Li Shimin said, If Gao Gooli is not removed, the future generations will be in great trouble. Wha

The above two, don't mislead others, Goguryeo and Goryeo are not a country, nor an era, Goryeo is the ancestor of the Korean people, and Goguryeo is not, don't confuse Goguryeo's surname is Goguryeo, and Goryeo's surname is Wang!

It is also better not to speak with racist views

The territory of Goguryeo is probably the area of Liaoning and Jilin in China, bordering Mahan, Muhan, Jinhan (Sanhan) and Fuyu (probably North Korea). This area is a multi-ethnic settlement, and it is also friendly with nomadic people such as Xianbei and Wuheng. The people's customs are fierce, which is really a harm to our country.

At that time, there was no Korean nation, and Emperor Yang of Sui and Emperor Taizong of Tang still regarded it as the inherent territory of their ancestors.

In Chinese history, the Sui and Tang dynasties fought against Goguryeo for half a century, and finally drove it out of the Liaodong region completely, which used a lot of manpower, material and financial resources, but several generations of emperors still did not hesitate to fight, which shows that the threat of Goguryeo is great, mainly reflected in several aspects.

In fact, most people have the misconception that Goguryeo is the same as the territory of today's Korea, but in fact it is not, their territory extends to most of today's northeast region, and occupies the Liaodong Peninsula, bordering the Tang Dynasty in the south, and the Turkic and Tatar in the west. By land, once Goguryeo sent troops from the north together with the Turks and Tatars, it was difficult for the Tang Dynasty to fight on multiple fronts. It is even easier to occupy the Liaodong Peninsula and invade by sea, the Liaodong Peninsula is like a sharp knife, the northern coastal areas and even the hinterland of the dynasty are exposed to it, and the geographical threat is very great.

Goguryeo is different from the Turkic and other nomadic peoples in the west, they are mainly planted, relying on the geographical advantages of the Northeast Plain to develop planting and animal husbandry, the economy is developed, and the country is relatively stable. Politically, it is to complete the initial construction of the first centralized system, the political system is relatively perfect, and it is a country comparable to the Tang Dynasty, similar to the "Little Tang Dynasty", once it grows, it is a great threat to the influence of the Tang Dynasty in neighboring countries.

In fact, the relationship between the early Tang Dynasty and Goguryeo was not bad, butGoguryeo repeatedly stirred up relations between the Tang Dynasty and other northern countries, disobeyed Tang Chaoyang, and even took in the soldiers of the Sui Dynasty. This was indeed intolerable in the eyes of the Tang Dynasty. In addition, due to the coup d'état in Goguryeo, the policy towards the Tang Dynasty gradually shifted from peace to aggression, and many attempts to annex Silla showed its wolf ambitions.

In 668, the Tang Dynasty occupied the entire Liaodong Peninsula and invaded Pyongyang, ending Goguryeo's glory and leaving no country to threaten the Central Plains.

Goguryeo is the Korean Peninsula, and Japan and the United States invaded China to occupy the Korean Peninsula first, so its strategic position is very important and should not be underestimated.

Although the history books do not record the cause of the conquest of Goguryeo, the main reason is that Goguryeo in the sixth and seventh centuries had developed into a powerful regional kingdom in East Asia, which posed the most direct and dangerous threat to the revival of China. Goguryeo in the sixth and seventh centuries was to the Sui and Tang dynasties, just as Carthage was to Rome in the first three centuries, and the Manchu Qing dynasty was to the Ming Dynasty in the seventeenth century.

Because Goryeo's strength was growing step by step and gradually threatening China's northeastern border, Tang Taizong said that if Goguryeo was not eliminated, it would be a great disaster for future generations.

Because different dynasties in our country have the trouble of foreign invasion, but the degree is different, Tang Taizong knew that Goguryeo would definitely threaten the Tang Dynasty if it was strong, so it must be nipped in the bud before they became strong.

The Goguryeo nation was very resilient, which made Emperor Wen of Sui restless, and finally the Sui Dynasty died and was inspired to destroy the country. Li Shimin very much agrees with Emperor Wen of Sui's view, and has been working hard for this goal all his life.

It means that Goguryeo influenced the northeastern border of China, and now the Tang Dynasty people are strong and strong, and they should take advantage of the situation to eliminate this border trouble, in case future generations are incapable of influencing the rule.

Goguryeo was undoubtedly a hungry wolf. Although it is no match for the tiger of the Central Plains regime on the frontal battlefield, it will always secretly take advantage of the tiger's inattention to pounce and bite it, although such encroachment seems insignificant in the short term, but the consequences can be imagined in the long run.

In fact, it was because Tang Taizong attacked Goguryeo many times at that time, but the results were all in vain, and the country was constantly expanding its strength, Tang Taizong was very worried.

Because the Goguryeo nation is more fierce and possessive, Tang Taizong was worried that this nation would be the enemy of the Tang Dynasty in the future, so he wanted to get rid of him.

Because Goguryeo's ambitions were too great, and it was connected with both Turkic and Tatar, it was a great threat to the northern border of the Tang Dynasty in the north.

Because Tang Taizong failed to attack Goguryeo many times at that time, he felt that this was a difficult bone to gnaw, so there were such statements and feelings.

Because Goguryeo was not a weak country, at its strongest it accounted for three-quarters of the present-day Korean Peninsula, most of the northeast, and part of present-day Russia.
