[Why] In the mid and late Eastern Han, infant emperors ascended in succession, leaving consort kin and palace eunuchs to alternate control of central military and political power, and politics fell into deep darkness. Upright officials and Imperial Academy students formed the "pure discussion" movement against the consort kin and eunuchs. [What] The eunuch faction at court accused the upright scholar-officials of forming factions and slandering the throne, branding them as "partisans." Trusting the eunuchs, the emperor ordered the arrest and execution of hundreds of celebrated worthies and the lifelong prohibition of countless others from office. [Who] Li Ying and Chen Fan were loyal scholar-officials defending political conscience and feudal orthodoxy, revered by all educated society. The eunuch faction was the central tumor that dissolved the moral floor of the empire. [How] This sweeping political purge shattered the political contract and trust between the Han scholar-official class and the throne. It undermined the bureaucratic foundation of the Eastern Han and laid the fuse for the collapse of the empire.
