He Jin
In the summer of 189, after learning that Jian Shuo wanted to assassinate him, He Jin and his supporters launched a preemptive move against the eunuch and had him arrested and executed. Months later, Yuan Shao suggested to He Jin to eliminate the eunuch faction and consolidate power. Although Empress Dowager He strongly objected to He Jin's plan, the General-in-Chief, acting on Yuan Shao's advice, attempted to push his idea. He instigated a few regional warlords to lead their troops into the vicinity of Luoyang, the imperial capital, and openly demand that the eunuchs be executed – in the hope of pressuring Empress Dowager He into agreeing. The empress dowager, however, sided with and protected the eunuchs. In retaliation, the eunuchs hatched a plot to assassinate He Jin: they issued a fake imperial order in Empress Dowager He's name, instructing He Jin to enter the imperial palace, where he fell into an ambush and was killed by the eunuchs.
