There are three theories about Huang taiji's sudden death: one is due to illness, the other is the conspiracy between Dourgen and Da Yuer, and the third is the grief of the death of the sea. After Huang taiji succeeded to the throne, he fought for years, and it was common to work in spite of illness. Generally, he drank and ate meat in a big bowl. Therefore, Huang Taiji actually has diseases such as high blood pressure and is very obese. I heard that the horse he rode in wartime was different from others, which is enough to show that his obesity is very serious.

Moreover, as the emperor at that time, he must have worked very hard, especially because of the constant war. He was a good emperor at the most important time, which made it more difficult for him. Because I was sick, I stayed up all day, too tired to work, and it was not impossible to die suddenly.

The death of the sea also caused great harm to him, and it is also possible that he will eventually die of illness. Huang taiji should be regarded as an infatuated person in history. Although the woman he likes is a widow, she still gets his exclusive favor. So when he learned that Hailanzhu was dead and came back, he fell off his horse and vomited blood. Back in the palace, he was even more haggard and depressed, and in poor health, and finally died of depression.

Others say that someone else killed Huang Taiji. In fact, I think this statement is not credible. Because there is no connection between Dourgen and Dayu in history, it is impossible for them to cooperate to kill Huang Taiji. Especially for her, Huang taiji's death is not good for her at all, so this statement is not valid, and the most likely ones should be the above two.
