What does the conquest of Liaodong have to do with the Sui Dynasty and the fall of the Ming Dynasty?

The war dealt a very serious blow to the economy, and both wars dragged down the economy of the Central Plains Dynasty to the greatest extent.

Let's talk about the fall of the Sui Dynasty First look at the reign of Emperor Yang of the Sui Dynasty for only a short period of 14 years, but what he did First build the capital Luoyang Dredging and excavating the Grand Canal The Great Wall was built in the east The Tuguhun in the west was conquered by the Khitan The Great Banquet of the Turks Expedition to seek the three expeditions to Goguryeo and the construction of a fleet of 10,000 ships Several times in the Jiangnan Jiangdu This is what he has done in 14 years Let's first see which ones are completely meaningless Personally, I think it is completely meaningless to go down to Jiangnan several times I think the rest is too big a step to the egg First of all, it is necessary to give affirmation to foreign wars to recover the homeland of the nation, but he is too anxious If he can take his time, it would be good It would be too anxious to build and move the capital Luoyang So if Emperor Yang of Sui put all these military functions step by step, then he is also a good emperor who competes with Emperor Wu of the Han Dynasty, but he inflicts all this on the people, and it will be miserable The sun does not set in the industrial society, and it takes a hundred years to become the sun does not set Helping North Korea fight the war In the end, there was no substantial benefit All the foundation of Zhang Juzheng's reform was used up The fall of the Ming Dynasty was a natural disaster and a man-made disaster The advent of the Xiaoice period of natural disasters Economic blows to agricultural countries Man-made disasters The struggle for the national capital of the Donglin Party Secondly, crowding out and cracking down on other factions In opposing the collection of mining taxes Demanding an increase in land taxes The peasant uprising in the northwest and the rebellion of wild boar skins in the northeast caused a two-front war Germany's defeat in the second world war also had this reason And political corruption These are the main reasons for the fall of the Ming Dynasty.

During the Sui Dynasty, Emperor Yang of the Sui Dynasty once organized more than one million troops and launched the Liaodong War three times. There is only one reason why we have to go to Liaodong repeatedly at any cost:In order to defeat Goguryeo, a powerful country in Liaodong at that time.

1. The rise of Goguryeo

During the Han Dynasty, Liaodong was under the jurisdiction of Xuanfu County, Lintun County, Lelang County and Zhenfan County of the Han Dynasty. In the early and middle of the Three Kingdoms, Liaodong became the hegemonic place of the great warlord Gongsun family. In 238 AD, Emperor Cao Rong of Wei Ming sent the Taiwei Sima Yi to attack Liaodong and level the power of the Gongsun family in one fell swoop.

However, Liaodong was far away from the core area of Wei rule, and Wei gradually became overwhelmed by it, resulting in the gradual rise of Goguryeo in Liaodong.

After the fall of the Western Jin Dynasty, the Central Plains fell into a period of nearly 300 years of secession and chaos: the Wei, Jin, Southern and Northern Dynasties, the world fell apart, and a unified and powerful Central Plains Dynasty was never established, resulting in Goguryeo opening up territory in Liaodong and becoming stronger and stronger. In 581 AD, the Sui Dynasty finally ended the chaotic situation and the Central Plains was reunited, and Goguryeo had become a powerful country with a territory of thousands of miles, a large population, and sufficient soldiers and food, posing a strong threat to the nascent Sui Dynasty.

2. Why did the Sui Dynasty march into Liaodong to attack Goguryeo

The first is that Goguryeo is adjacent to the mountains and rivers of the Sui Dynasty, and it is difficult for others to sleep soundly next to the couch, and the second point is more crucial: Goguryeo, like the Sui Dynasty, was founded on agriculture and had a strong demand and possessiveness for land. The Central Plains Dynasty has always faced the threat of foreign enemies from the north, but these foreign tribes are basically nomadic tribes, living in pursuit of water and grass, nothing more than plundering, fishing and leaving.

However, Goguryeo, like the Central Plains Dynasty, also used agriculture as a pillar industry, and in order to meet the needs of population growth and recuperation, they had a strong and urgent rigid demand for land. In other words, even if the Sui Dynasty did not fight them, sooner or later they would move south to attack the Sui Dynasty, and it was only a matter of time.

Although Emperor Yang of Sui was regarded as a tyrannical king by later generations, he kept a clear head in this matter and resolutely used troops against Liaodong, trying to eradicate Goguryeo in one fell swoop, re-incorporate Liaodong into the pocket of the Central Plains Dynasty, and open peace for all generations. Therefore, the Sui Dynasty will send troops to Liaodong again and again.

After the fall of the Sui Dynasty, the two generations of emperors Li Shimin of Tang Taizong and Li Zhi of Tang Gaozong successively launched the battle of Liaodong, which also proved from the side how wise Emperor Yang of Sui was in his original decision.

The Sui Dynasty wanted to recover Liaodong, mainly to unify the country. Because Liaodong was occupied by Goryeo during this period. And the king of Goryeo, who was originally a vassal king of the Sui Dynasty, was unwilling to obey the emperor of the Sui Dynasty. An independent regime has begun. For the unification of the Sui Dynasty, it was necessary to recover.

Because Liaodong at that time was China's territory, and the recovery of this was also to swear its own ability and sovereignty.

Because it is the hub of the Northeast, its strategic position is very important, and it is a place where soldiers must fight.

1. The throat of the mainland connecting the northeast. In the case of backward transportation conditions in ancient times, it took a lot of human, financial and material resources to project the political and military influence from the Central Plains to the Northeast, and the land of Liaodong happened to be a very convenient transportation route and mode.

2. Goryeo's aggressive ambitions. Goryeo has always had its eye on the Northeast region and has been constantly invading the Northeast with small-scale wars. So the Sui Dynasty sent a large army to the northeast and decided to make an expedition to Goryeo.

On the one hand, it may be due to a lack of material, and on the other hand, it may be caused by their lack of accurate ruling plan and army strategy, and in the end they still ended in failure.

This was because the national strength of the Ming Dynasty was declining at that time, so it failed to solve the problem of Liaodong. In the end, the battle was defeated.

The final outcome is also over, after all, the problem at that time can be said to be very serious, and it has not been properly solved, so in the end, it can only be the result of not letting Tanyan feast, after all, there is no way.

Because the strength of the Ming Dynasty was not as good as before and gradually declined, it was impossible to solve the problem of Liaodong, and the Qing Dynasty was also very restless at that time.

Because Shanhaiguan was the starting point on the east side of the Great Wall, and Wu Sangui, the chief soldier who guarded Shanhaiguan at the end of the Ming Dynasty, saw that the power of the Manchu Qing was getting stronger and stronger.

Later, they secretly defected to the Qing Dynasty, and later when the Qing army came, they personally led them into the pass, and the Great Wall was originally the last line of defense in the northeast, but now it is ineffective. In addition, at that time, Li Zicheng's peasant rebel army had captured Beijing, and as soon as they heard that the Qing army had entered the customs, they hurriedly retreated, and Beijing was empty and there was no army. Therefore, the Qing army easily took Beijing, and the next thing was to attack the south to unify the Central Plains, and the various Southern Ming regimes in the south were naturally vulnerable.

In addition, there were many Ming Dynasty ** rebelled under the coercion and temptation of the Qing **, so soon the Qing army took the south. At this time, Zheng Chenggong also recovered Taiwan and was stationed in Taiwan, and Kangxi later defeated Zheng Ming's regime, recovered Taiwan, and unified the whole country.
