In Chinese history, the Western Zhou Dynasty and the Qing Dynasty had many similarities: they both took advantage of the other party's internal strife to take advantage of the situation, and both were based on the mode of snack. And, interestingly, in the early days of the dynasty, there was a phenomenon of regency.
In the second year of the Western Zhou Dynasty's destruction of Shang (some books say that it was that year, but the difference in time was a few months, it did not affect **) King Wu of Zhou died, and King Cheng of Zhou became the new Son of Heaven. At this time, the forces of Yin Shang's hometown that planned to restore the Shang Dynasty can be described as one after another. And King Cheng of Zhou was still a child, of course, he couldn't deal with such a complicated situation, so in the early years of the Western Zhou Dynasty, there was a situation of Zhou Gong's auxiliary government - of course, it is generally believed that Zhou Gong's auxiliary government was authorized by King Wu of Zhou on his deathbed, and only started auxiliary government. But even so, there are still rumors that the Duke of Zhou intends to usurp the throne and provoke the relationship between King Cheng of Zhou and the Duke of Zhou.
The situation in the Qing Dynasty was similar: before the Qing army entered the customs, the Qing emperor Huang Taiji died violently. However, before his death, Huang Taiji did not give an explanation for what happened after his death: that is, who will inherit the throne? As a result, the Qing court argued and finally decided to appoint the child Fulin as emperor and Dolgon as regent at the same time—the result of a compromise between many forces.
But the endings of the Duke of Zhou and Dolgon were very different: after the death of the Duke of Zhou, the kings of the Zhou Dynasty and even later generations also regarded the Duke of Zhou as a sage. The ceremonial laws of the Duke of Zhou were also regarded by later generations as the de facto "Confucian Constitution", and soon after Dorgon's death, he was dug up by Emperor Shunzhi.
So the question is, why are they both auxiliary ministers, and the situation of Duke Zhou and Dolgon is completely different?
Personally, I think that the situation in the Western Zhou Dynasty and the situation in the Qing Dynasty are fundamentally different, that is, the pattern is very different.
You must know that in the third dynasty of the Xia and Shang dynasties, the distribution of power and resources was the model of Shiqing Shilu: that is, nobles were born nobles, and Li people were born to be Li people, and there was basically no possibility of counterattack. For the common people, this situation means that the class has solidified to the level of diamonds, and there is no possibility of turning the tables around, but for the interest groups, it is the best model: that is, the nobles can enjoy the glory for generations.
Therefore, although King Zhou Cheng had suspicions about Zhou Gong, from the perspective of the overall environment, even if Zhou Gong subjectively had the idea of usurping the throne, he would be limited by objective conditions - after all, people with bad rules rarely end well. In this large scope, the Duke of Zhou also played a positive role in the stability of the Western Zhou Dynasty, and did not have much impact on the personal prestige of King Zhou Cheng. Therefore, the relationship between King Zhou Cheng and Duke Zhou can end in a harmonious ending.
Before the Qing Dynasty entered the customs, Huang Taiji revised the power structure and system of the Qing Dynasty in accordance with the structure of the Ming Dynasty. Therefore, for the Qing Dynasty monarchs, if they want to sit firmly, they need to establish their prestige.
At the beginning of the reign of Emperor Shunzhi, the power was in the hands of Dolgon. After Emperor Shunzhi came to power, if he wanted to establish his prestige, it was necessary to liquidate Dorgon. Therefore, this difference in background led to the tragedy of Dorgon's death. A similar example is Zhang Juzheng of the Ming Dynasty - Zhang Juzheng was nominally the first minister in the early years of the reign of Emperor Wanli, but in fact he was also a regent.
In addition, unlike Duke Zhou, many of Dolgon's behaviors made Emperor Shunzhi feel that the reason why Dolgon did not usurp the throne and claim the throne was not because he didn't want to, but because he didn't complete the accumulation and didn't reach the time window.
Although the Qing Dynasty followed the Ming Dynasty in the system, there was another characteristic of the power structure, that is, the attitude of the Eight Banners aristocracy was very important. If Dorgon wants to be emperor, he needs to at least consider gaining the approval of the nobles of the Eight Banners. And during the regency of Dolgon, there were indeed many acts of suppressing other Eight Banner nobles and wanting to further increase their power - such as killing Huang Taiji's eldest son Haoge.
Therefore, Emperor Shunzhi thought that if Dolgon lived a few more years, it was unknown whether he could continue to be emperor or even save his life.
Therefore, Emperor Shunzhi wanted to liquidate Dolgon.
