Brief: This article tells Zhuge Ke’s tragic rise and fall. As regent of Eastern Wu, he launched a disastrous northern campaign against Wei. His arrogance and tyranny turned allies into enemies. Sun Jun plotted against him and lured him to a fatal banquet. Zhuge Ke was killed, ending his turbulent regency.
Rise of Zhuge Ke
Upon his deathbed in 252 CE, Emperor Sun Quan of Eastern Wu entrusted state affairs to a coalition of regents: General-in-Chief Zhuge Ke (son of Zhuge Jin, nephew of Zhuge Liang), along with imperial clansmen Sun Hong and Sun Jun.
Tensions flared immediately – Sun Hong, resentful of Zhuge Ke’s influence, plotted to assassinate him and seize sole power.
But Sun Jun, though also ambitious, saw an opportunity. He secretly warned Zhuge Ke, who responded with chilling calm: he invited Sun Hong to his residence under the pretense of discussing state matters – and had him executed on the spot. With Sun Hong gone, Zhuge Ke assumed de facto control of Wu, installing the ten-year-old Sun Liang as emperor while ruling as supreme regent.
The disastrous northern campaign
In 253 CE, Zhuge Ke announced plans for a massive invasion of Cao Wei, aiming to capture Xincheng (north of modern Hefei, Anhui). Despite strong opposition from ministers – who argued that troops were exhausted from recent campaigns – he insisted:
“There cannot be two suns in the sky, nor two emperors on earth. With Sima Yi dead, Wei is weakened. We must not miss this chance!”
Ignoring counsel, he marched 200,000 soldiers north. But after three months of futile siege, Xincheng held firm. Summer heat turned camps into ovens; soldiers collapsed from heatstroke and dysentery. Morale plummeted, and desertions surged – some even fleeing to Wei.
When generals reported the crisis, Zhuge Ke accused them of lying and soldiers of feigning illness, threatening punishment. Fear silenced complaints – but accelerated desertions. Only after repeated imperial edicts did he reluctantly order retreat.
The withdrawal was chaotic: abandoned weapons, corpses along the road, suicides, and open muttering against Zhuge Ke. Yet he remained undeterred, planning another campaign upon return.
Tyranny at Court and Rising Resentment
Back in Jianye (Wu’s capital), Zhuge Ke vented his fury on officials. He summoned Sun Mo, the Palace Secretary, and berated him for issuing recall edicts:
“Who gave you the right to keep summoning me back?”
Terrified, Sun Mo resigned after falling ill from fright. Zhuge Ke then purged multiple ministers, replacing them with loyalists, and intensified military drills for a new invasion.
His autocratic rule alienated both court and populace. Even Sun Jun, his former ally in eliminating Sun Hong, now saw Zhuge Ke as a liability – and an obstacle to his own ambition.
The treacherous plot
Sun Jun approached the eleven-year-old Emperor Sun Liang, whispering:
“Zhuge Ke wields too much power. His arrogance breeds hatred. If we don’t act, disaster will come.”
Naive and impressionable, Sun Liang agreed. Together, they devised a trap: a royal banquet under the guise of reconciliation.
On the appointed day, Zhuge Ke received the invitation – and a secret warning from his palace informant, Zhang Yue:
“Today’s feast feels unusual. Be cautious.”
Zhuge Ke scoffed:
“What can that little Sun Jun do to me?”
Yet suspicion lingered. To guard against poison, he brought his own medicinal wine into the palace.
At the gate, he hesitated and claimed stomach pain. But when Sun Jun emerged smiling, saying,
“If you’re unwell, just go home.”
Zhuge Ke relaxed – interpreting kindness as safety – and entered, sword at his side.
The assassination at the banquet
During the feast, Zhuge Ke refused all offered wine, drinking only from his personal flask. After a few cups, Emperor Sun Liang excused himself, followed shortly by Sun Jun, who returned wearing only a short tunic – no long robes, ready for action.
Suddenly, Sun Jun shouted:
“By imperial decree – arrest Zhuge Ke!”
Zhuge Ke lunged for his sword – but Sun Jun struck first, slaying him instantly. Zhang Yue drew his blade in defense, slashing Sun Jun’s left hand before losing his right arm and being cut down by guards.
Sun Jun then forced a smile:
“The traitor is dead. All others are safe – resume drinking!”
No one dared lift a cup.
Sun Jun’s swift takeover
The next day, officials – terrified and leaderless – unanimously appointed Sun Jun as Chancellor. Within hours, he launched a purge:
- Zhuge Ke’s allies were executed or exiled.
- The court was cleansed of dissent.
- Power shifted entirely to Sun Jun and the imperial clan.
Thus ended the brief, turbulent regency of Zhuge Ke – a man whose military overreach, political rigidity, and refusal to heed counsel led not only to battlefield failure but to his gruesome end at a wine table.
As recorded in the Records of the Three Kingdoms (Sanguozhi) and later annotated by Pei Songzhi, this episode exemplifies how palace intrigue, youthful emperors, and unchecked ambition could unravel even the most powerful regents in the Three Kingdoms era.
