During the Three Kingdoms period, why did the northern tribes dare not go south, and what was the fu

Although some of the northern nomads were more brave and warlike, they were few in number, and it took some time to recover from each war. For these reasons, they did not dare to rush south, and still chose to occupy their own land as kings.

Although the Three Kingdoms period was chaotic, almost every force suppressed the northern tribes within its own range, and if they went south, they were more likely to be attacked by the heroes. Although the Western Jin Dynasty was unified, its military strength was not strong. And some nomads have developed and become more powerful, so they dare to go south.

Because there are no conditions to go south, because the northern nomads need time to recover from every war, so they dare not rush south.

During the period of the Three Kingdoms, they occupied the mountains as kings, and their own internal wars could not be solved, and it was unrealistic to go south to war, because of the war, the Hu people would not come over, the Western Jin Dynasty was not voluntary, and the Western Jin Dynasty consumed a lot, and introduced the Hu people into the Central Plains, and finally took refuge in the south under the group beating of the northern nomads.

Because of the political situation at that time, the current result was that after the war, it was necessary to recuperate.

Because the development of the northern tribes during the Three Kingdoms period was relatively backward, there was no strong force, and it was impossible to defeat the powerful forces of the princes.

Because there is no condition to go south, the northern tribes already have a lot of things to do on their own, how can they have the energy to go south to expand their territory?

I think the main reason is that they don't feel that they are strong enough, and there is also the result that their rulers are not so conscious.

The three kingdoms of Wei, Shu and Wu were strong, and the northern nomads were not opponents, so they did not dare to take the opportunity to enter the Central Plains.

Because Cao Wei did not relax his defense against foreign tribes during the Three Kingdoms period, Cao Cao arranged for Cao Zhang to guard the frontier.

In fact, the northern ethnic groups are also very powerful, but at that time, during the Spring and Autumn Period and the Three Kingdoms, the reason why the Central Plains did not dare to go south was mainly because they were afraid that they would also be threatenedBecause if they go south at that time, it is easy to produce their joint attack, and then lead to themselves in the mouth of the wolf, and in the end, not only will they not gain anything, but they may also put themselves in

In fact, during the Spring and Autumn Period and the Warring States Period, the Xiongnu did not want to invade the Central Plains, butEvery time he attacked, he was completely suppressed by the Central Plains, without the ability to continue south. Moreover, the nomads are suitable for living on the grassland, even if they go south, they can't live for a long time, so they will only plunder some resources, so they will not choose to suffer a lot of damage, and in the end, many countries in the Central Plains will hurt him, so that he has no room for survival.

In other words, in factThe north will not easily invade the south, because they are nomadic people and are not good at farming, and the Central Plains people will not easily attack the north, because the north is just a grassland, and even if it is defeated, it has no use value, so it is also relatively peaceful, the Xiongnu will only invade the Central Plains when there are fewer resources, and the countries of the Central Plains will only have their own wars, rather than considering the wasteland in the north, and put more of their focus on ruling the Central Plains.

Even in the case of chaos at that time, the nomads in the north had no interests to say if they invaded the Central Plains, and even if they won the battle in the end, they would return to the north, and the resources of the Central Plains in the war must be relatively small, so in the end there would not be much interest at all.

In order to weaken the power of the Xiongnu, Cao Cao put the Southern Xiongnu under house arrest in Yecheng, and also divided the Southern Xiongnu into 5 parts, resulting in the existence of the Southern Xiongnu in name only.

Although there was great internal chaos in the Central Plains at that time, if there was foreign incursion, it would still be unified to resist the war with foreign countries, so the northern ethnic groups did not dare to invade at will.

Because the warlords in various places at that time had very large military forces, they were not only fighting for territory with their own people, but also to prevent the invasion of the Xiongnu.

Because although the Central Plains was in turmoil at that time, if there was an invasion from other places, they were still unanimous to the outside world.

Because it is also necessary to understand the national strength of the Central Plains, the geographical location and form, and then comprehensively estimate whether their national strength can succeed in going south, so they did not go south easily.

I think this is because although the Central Plains was very chaotic at that time, the warlords were all unanimous with the outside world, so foreign tribes did not dare to invade.

Because although the Central Plains was very chaotic at that time, they would still unanimously deal with foreign invasions, so the northern ethnic groups did not dare to invade without authorization, so they did not dare to go south.

If there is an invasion from the outside, it will definitely be unanimous with the outside world first. Therefore, the northern peoples did not dare to go south easily.

That's because the Central Plains was particularly strong at that time, and when foreign invasions were incurred, they would definitely be killed together.

At that time, the northern nomads had not yet developed, and the Central Plains did not engage in large-scale commodity simplicity with them. The Central Plains seemed strong and prosperous to them, and they did not yet have the ambition to annex the Central Plains.

It is indeed because of Cao Cao, because of Cao Cao, the foreign tribes in the north are afraid of Cao Cao's prestige and dare not attack easily.

There was no war on the northern border in the Three Kingdoms era, not because of Cao Cao's relationship, the main reason was that the foreign nationality and technology were quite backward, the Central Plains ethnic unity was united in the psychology of the outside world, the foreign forces were weak, and there were many contradictions within the ethnic minorities.

The most important thing is that the south has always been underpopulated.

From the birth of Chinese civilization to the Western Jin Dynasty, the civilization activities were in the north, and the main territory of the Southern Barbarian Chu State of the Zhou Dynasty was in Henan, and the farthest was Hubei, and Hunan was a place outside the country. During the Three Kingdoms era, no one paid attention to the south, and the big families were reluctant to go, and Jiangnan was mostly a lot of landlord forces who controlled large tracts of land, and the imperial power was useless here. When Sun Jian's father and son opened up the south of the Yangtze River, they only fought tens of millions of people, and at this time the north was more than 100,000 people.

It was not until the Eastern Jin Dynasty that the emperor fled south, and then he took many nobles from the north to the south, bringing with him the civilization system and science and technology, and the south began to develop from then on.

I guess it's an ethnic minority.
