Huang Taiji is the founder of the Qing Dynasty, the mystery of the ascension of Huang Taiji is quite controversial in the field of history, many people think that his father Nurhaci originally wanted to pass the Khan throne to the fourteenth son Dolgun, but Huang Taiji forced the death of Dorgon's mother, usurped the Khan's throne, after The Emperor Taiji ascended the throne, he actively expanded externally, on the one hand, he consolidated relations with Mongolia, practiced Manchu-Mongolian intermarriage, and attracted a large number of Mongolian nobles, on the one hand, he stepped up his attacks on the Ming Dynasty, defeated the Ming army many times, and even forced the Chongzhen Emperor to recognize the Qing Dynasty. Attempts to sit on an equal footing with the Ming Dynasty.

In the end, he also actively co-opted the Han people, attracting a large number of strategists to serve him, such as Fan Wencheng, Hong Chengzuo, etc. under his surrender became the precursor of the Qing Dynasty's attack on the Central Plains, and The Emperor Taiji determined a very grand strategy at the beginning of his reign, preparing to conquer Korea and Southern Mongolia first, relieve the worries of the future, and then adopt the strategy of the Han strategists, make peace with the Ming Dynasty, carry out internal reform and rectification, strengthen and consolidate the regime, reuse the Han generals, gradually encroach on the Ming Dynasty, and finally destroy the Ming Dynasty in one fell swoop and enter the Central Plains.
Under the leadership of Huang Taiji, Huang Taiji won many victories in the process of fighting against Korea, the Ming Dynasty and Mongolia, the Elite of the Ming Dynasty outside the Guanwai was beaten by him and lost its combat effectiveness, the Ningjin Defense Line collapsed for a time, but at the critical moment when the Qing Dynasty entered the pass, Huang Taiji suddenly died suddenly, and the death of Huang Taiji made the Qing Dynasty with strong combat effectiveness lose its main heart at once and fell into internal chaos, Huang Taiji died very hastily without leaving any will, and did not determine the heir, which made the eight banner lords at that time want to move. They all wanted to seize the throne and stand on their own, the most powerful of which was the two teams of Dorgon and Hauge, and for the struggle for the throne, the two were intolerable, even to the point of fighting each other.
Fortunately, Dai Shan Lao Cheng plotted the country, grasped the situation at a critical moment, and finally determined That Fu Lin as emperor, the two took a step back, and there was nothing to say, in this court battle, the two formed a deep contradiction, which made the Qing Dynasty that was preparing to enter the customs to destroy the Ming Dynasty stagnate, and by the time the Qing Dynasty dealt with the internal contradictions, the Ming Dynasty had already been destroyed by Li Zicheng. So how did Huang Taiji die? Why did he die suddenly within a few days?
Regarding the cause of death of Huang Taiji, there are many theories in later generations, some people say that Huang Taiji was assassinated, and some people say that Huang Taiji died suddenly after being too tired, so what is the real cause of death of Huang Taiji? There is no clear reason given in the "Qing ShiLu", the death of an emperor is actually brushed over, which is very puzzling, and many historians have pointed out that before the death of Emperor Taiji, there was a non-negligible event, that is, when Emperor Taiji was 50 years old, his most beloved concubine died.
Emperor Taiji had fifteen women in his lifetime, and his favorite was the Borjigit clan, and Chongde named her Concubine Guanju Palace in the first year. Huang Taiji and Concubine Chen originally had a son, but died shortly after, which made Emperor Taiji grief-stricken, and in September of the sixth year of Chongde, Emperor Taiji was on the front line of Songjin, overheard that Concubine Chen was critically ill, and rushed back to Shengjing, by which time Concubine Chen was dead. Huang Taiji did not even see the last side of his most beloved woman, and the pain in his heart could be imagined.
At this time, Huang Taiji was actually exhausted, and since then Huang Taiji has often experienced unexplained coma, and on the second day of October of that year, he said to the kings and their wives and children: The mountains are crumbling, the wood is high, and the old wealth is declining. At this time, Huang Taiji already knew that his life had come to an end. On the ninth day of the first month of August in the eighth year of Chongde (Ming Chongzhen 16th year, 1643), Emperor Taiji died suddenly in the harem of Shengjing at the age of 52. A generation of heroes finally died of excessive grief and heartache for a woman, which is really a pity, and the children's love finally wanted the life of the founding emperor of the Qing Dynasty, no wonder even the historical materials are embarrassed to record it in detail!
