The saga of the Han dynasty’s collapse is a roller‑coaster of intrigue, treachery, and blood‑soaked upheaval. In this list we count down the 10 fateful events that set the stage for the Three Kingdoms era, from the secretive world of palace eunuchs to the blazing ruin of the Northern Palace. Grab a seat, because the drama is about to get deliciously intense.
10 Eunuchs Of The Northern Palace
The Han emperor called Luoyang home, ruling his affairs by day from the Southern Palace and retiring each night to the Northern Palace. That secluded wing housed dozens of consorts, each with her own private quarters, and a legion of maids who tended to every need. If the emperor fancied a maid, she could be elevated to consort, and if she bore a child, she rose even higher. No male outsider was permitted near these chambers—any fertile man caught in the women’s quarters faced certain death, and even adult princes were barred from overnight stays.
Only a select cadre of men could remain after dark: they served as guards or attendants, but with a stark condition—each had to be castrated, becoming a eunuch. These eunuchs became the emperor’s confidants, teachers, and caretakers. Families from across the empire sent their sons, freshly castrated, to gain a foothold at court, while others volunteered for the coveted proximity to power.
9 Meet The Knifers
Enter the “knifers,” a grim guild of specialists who offered to remove a man’s genitals for a fee. Before each operation they asked the hopeful three times, “Do you regret this?” A flinch meant cancellation; a steady answer earned a swift, brutal slice down to the base of the organ.
After the cut, a metal plug was jammed into the urethra and the wound bandaged. For three agonising days the new eunuch could neither drink nor urinate. On day three the plug was removed, unleashing a torrent of urine—if nothing flowed, infection meant certain death. Occasionally, eunuchs had to present their severed parts for inspection, preserving them in sealed boxes. Losing one’s “precious” meant a clandestine purchase of a replacement or borrowing from a fellow eunuch.
8 Eunuchs Corrupt The Young Princes
Derogatory jibes like “a teapot without a spout” or “a dog without a tail” were sly insults aimed at eunuchs. Their high‑pitched voices, beardless faces, and clumsy gait made them easy targets for mockery. Freshly castrated eunuchs were notorious for losing control of their bladders, spawning the common slur “smelly as a eunuch.” Royal consorts sometimes kept juvenile eunuchs as pets, even dressing them like little girls.
Older eunuchs, however, were entrusted with raising the empire’s princes. The belief was that a man who could not sire children would lack ambition for power. In reality, eunuchs were just as susceptible to corruption. They cultivated dependence in the young heirs, whispering that enemies lurked everywhere and that only their eunuch caretakers could be trusted. Emperor Ling, who ascended at twelve in AD 168, relied heavily on their counsel.
7 Hidden Mansions
In AD 169, scholars publicly denounced the eunuchs’ grip on power. The eunuchs, fearing exposure, persuaded Emperor Ling that these scholars plotted treason. Over a hundred leading scholars were arrested and executed; the rest lost all civil rights, and future scholars were barred from office.
The eunuchs turned the palace into a personal empire: they bought and sold official posts, infiltrated the military, and plundered the treasury. Ling adored the eunuchs Zhao Zhong and Zhang Rang, calling them his “mother and father.” They convinced him never to ascend the towering palace roofs, lest he glimpse the massive mansions they were secretly constructing for themselves (see the pottery model above).
Bankrupt from their excesses, the empire needed cash. In AD 178 Ling began selling public offices to the highest bidders. Many buyers could not pay outright, so Ling offered installment plans, thrusting them into debt. To repay, these officials resorted to embezzlement and bribery, further draining the state.
6 Brothers Of The Faith
Emperor Ling embarked on a grand project of imperial gardens, demanding costly tributes from the provinces. Local governors, pressed to meet these demands, levied crushing taxes on the populace. Meanwhile, floods and famine ravaged the land, forcing many into banditry. Ling hoarded the empire’s wealth, siphoning it into a federal reserve.
Amid the misery, a provincial doctor named Zhang Jue witnessed the suffering and experienced a spiritual awakening. He became a Taoist faith healer, urging people to confess sins for self‑healing. His younger brothers, also physicians, joined his mission, spreading the message far and wide. Their following swelled to hundreds of thousands.
Zhang Jue prophesied a yellow sky heralding the Han’s demise and the rise of a utopian kingdom. His followers donned yellow scarves, symbolizing the impending celestial shift, and prepared for armed revolt.
5 The Yellow Turban Rebellion
Zhang Jue’s fervent followers alarmed imperial ministers, who begged Emperor Ling for action. Ling, indifferent, continued imposing heavy taxes. The rebels spread a prophecy: “The azure sky dies, a Yellow Heaven rises. In the year jiazi, great fortune will come.” They wrote the year jiazi in chalk on government buildings and city gates.
Forming a shadow government, the rebels infiltrated the court, plotting to overthrow the empire. Their scheme leaked; Ling ordered the conspirators executed and dispatched troops to arrest Zhang Jue and his brothers.
Facing imminent capture, Zhang Jue launched the rebellion early. Though chaotic and poorly coordinated, the sheer numbers of rebels allowed them to seize cities and control vast territories. While Ling proved a poor ruler, his military commanders were not, and they began to respond forcefully.
4 Rise Of The Legendary Heroes
The Yellow Turban war birthed legendary figures later immortalized in Romance of the Three Kingdoms. Liu Bei, a charismatic folk hero, rallied a volunteer army to defend the crumbling empire. Meanwhile, Chancellor Cao Cao commanded a cavalry that enforced bans on cults, and his strategic insights later appeared in The Art of War.
Zhang Jue’s brothers fell in battle, and Zhang Jue himself died under mysterious circumstances. Though the rebellion was suppressed, the devastation was immense: hundreds of thousands perished, cities lay in ruins, and bandits roamed unchecked. Overwhelmed, Ling delegated self‑governance to local leaders, granting them expanded political and military authority. These empowered warlords earned the admiration of their people, eclipsing loyalty to the emperor.
Emperor Ling and the eunuchs, however, continued to levy oppressive taxes, keeping the common folk under strain.
3 A Trap
He Jin, brother to the empress, commanded the armies that quelled the Yellow Turbans. Afterward, he was elevated to commander‑in‑chief, wielding massive political clout. His primary objective: eradicate the eunuch faction.
In AD 189, Emperor Ling fell gravely ill, leaving two potential heirs. Prince Xie, the son of a favored consort, enjoyed eunuch support; Prince Bian, the empress’s son, lacked such backing. Ling died before naming a successor. Fearing He Jin would install Prince Bian, the eunuchs plotted murder.
They forged a summons from the empress, luring He Jin to the palace. Upon arrival, He Jin encountered Pan Yin, an old friend and eunuch‑affiliated soldier, at the gate. Pan Yin’s terrified expression prompted He Jin to feign illness and retreat. From a distance, He Jin declared Prince Bian emperor, setting the stage for further treachery.
2 The Eunuch Suicides
The tension between He Jin and the eunuchs escalated. He Jin petitioned his sister, the Empress Dowager, to execute all eunuchs, but she was allied with them. He Jin threatened her, calling in frontier warlord Dong Zhuo to encircle the palace with his forces.
Terrified, the eunuchs attempted a daring ambush, slaying He Jin within the palace walls. In retaliation, He Jin’s allies stormed the palace, slaughtering any eunuch they could locate. The most powerful group, known as the Ten Attendants, fled with the emperor and Prince Xie. Their flight led them to the Yellow River, where they were cornered. With no escape, the eunuchs chose to drown themselves, ending their lives in the river.
1 The Northern Palace Burns
While officials escorted the emperor and Prince Xie back to the palace, warlord Dong Zhuo intercepted them with a formidable army. The emperor, paralyzed by fear, could barely speak; Prince Xie answered Dong Zhuo’s questions calmly and clearly. With both in his grasp, Dong Zhuo marched into the capital, commandeering the leaderless forces of He Jin and the eunuch allies.
Dong Zhuo forced the emperor to abdicate, later poisoning the former ruler and his mother. He installed Prince Xie as a mere puppet, while he declared himself chancellor, brandishing a sword into council meetings and refusing to remove his shoes. He even slept in Emperor Xian’s bed and consorted with the emperor’s maids as his troops ravaged, raped, and slaughtered the city’s inhabitants.
When the populace could endure no more cruelty, they rose against Dong Zhuo. The empire fractured, and the heroes of the Yellow Turban Rebellion rallied their followers. Dong Zhuo fled the capital, setting fire to the Northern Palace as he escaped, sealing the Han dynasty’s final, tragic chapter.
