Coup D'etat Against Liang Ji
As the years went by, Emperor Huan became increasingly disgruntled at Liang Ji's control of the government, and was also angered by Empress Liang's behavior. Because of her position as Empress Dowager Liang and Liang Ji's sister, Empress Liang was wasteful in her luxurious living, far exceeding any past empress, and was exceedingly jealous. She did not have a son, and because she did not want any other imperial consorts to have sons, if one became pregnant, Empress Liang would find some way to murder her. Emperor Huan did not dare to react to her due to Liang Ji's power, but rarely had sexual relations with her. In 159, angry and depressed that she had lost her husband's favor, Empress Liang died.
That would start a chain of events that would lead to Liang Ji's downfall later that year. Liang, in order to continue to control Emperor Huan, had adopted his wife's beautiful cousin (the stepdaughter of her uncle Liang Ji (梁紀—note different character despite same pronunciation)), Deng Mengnü (鄧猛女), as his own daughter, changing her family name to Liang. He and Sun gave Liang Mengnü to Emperor Huan as an imperial consort, and, after Empress Liang's death, they hoped that she would be eventually created empress. To completely control her, Liang Ji planned to have her mother, Lady Xuan (宣), killed, and in fact sent assassins against her, but the assassination was foiled by the powerful eunuch Yuan She (袁赦), a neighbor of Lady Xuan.
Lady Xuan reported the assassination attempt to Emperor Huan, who was greatly angered. He entered into a conspiracy with eunuchs Tang Heng, Zuo Guan, Dan Chao (單超), Xu Huang (徐璜), and Ju Yuan (具瑗) to overthrow Liang—sealing the oath by biting open Dan's arm and swearing by his blood. Liang Ji had some suspicions about what Emperor Huan and the eunuchs were up to, and he investigated. The five eunuchs quickly reacted. They had Emperor Huan openly announce that he was taking back power from Liang Ji and mobilized the imperial guards to defend the palace against a counterattack by Liang, and then surrounding Liang's house and forcing him to surrender. Liang and Sun were unable to respond and committed suicide. The entire Liang and Sun clans (except for Liang Ji's brothers Li Buyi and Liang Meng (梁蒙), who had previously already died) were arrested and slaughtered. A large number of officials were executed or deposed for close association with Liang—so many that the government was almost unable to function for some time. Liang and Sun's properties were confiscated by the imperial treasury, which allowed the taxes to be reduced by 50% for one year. The people greatly celebrated Liang Ji's death. What they did not know at that point was that this would not be an improvement of the political situation.
