The Eastern Han Dynasty spent another two hundred years under the leadership of Liu Xiu, the Emperor of Han Guangwu. As the saying goes, the combination of long will be divided, the division of long time will be united, at the end of the Eastern Han Dynasty, the Han Dynasty encountered great trouble, the great outbreak of the Yellow Turban Rebellion shook the foundation of the Han Dynasty, and the states and counties in various places became princes who supported the army and respected themselves.
The capital was smoked by Dong Zhuo and his subordinates, the people of the capital were miserable, and tianzi's feet became a purgatory on earth. The states and counties everywhere are not happy, the princes fight each other, you beat me, I kill you, and the bitter people are still the common people. During the Eastern Han Dynasty, the population peaked at 50 to 60 million, and the population was less than 3 million until the time of Cao Cao's Battle of Chibi. The war depleted the popularity of the Central Plains, and even more made the Central Plains wither and lifeless.
The Chinese nation is the beginning of the Han nationality, with a long history, and after many times of reproduction and development, it has gradually formed a powerful nation. Occupying the fertile soil of the Central Plains for agricultural life, a comfortable and harmonious life makes many ethnic minorities envious, their hard nomadic life has also developed a fierce character, they have a strong combat strength, from the beginning of the emergence of Chinese civilization constantly harassed, intending to invade the territory of Our Chinese civilization, the Great Wall built by the first emperor Qin Shi Huang is used to resist the Xiongnu, and the princesses and relatives of the Han Dynasty are also to alleviate the invasion of foreign tribes.
So why did the Three Kingdoms in the chaotic world not invade the minorities, it turned out that Cao Cao, Liu Bei and Sun Quan all did these things. No wonder no ethnic minority dared to invade the Central Plains.
During the Three Kingdoms period, the leader of the Central Plains was the State of Wei, and the founder of the State of Wei was Cao Cao, when Cao Cao defeated Yuan Shao in the northern melee, unified the northern lands, and became the biggest speaker, he reused Tian Yu, who had been under the white horse general Gongsun Zhan, who had followed Gongsun Zhan from an early age to shock the northern ethnic minorities, and the white horse yicong made the northern ethnic minorities frightened. After following Cao Cao, Tian Yu's military ability continued to improve, and he was even more comfortable dealing with Wu Huan in the north, and Cao Cao not only let him guard the north, but also let his son Cao Zhang guard it together. Cao Zhang's bravery and Tian Yu's ability to invade northern Wuhuan had no possibility of invasion at all, and Cao Cao simultaneously issued the Tun Tian Order, allowing ethnic minorities to cultivate land, and where would the ethnic minorities who had land would think of war.
Liu Bei occupied Western Shu and became the overlord of the Kingdom of Tianfu. After plotting and then moving, he implemented step by step after the Longzhong pair of the three divisions of the world in Jingzhou, he subdued the Barbarians such as the Xiliang Ma Chaowei Zhenqiang Clan, Ma Chao He Xuren, the descendant of the Fubo General Ma Yuan, the martial arts were extraordinary, and they had long galloped in the land of The Western Liang, and were called the Heavenly God General by the Southern Barbarians, and he did not dare to invade the barbarians. Later, Meng was rebellious, and Zhuge Liang quickly quelled the barbarian rebellion, which shows that the Shu state will not let the ethnic minorities become bigger, and as soon as there is a rebellion and invasion, it will be destroyed immediately.
Sun Quan dominated Jiangdong and was also the latest to claim the title of emperor. Beginning with Sun Ce's era, Eastern Wu began to eliminate the Shanyue ethnic minorities in the Jiangdong area until Sun Quan was still in progress. They had the Yangtze River to defend Cao Cao's attack in the north, but they could not allow barbarian invasions in their rear, and once the mountains were more and more powerful, Eastern Wu would definitely select elite troops to destroy them. As a result, it was difficult for the Eastern Wu region to have ethnic minorities who could threaten Eastern Wu rule.
It is not difficult to see from the history of the three countries that the rulers of the three countries will do their best to curb the invasion of ethnic minorities and protect the stability of their lands. In fact, among the Three Kingdoms, only Wuhuan in the north was able to threaten the Central Plains, which suppressed the minority nationalities of the Xiongnu, but they encountered Cao Cao, a tyrant with wisdom and means, they had no chance to invade the Central Plains, and there was Cao Cao in the north who insisted, and naturally there would be no invasion of ethnic minorities during the Three Kingdoms period.
