The war between Liu Che and Xiongnu in the early Han Dynasty consolidated the new regime.

Maintaining national unity is an act of "making contributions to the present and benefiting the future"

The battle between Emperor Wu of the Han Dynasty and Xiongnu was a very influential event in the Western Han Dynasty. Liu Che, Emperor Wu of the Han Dynasty, was an outstanding politician in the history of China. Successfully resisted the invasion of Xiongnu slave owners and nobles, and further consolidated the emerging feudal regime in the early Han Dynasty.

Xiongnu is an ancient nomadic people in northern China. The slave country was established in the early Han Dynasty, and the country became strong. In the east, they defeated the East Lake, in the west, they drove away the Da Yue family who lived in present-day Gansu Province, and in the north, they surrendered to the Dingling family. In the south, they often invaded the border of the Han dynasty, sometimes as far as 350 kilometers from the capital of the Han dynasty, which seriously threatened the feudal regime of the Han dynasty.

In 200 BC, Emperor Liu Bang led 320,000 troops to fight against the Huns, but was besieged by 400,000 troops of the Huns in Deng Bai for 7 days and 7 nights. Since then, in order to fully deal with the internal feudal separatist forces, Liu Bang temporarily adopted the policy of "reconciliation" with the Xiongnu. Marry the maid-in-waiting to the Xiongnu leader and send a certain amount of gold, silk, wadding rice and wine every year for the people to trade. After several generations of emperors, although they once paid attention to reforming the border defense system and reclaiming wasteland, they failed to completely solve this problem.

In BC 14 1 year, Emperor Wu of the Han Dynasty 16 years old ascended the throne. At this time, the Han dynasty has been established for more than 60 years, the feudal regime has been consolidated, and the economy has also gained strength. Therefore, he has the conditions to confront the Huns and fundamentally remove the threat from the mainland. In BC 133, Emperor Wu of the Han Dynasty called his ministers to discuss the policy towards Xiongnu. Wang Hui, the hawk, said, "I heard that Daiguo in the Warring States period was a small country that could fight against Xiongnu. Now your majesty is strong and the country is unified, but the Huns invaded the thieves not only because they were not afraid of us. I think it's better to beat the Huns. " Han Anguo, the censor, repeatedly objected. He said: "Gaudi was besieged when he defeated the Huns. He didn't eat for seven days, so he had to make peace. So far, he has been safe for five generations.

It's best not to call. "Wang Huiyan refuted Han Anguo's argument, and suggested that the front should go deep and adopt the method of" ambush ". Emperor Wu of Han supported Wang Hui in the war of resistance. The Hungarian-Chinese war began. From 133 BC to 1 19 BC, Emperor Wu of the Han Dynasty sent troops to fight against the Huns many times. There are three decisive battles: the battle of Henan, the battle of Hexi and the battle of Mobei.

In BC 127, Xiongnu nobles invaded Shanggu and Yuyang with 20,000 cavalry. Emperor Wu of the Han Dynasty sent Wei Qing, a general of the Qing Dynasty, to ride out the cloud at a rate of 30,000, heading for Longxi, recovering the Hetao area and sweeping away the military strongholds invaded by Xiongnu. Wei Qing took a circuitous attack and outflanked from the rear, driving away the Loufan King and the Aries King of Xiongnu in one fell swoop, thus removing the threat of Chang 'an.

So Emperor Wu of the Han Dynasty set up Shuofang County and Wuyuan County there, and 100,000 immigrants reclaimed land, rebuilt the old Great Wall of Qin Dynasty and sent troops to station there. Wei Qing was promoted to Changping Hou. In 124 BC, Wei Qing led cavalry to drive away Xiongnu right Wang Xian, captured Xiongnu slaves 10 and returned home in triumph. Emperor Wu of the Han Dynasty promoted Wei Qing as a general and became the commander-in-chief of the whole army. In the second year, in the battle with the Huns, a general Huo Qubing, aged 18, appeared. He is Wei Qing's nephew. Once, he took the lead and led 800 cavalry into the Xiongnu camp for hundreds of miles, winning a great victory. On this basis, Emperor Wu of the Han Dynasty appointed him as the Crown Prince and built a splendid house for him to see. Huo Qubing said: "The Huns are still alive and have no home!" Show strong patriotic enthusiasm.

The battle of Hexi began in March 12 1 BC. Huo Qubing set out from Longxi with ten thousand cavalry.

The Mobei campaign was the largest in BC 1 19. Emperor Wu of the Han Dynasty sent Wei Qing and Huo Qubing with hundreds of cavalry and hundreds of thousands of soldiers to attack Huns Khan in Mobei from Dingxiang County and Daixian County respectively. Wei Qing crossed the desert for more than 1000 miles and reached Yutian Mountain, killing more than 19,000 enemy troops. Huo Qubing went deep into 1000 km, pursued Xiongnu Zuo Wang Xianbing to Xushan, and captured more than 74,000 enemies. In this battle, Emperor Wu of the Han Dynasty also organized140,000 soldiers and horses to accompany him, and sent10,000 trench troops to transport grain and grass, thus ensuring the supply of main materials.

The Battle of Mobei dealt a fatal blow to Xiongnu, resulting in the situation that "Xiongnu is far away and Mobei has no Wang Ting". Since then, the Huns have migrated northward to Mobei. From the northern part of the Han Dynasty to Lingzhou in the west, 600,000 officials settled fields and strengthened their defense. Emperor Wu of the Han Dynasty won the war against Xiongnu, which made the country more unified. Inside and outside the Great Wall, "cattle and horses indulge and livestock are wild", which has created extremely favorable conditions for the development of economy and culture.
