The Poisoned Chalice of Power

When Emperor Huan of Han (Liu Zhi) eliminated the tyrannical regent Liang Ji in 159 CE, it seemed a moment of deliverance for the Eastern Han dynasty. Yet the purge that followed—executing hundreds of Liang’s associates and emptying court offices—created a vacuum soon filled by an even deadlier force: eunuchs. The emperor, having relied on five eunuchs (Zuo Guan, Tang Heng, Shan Chao, Xu Huang, and Ju Yuan) to overthrow Liang, rewarded them with noble titles, vast estates, and unchecked authority. Thus began the dynasty’s irreversible descent into factional strife and moral decay.

The Eunuch Ascendancy

Liu Zhi’s court became a grotesque parody of governance. When upright scholars like Chen Fan recommended virtuous candidates (Xu Zhi, Jiang Gong, Wei Zhu, Yuan Hong, Li Tan) to replenish the bureaucracy, all refused, seeing the regime as merely exchanging “the left hand for the right.” The emperor, indifferent to their defiance, expanded eunuch appointments, preferring their obsequiousness to scholars’ principled dissent.

Chen Fan, the incorruptible Grand Commandant, embodied the conflict. His famous retort as a youth—”A true man should sweep clean the world, not just one room!”—became his life’s creed. Yet his rigid virtue proved ill-suited to the serpentine politics of Luoyang. After surviving Liang Ji’s wrath (having once flogged the regent’s envoy to death), Chen now faced a more insidious enemy.

The First Factional Proscription (166 CE)

The eunuchs’ misrule reached a crisis when they exploited an impending amnesty to shield criminals like Zhao Jin and Zhang Fan. Magistrates Liu Zhi and Cheng Jin, defying the pardon, executed the offenders—only to be condemned by eunuch-controlled courts. Chen Fan’s protests fell on deaf ears; Emperor Huan, ensnared by eunuch flattery, authorized mass arrests of “factionalists” (dangren).

The persecution backfired spectacularly. Scholar-officials like Li Ying, Du Mi, and Fan Pang wore their arrests as badges of honor. General Huangfu Gui even petitioned to be listed among the proscribed, declaring: “If Zhang Huan is a factionalist, then I am his accomplice!” Under torture, Li Ying turned the tables by implicating eunuch families, forcing a stalemate.

The intervention of Dou Wu—Empress Dou’s father—broke the deadlock. His searing memorial comparing eunuchs to Qin’s corrupt Zhao Gao shocked the court. Combined with eunuch infighting (notably Wang Fu’s sympathy for the imprisoned), this compelled a mass release of prisoners in 167 CE—though they remained barred from office.

The Second Proscription (168–184 CE)

Emperor Huan’s death in 168 CE brought the 12-year-old Liu Hong to power under a regency led by Dou Wu and Chen Fan. Their attempt to purge eunuchs through legal channels proved fatal. Hesitation doomed them: Dou’s daughter, Empress Dowager Dou, balked at exterminating all eunuchs, while Chen’s public denunciations alerted the enemy.

Eunuch counterstroke was swift. Zhu Yu’s fabricated coup accusation triggered a night of knives in September 168 CE. Wang Fu butchered Chen Fan; Dou Wu’s garrison mutinied; and the regents’ severed heads adorned Luoyang’s gates. The aftermath saw thousands slaughtered—from Dou’s clansmen to “Eight Paragons” like Li Ying.

The Eunuch Paradox

Why did eunuchs invariably corrupt power? Castration’s psychological scars bred pathological compensations. Deprived of lineage, they fixated on wealth and control. Isolating emperors (like calling Liu Hong “Father” and Zhao Zhong “Mother”), they turned courts into echo chambers. By 184 CE, the “Ten Regular Attendants” monopolized governance while Liu Hong played merchant in palace markets—unaware his empire burned.

The Yellow Turban Revolt (184 CE)

Zhang Jue’s millenarian uprising exposed the regime’s rot. Though crushed by Huangfu Song and Lu Zhi (temporarily), the rebellion’s legacy endured. The court’s response—selling offices and taxing peasants—only deepened despair. When Liu Hong died in 189 CE, leaving a child emperor to warlords, the Han’s fate was sealed.

Legacy: The Cost of Purity

Chen Fan and Dou Wu’s tragedy lay in their absolutism. Their refusal to compromise with imperfect systems—whether through coalition-building or gradual reform—left them outmaneuvered. The Eastern Han’s collapse warns that moral righteousness, untempered by pragmatism, can become its own undoing. As the Hou Hanshu lamented: “The gentleman sweeps clean his own doorstep, but the empire’s dust remains.”
