What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
From today's point of view, the alternation of the last two dynasties in China is quite dramatic, and I believe that it is difficult for the Ming Dynasty people at that time to imagine that Jiangshan would fall into the hands of the Manchus outside Guanwai, which is due to the peasant uprising within the Ming Dynasty and the conspiracy that was still being carried out when several forces in the Southern Ming Dynasty were in danger.
Of course, within the Qing army, there were also a number of brave generals, such as the most famous Dolgun, as nurhaci's fourteenth son, Dolgun successively broke the Mongolian Chahar department, won a great victory in the decisive battle of Songjin in the Ming Dynasty, and commanded the Qing army to enter the pass in 1644.
At this time, Dolgun, like Cao Cao, had great prestige internally, and he was also the only two regents in the history of the Qing Dynasty, the other being Puyi's father Zaifeng. What makes people curious is that Shunzhi is only 6 years old, and the only people who support him are Xiaozhuang and a few other forces, why did Dolgun, in the case of pure blood, not learn from Ming Chengzu Zhu Di and directly seize the throne of his nephew? In fact, experts will tell you that you know who is behind him, and Dorgon has a powerful opponent, that is, Shunzhi's brother, Emperor Taiji's eldest son Hauge.
Compared with the Prince of Dorgon, Hauge's merits in Guannei were actually not inferior to those of Dorgon, and in the Battle of Ningjin in 1627, Hauge and the Ming army defeated the main force of the Ming army in the Battle of Jinzhou, and then he conquered the Mongol Guttabu nang, defeated it, and killed it, taking all his troops. Hauge used his troops boldly and bravely, once bypassing the Guanningjin Defense Line operated by the Ming Dynasty, leading the Eight Banners to detour through the interior and directly approach the city of Beijing, causing a sensation in the Ming Dynasty.
In 1636, Emperor Taiji was proclaimed emperor, and Hauge was made the Prince of Heshuosu, and by 1643, Emperor Taiji died suddenly, and before he could command an heir, Hauge and Dorgon became the biggest competitors to the throne.
Although the Qing Dynasty did not have the rules of succession of the eldest son, Hauge, with his excellent ability, won the recognition of most people, including Turg, Sony, Turai and other ministers, and had the support of the three banners of Zhenghuang, Yellow and Blue and the surrender of Han Chen, while Dorgon had a comparative advantage in military power, and the two were naturally tit-for-tat. Relations are extremely strained. Everyone understands that once the other party becomes the emperor, there is no place for them to die.
In the end, the two yellow flags, which were wavering, made a decision, that is, to take a compromise approach, li hauge's younger brother, that is, the 6-year-old Fu Lin, to become emperor, so as to ensure that it was the blood of the emperor Taiji to buy the throne, and at the same time, Dorgon's position would not be threatened, and considering the relationship between Empress Xiaozhuang, he could also win over the Mongols.
Both sides agreed to the proposal, and Dorgon and Hauge's supporters, Prince Zilharang of Zheng, were regent. After that, Haug repeatedly led his troops outside, and in 1647, he broke the peasant army and shot the leader Zhang Xianzhong with an arrow, because hauge's restraint made Itgon unable to further threaten the throne and missed the best opportunity.
However, Hauge eventually lost power in the competition with Dorgon, and was imprisoned in 1648 by Dorgon for concealing the fact that his subordinates had taken the blame and used the sinner's brother, and died in prison in April. However, he bought time for Shunzhi to gather his forces, and three years later, Shunzhi pro-government, disposed of Dorgon, and the unjust case he created was also revealed, and Hauge regained the title of Prince of Heshuosu and entered the Taimiao Temple.
