At the beginning of the Han Dynasty, the recuperation under the rule of Huang Lao accumulated a huge amount of social wealth for the Han Dynasty, and the pacification of the Seven Kingdoms Rebellion further consolidated the centralization of power, and the Han Dynasty had the strength to fight against the Xiongnu Khanate economically and politically, but there was still a lack of a commander.
On the 17th day of the first month of 141 B.C., the sixteen-year-old Liu Che performed the crown salute, and ten days later Liu Qi, the Emperor of Han Jing, died of illness, and Liu Che succeeded to the throne of the Han Emperor, and a commander was born.
However, the Empress Dowager Dou Yifang is still there, the Empress Dowager Wang Wan is still there, and the foreign relatives led by the two empress dowagers have great influence in the court, and Liu Che must also "Qin Shidong Palace", that is, the major affairs in the court are still controlled by the queen mothers, and Liu Che cannot govern independently.
In 135 BC, Empress Dowager Dou died, and Liu Che began to govern independently, thus beginning the war against the Xiongnu.
There has been no major conflict between China and Hungary for a long time because of their affinity, but the humiliation inflicted by the Xiongnu on the Han Empire will not disappear because of this peace.
In 133 BC, an ambush began, luring the enemy into depth. The Han Empire sent the general Wang Hui to lead an army of 300,000 to ambush on both sides of the valley in Mayi (Shuozhou, Shanxi), and Nie Yi, a powerful man who had business dealings with the Xiongnu, told the Xiongnu spies with the heads of two death row prisoners that he had killed the administrator of Mayi and asked the Huns to take advantage of the situation to pursue them. The Xiongnu military minister Shan Yu believed it to be true, and sent 100,000 troops to enter from Wuzhou, that is, Zuoyun, Shanxi, and prepared to attack Mayi. However, when the military minister marched to 100 kilometers away from Mayi, he found that he saw only cattle and sheep and no shepherds, so he grabbed Youyu and inquired about it, and it turned out that the Han had 300,000 heavy soldiers in ambush in the valley ahead. The military ministers were ordered to retreat in a hurry, and the Chinese achieved nothing in this ambush.
However, this ambush completely broke the years of harmonious diplomatic relations between China and Hungary, and the Xiongnu Khanate began to resume its continuous aggression against China. But at this time, what the commander Liu Che wanted was an excuse to go to war. As a result, the Han Empire, under the southern invasion of the Huns, carried out a series of continuous attacks on the Huns.
In 129 BC, the soldiers of the Han Empire divided into four routes and attacked the Xiongnu. The general Wei Qing attacked from Huailai in Hebei, and the general Gongsun Ao from Daijun, the general Gongsun He from Yunzhong, and the general Li Guang from Yanmen jointly launched a fierce attack on the Xiongnu.
In 128 B.C., Wei Qing and Li Xi led the troops out of Yanmen and Dai County.
In 127 BC, the main force led by Wei Qing and Li Xi once again went out of the clouds and marched westward to attack the Xiongnu. This sortie was a major victory, the Xiongnu were defeated, and the Han Empire once again recovered the Heketao region and built Shuofang City between the Hetao and the Yellow River.
In 124 B.C., Wei Qing led six generals and soldiers to attack northward in three ways, this time penetrating 300 kilometers into the Xiongnu Khanate, capturing more than 10 Xiao Wang, 15,000 men and women, and nearly a million cattle and sheep.
In 123 BC, the Han Empire did not have any idea of stopping, and continued to attack from Dingxiang with six generals led by Wei Qing. However, the Han army was defeated, the 3,000-man cavalry regiment of the general Su Jian was annihilated, the general Zhao Xin's troops were defeated and surrendered, and the Huns built Zhao Xin City for Zhao Xin.
In 121 BC, only two years after the Han Empire suffered a setback, it continued to use troops, this time from Longxi by the young general Huo Quai. Huo Qubing led the cavalry to cross 500 kilometers of Yanzhi Mountain, killed 1,000 people below the famous king of the Huns, and won the victory. In the same year, Huo Qubing still attacked from Longxi, crossed the Juyan Sea and went deeper than 1,000 kilometers, killing more than 30,000 Huns.
Huo Qubing won two major victories in one year, especially the second victory, which completely lost the Hexi Corridor where the Xiongnu Hun evil king was stationed. The Xiongnu Shan Yu Yi Ya was furious and wanted to hold the Hun evil king responsible, and the Hun evil king was killed, and as a result, he surrendered to the Han Empire with his tribe and land, which was a major blow to the Xiongnu Khanate.
The ten-year war against the Xiongnu achieved a phased victory, and the Xiongnu also realized that their glory had passed, so they had to adopt the advice of the general Zhao Xin, and only went north of the Hanhai Desert and moved the entire national border north. But for the Han Empire, the decisive victory had not yet come, and it would not stop because the Huns retreated north, and the blow to the Xiongnu continued.
In 119 B.C., Wei Qing went out of Dingxiang, Huo Qu was sick out of Daijun, and launched a general attack on the Xiongnu. The Weiqing Legion penetrated more than 500 kilometers deep into the Xiongnu, and Yiya rushed to meet the battle, but was defeated and continued to flee north. Wei Qing pursued to Har and Lin Zhao Xincheng, but there were no Xiongnu relics. General Li Guang lost his way and committed suicide. Huo Quai's army went deep into the desert for more than 1,000 kilometers, crossed Lihou Mountain, crossed the Gonglu River, defeated the Xiongnu Zuoxian Wang, captured 83 people including Tuntou Wang and Han Wang, killed more than 70,000 Huns, pursued to Wolf Juxu Mountain and disappeared from the enemy, Huo Qubing held a sacrifice ceremony in Wolf Juxu Mountain, and held a sacrificial Zen ceremony in Guyan Mountain (now north of Kent Mountain in Mongolia), and the soldiers approached Beihai.
After the Battle of Mobei, there was no royal court in the south of the Hanhai Desert, and the existential threat of the Xiongnu Khanate to the Han Empire for many years was completely lifted. As a result of this battle, the Xiongnu lost control of the northeast region, and the Hexi Corridor was completely incorporated into the territory of the Han Dynasty, and four counties of Jiuquan, Wuwei, Zhangye, and Dunhuang were set up in Hexi.
In 117 BC, because the Xiongnu Shan Yu Yiya refused to submit to the Han, the commander Liu Che was ready to continue to attack the Xiongnu in the north, but the general Huo Qubing suddenly fell ill and died, leaving the Han without a genius general. After that, Emperor Wu of the Han Dynasty Liu Che did not attack Hu for a long time, and the Han Empire's offensive against the Xiongnu Khanate came to an end.
After the Battle of Mobei, the Xiongnu suffered heavy losses, but they still could not make it succumb, but they were also unable to move south. After more than 10 years of using troops, the Han Empire caused the people to be exhausted, and by 107 BC, there were more than 2 million displaced people in the eastern part of the country, and 400,000 people were not registered in the household registration. After more than ten years of recuperation and recuperation, the Xiongnu recovered their vitality and remained the fierce enemy of the Han Empire, and once again became the border trouble of the Han Empire.
In 101 BC, Emperor Wu of the Han Dynasty issued an edict to conquer the Xiongnu again. The Xiongnu's new Dan Yu and Marquis succeeded to the throne, and he expressed his willingness to reconcile the two countries and return all the Han envoys detained in the past to Chang'an. Emperor Wu of the Han Dynasty agreed to a settlement, Sino-Hungarian diplomatic relations were restored, and in 100 BC, Su Wu was sent as the main envoy and Zhang Sheng as the deputy envoy to the Xiongnu. However, the patriotic Zhang Sheng conspired with the Han people who had surrendered to the Xiongnu to kill Shan Yu's minister Wei Lu and kidnap Shan Yu's mother to return to Han when he was out. As a result, the conspiracy was revealed, and after a killing, the patriotic Zhang Sheng showed opportunism and turned to surrender to the Xiongnu, while the unsuspecting Su Wu refused to surrender, and the Huns exiled him to Beihai. The newly restored diplomatic relations between the two countries were destroyed by Zhang Sheng, and the war resumed.
In 99 BC, the Han army attacked the Xiongnu in two ways, one led by the general Li Guangli, sent troops to Jiuquan, penetrated deep into the Western Regions, and was defeated by the Xiongnu. One route was Li Ling, that is, the grandson of the old general Li Guang led 5,000 infantry to Juyanhai and attacked the Xiongnu to the north. Encountering the 30,000 people led by Marquis Shan Yu, Li Ling killed thousands of people, and had to retreat. In the retreat, Li Ling set fire to save himself, set up an ambush to meet the enemy, and killed 3,000 Huns, and the Huns still could not win after more than ten days. In the end, Li Ling was surrounded by the Huns and led the army to break through, and another general, Han Yannian, was killed by an arrow, and Li Ling was captured.
In 97 BC, the Han Empire sent Li Guangli, Han Shuo, and Gongsun Ao to attack the Xiongnu with three armies of Shuofang, Wuyuan, and Yanmen respectively. The Xiongnu retreated north.
In 90 BC, Li Guangli went out of Wuyuan to attack the Xiongnu in the north. However, Emperor Wu of the Han Dynasty arrested Li Guangli's family on charges, and Li Guangli, who was pursuing, heard the news and surrendered to the Xiongnu, and the military action against the Xiongnu was again frustrated.
Faced with the constant pursuit of the Han Empire, the Huns tried their best to avoid fighting the Han army. However, the continuous wars also made the Han Empire tired, and the Han and Hungarians maintained a stalemate between the wars and the times.
In 87 BC, Liu Che, the great commander of the Han Empire, died.
Liu Che reigned for 54 years, and the war against the Xiongnu lasted from his reign until his death. The decades of war against the Huns not only relieved the Xiongnu, the biggest border trouble, but also allowed China to recover the Hetao region, incorporate the Hexi Corridor into China's territory, and open up the Silk Road, bringing the Northeast and Western Regions into the jurisdiction of the Han Dynasty, so that China's territory was substantially expanded in the west and north for the first time.
