never accept you to move the capital to other places, and the political risk is huge.

Politicians with normal thinking generally start to do multiple-choice questions at this time, choose 1 out of 2, choose the least risky and easiest way to implement.

And the point of Emperor Yang of Sui is that he chooses children to do multiple-choice questions, and I want them all.

Therefore, Emperor Yang of the Sui Dynasty used a large amount of civilian power to build the Beijing-Hangzhou Grand Canal, and built it in the north and south directions at the same time, mobilizing hundreds of thousands of conscripts, and almost directly collapsed the economy of the north and south regions.

However, it should be clarified here that Emperor Yang of the Sui Dynasty did not really start from scratch and build a new canal thousands of kilometers long from scratch, but sent people to connect the existing sections of rivers and canals, and finally formed the Beijing-Hangzhou Grand Canal, so it is not so terrifying in terms of construction difficulty and mobilized people's strength, and it will not really cause a rebellion in the world, otherwise it would not be possible to build it in just a few years.

But it did deplete the economy of the North and the South greatly, and planted the seeds of hatred in the hearts of the common people.

On the other side, Emperor Yang of Sui wanted to build the eastern capital Luoyang, and he also wanted to build a capital in the south, and his old man ran back and forth with three capitals a year. Emperor Yang of the Sui Dynasty ran three times a year, and the court officials also had to run with him, and at the same time he had to run with the most elite army of the Sui Dynasty, and tens of thousands of people were constantly running around in three places across the country.

And the most important thing is that this will greatly reduce the influence of the Guanlong nobles. The Sui Dynasty was established with the support of the Guanlong aristocratic group, and if the national capital was stable in Chang'an for a long time, the Guanlong aristocratic group that was close to the water and the building was the first to get the moon would naturally obtain the rights of the central court.

But if the imperial court runs to three places in the north, south and central a year, the nobles of the three regions have the opportunity to get close to the central court and can obtain power more equally, which is naturally a good thing for the rule of the Sui Dynasty, but for the nobles of Guanlong, it will be a personal life.

Originally, the implementation of any of these plans had to be carefully considered, and even took more than ten years of hard work to slowly advance. But smart and decisive, the wise and martial Emperor Yang of Sui directly decided to implement it at the same time, and also offended the common people in the north and south and the nobles of Guanlong in one go.

In the first year of the Great Cause, Yang Guang decided to move the capital to Luoyang, and the fourth year of the Great Cause began, and the aforementioned 72 Road smoke and dust began to rebel one after another, and the early rebellions were concentrated in the northern region, under Yang Guang's nose.

The smart and decisive, wise and martial Yang Guang reacted immediately, behind this rebellion was actually the black hand of the Guanlong aristocratic group, they were dissatisfied with their plan to move the political center to Luoyang, resulting in their loss of power, so they planned to use the rebellion in various northern regions as a threat to force themselves to move the political center back to Chang'an.

Yang Guang was furious, how could a person like him be persecuted by other forces, and at this time, Goguryeo in the north was jumping around again, so Yang Guang had a genius idea, that is, to take the northern army with great influence of the Guanlong nobles to go on an expedition to Goguryeo, so that he could not only eliminate such a flea as Goguryeo, but also take advantage of the bad climatic conditions of Goguryeo to kill a large number of troops in the hands of the Guanlong nobles.

The Guanlong nobles have no army in their hands, so they will naturally let themselves rub it.

So Yang Guang announced that he was going to expedition to Goguryeo from the 8th year of the Great Cause, but unfortunately Yang Guang's idea was very beautiful, but the reality was very cruel, the invincible Yang Guang's first expedition was defeated, so he naturally had to fight the second time, but the second time he was defeated, and the angry Yang Guang started the third time, and the result was naturally defeated.

When Yang Guang was preparing for the fourth expedition to Goguryeo, he was horrified to find that the most elite army in the entire north of the Sui Dynasty was almost completely exhausted, and millions of people died in the north on the three expeditions.

This is not the most terrifying, the most terrible thing is that he originally planned to consume the army of the Guanlong nobles, but the army of the Guanlong nobles did not seem to consume much, but the hearts of the entire Sui Dynasty were completely consumed.

Yang Guang, who originally wanted to calculate the Guanlong nobles, found that he was the one who was calculated in the end, so the Sui Dynasty died!

It can be said that as long as Yang Guang does not toss and is at ease as a peaceful emperor, then Yang Guang, who opened the Beijing-Hangzhou Grand Canal or moved the capital to Luoyang, can still get the title of the first emperor of the ages, but he was finally defeated and became one of the symbols of the tyrant through the ages.

And the entire Sui Dynasty, also in the struggle between the imperial court and the family gate valve came to an end, the fall of the Sui Dynasty can greatly reflect the various contradictions and disputes between the centralized government and the local gate valve forces, the content and stories that can be written in it are simply not too much, Liu Xu started from Yang Guang's accession to the throne, and wrote until the three expeditions to Goguryeo, the various political struggles and military struggles in it are five or six hundred chapters of the plot.

Liu Xu wrote that it is cool, but the water is also real water!
