In ancient Chinese history, the status of women was always inferior, so women who could be written into history books were generally extremely powerful. For example, Lü Hou, who is related to today's topic, is an unusual figure, she is the first recorded empress and empress dowager in Chinese history.
Later generations of Lü Yan's evaluation was extremely high, and Li Shang, the son of the chancellor of the early Han Dynasty, commented that Emperor Gao and Lü Hou jointly determined the world. Liu Bang even commented that "Lü Hou is true and the lord is the master." Others put her together with Emperor Hui of Han and Emperor Wen of Han, because they "took advantage of the initial determination of the world, rested with the people, and deeply held the virtue of flexibility and perseverance."
At the beginning, in order to strengthen his rule, Lü Yan drove out all those who had the strength to threaten him, including Lady Qi, Liu Ruyi, and even Liu Bang's son. In this bloody storm, there was only one Han clan relative who repeatedly offended Lü Hou but was not persecuted, and he was Liu Zhang.
Liu Zhang was the grandson of Liu Bang and the second son of Liu Fei. Because Lü Hou felt that Liu Zhang was a rude person, had no plans, and did not pose a threat to her. Also, Liu Zhang's wife is also a member of the Lü clan, and Lü Hou will naturally take care of some.
After Lü Yan's death, the Lü family plotted to usurp the throne, and after Liu Zhang learned of it, he immediately led an army into the palace, which eventually led to the Lü clan being killed, both men, women and children, and the Lü clan was also exterminated. I think that if Lü Hou knew that such a thing would happen before he died, I believe that he would definitely crush Liu Zhang's corpse into ten thousand pieces.
