A thousand years ago, Emperor Wu of Han Liu Che sent troops to attack the Xiongnu, so that the Xiongnu had to surrender, but also had to flee west, and then successfully opened up the Silk Road, but these achievements can not be attributed to Emperor Wu of Han alone, if there is no Han Wen Emperor and Han Jing Emperor "Wen Jing rule", Han Wu Emperor may not be able to achieve such achievements, and since Han Wu Emperor, the Western Han Dynasty has collapsed, rapidly to decline.
A hundred years ago, the Qianlong Emperor opened the "Kangqian Shengshi", which was the last prosperous era of China's ancient feudal dynasty, in the same way, if there was no Kangxi Emperor's conquest outside, the Yongzheng Emperor filled the national treasury, and only the Qianlong Emperor may not be able to develop the Qing Dynasty to the highest peak, but as an emperor, the Qianlong Emperor naturally also had some strategy.
The Kangxi Emperor personally conquered northern Mobei three times, all of which won victories, preventing the Dzungars from advancing eastward, but did not completely eliminate the hidden dangers, and after the defeat of the Dzungar noble leader Gardan (also a descendant of Yixian), his nephew Ceyu Alabutan succeeded him as the Taiji of the Dzungars, and gradually developed and grew and then clashed with the Qing Dynasty.
During the reign of the Yongzheng Emperor, he also wanted to eliminate the hidden dangers of the Dzungars, and experienced 4 large-scale battles, among which the defeat of Hetongpo left a bitter lesson, the Qing army of tens of thousands of elite soldiers only more than 2,000 retreated back to Kobdo, Yongzheng thirteen years (1735), the Yongzheng Emperor and the Dzungar Empire signed a peace treaty, the two coexisted peacefully for decades.
In the same year, the Yongzheng Emperor died and Qianlong ascended the throne, and the Qianlong Emperor greatly admired his grandfather, the Kangxi Emperor, and also intended to fulfill the last wishes of his grandfather and father, and the Yongzheng Emperor accumulated a lot of money for the Qianlong Emperor, and the supply of military salaries was completely no problem.
At the time of the civil unrest in Dzungar, the Qianlong Emperor felt that it was time to send troops, but the courtiers dissuaded one after another, first, because the defeat of Hetongpo left a huge impact on the qing court ministers; second, because the Qing Dynasty and the Dzungars shared twenty years of peace, which was also beneficial to the Qing Dynasty.
There was no war, the two sides had a lot of trade exchanges, mutual benefit and win-win results; once the war began, the peaceful life on the frontier of the Qing Dynasty disappeared, and the Qing army had not fought in 20 years, and what were the chances of victory? If this battle is lost, it will be the Qing Dynasty that will collapse, and will the Qianlong Emperor be the emperor of the fallen country?
However, the Qianlong Emperor insisted on sending troops to Dzungar, and faced the courtiers, saying, "Ai Qing, you will listen to it once." "In the twentieth year of Qianlong (1755), the Qianlong Emperor sent 50,000 and 140,000 horses to attack Dawaqi, who was self-proclaimed Great Khan of the Dzungars, and Dawazi did not expect that the Qing army would insert a foot at this time, and thus be defeated and captured.
Two years later, the Qianlong Emperor sent troops to attack from Balikun and other places, and Amuel Sana, the grandson of Alamutan, was defeated and defected to Tsarist Russia, and then fell ill and died. The Qing army also took advantage of the victory to attack, the Qing Dynasty pacified the overall situation of Dzungar, and the Qianlong Emperor immediately dispatched Manchu officers and soldiers to the south to fight against the size and size of the rebellion on the south road of the Tianshan Mountains, and by 1759, the rebellion in the north and south of the Tianshan Mountains had been quelled, and the hidden dangers of the Dzungars had been completely eliminated.
As a result of this war, the Qianlong Emperor raised his power in the southwest, and after the large and small Jinchuan rivers were pacified, the chaotic and strife situation was also brought to an end; in the middle of the Qianlong Period, agriculture, handicrafts, and commerce in all regions of the country were greatly developed, the population surged, and a prosperous scene was opened up, opening up the "prosperous era of Kangqian."
However, after the Qianlong Emperor reached middle age, he was so happy that he was very happy and vigorous in civil engineering, and the six Jiangnan were only for pleasure, and the pomp was very large, and the late Qianlong period turned from prosperity to decline, especially the complete closure of the country, and the Qing Dynasty people did not know what kind of development abroad had ushered in.
