The first successful usurper was Wang Mang. However, due to my improper measures, I finally died and lost my reputation.
The last person who succeeded in usurping the throne was Zhao Kuangyin. Because of his skill, his dynasty lasted for hundreds of years, and later generations saw that he was Bai Lianhua.
These usurpers treated the previous dynasties best, or follwed, xelloss and Sima Yan. In the future, a crab is not as good as a crab, and the extinction interpretation is incisive.
Personally, I think that among these usurpers, Li Bian is the most ferocious one. Other usurpers either give you a knighthood like Xelloss Sima Yan, and then send someone to watch you. If they are honest, they won't bother you, or like Emperor Wu of Song and Xiao Daocheng, they will kill everyone, and people will die like lights.
But after Li Bian usurped the throne, how did he treat his former master? He moved his men, women and children to Hailing, forbidding them from entering Yongning Palace, guarding them and keeping outsiders out, that is, locking up Yang's people and forbidding contact with outsiders. These more than ten years of imprisonment directly led them to become a primitive society, with men and women matching each other. When people heard about it, they felt sorry for them.
Later, Guo Rongnan wrote to appease Yang. Li Jue's son, Li Jing, worried that he would take advantage of Yang's family, so he sent someone to kill all the imprisoned Yang. Yang Xingmi, a hero I, had miraculous powers. He traveled 300 li a day and was left childless by Li.
It's better to kill everyone when you usurp the throne!
