The Lantern Festival rebellion against Cao Cao was a planned coup in 218 that turned a night of public celebration into an attempt to overthrow Cao Cao’s control of the court. Geng Ji, Wei Huang, and Jin Yi meant to seize the Royal Guard, obtain the emperor’s command against Cao Cao, and call Xuande to the imperial family’s aid. The revolt failed before those aims could be achieved: warning troops overwhelmed it by dawn, its principal participants were killed or captured, and Cao Cao used the aftermath to tighten his control over the court.

Causes and Conspiracy

Early in 218, Geng Ji and Wei Huang were appalled that Cao Cao had taken the title of king. They believed he had usurped imperial authority and sought allies among those who shared their opposition. They approached Jin Yi, who was also hostile to Cao Cao, but his friendship with Wang Bi, commander of the Royal Guard’s camp, made the conspirators wary. Only after establishing that Jin Yi was on their side did they settle on a plan.

The plot’s first objective was to kill Wang Bi and bring the Royal Guard over to the rebels. Jin Yi would then go to the emperor and ask him to ascend the Tower of Five Phoenixes, from which he could order Cao Cao’s capture. In parallel, two sons of the imperial physician Ji Ping, whom Cao Cao had had killed years earlier, would set fires throughout the city. Those fires were to signal an appeal to the city’s ordinary inhabitants to rise, seize the conspirators’ opponents, and protect the capital from a counterattack.

The plan also reached beyond the capital’s immediate defenses. Once the emperor had ordered the arrest of traitors, the rebels intended to attack Yejun, capture Cao Cao, and summon Xuande to rescue the imperial family. The conspirators armed around four hundred men from Geng Ji and Wei Huang’s staffs; another three hundred came from the Ji family. These forces were meant to turn a sudden assault into a broader uprising, but the plan depended on the rebels controlling the palace, the Royal Guard, and the public response at once.

A Coup beneath the Lanterns

The attack was set for the fifteenth night of the first month, the annual Lantern Festival celebrating the first full moon of the new year. Lanterns filled the capital, and the festive atmosphere left soldiers more relaxed than they would otherwise have been. As arranged, the conspirators were to begin their assault when fires appeared at Wang Bi’s camp.

Wang Bi was dining with his officers when the cry of fire announced the revolt. Realizing that a coup was underway, he mounted his horse and fled. An arrow wounded him as he escaped, but he reached Jin Yi’s residence ahead of his pursuers and beat on its closed door. The male household staff had gone out to join the uprising. Jin Yi’s wife, mistaking the visitor for her husband, called out to ask whether Wang Bi had been killed. The exchange exposed the danger waiting inside the house; Wang Bi turned away and rode to Cao Xiu, outside the city, to report the rebellion.

Cao Xiu gathered about one thousand men and rode to the capital’s aid. Meanwhile, the rebels’ fires had spread beyond their control. The Tower of Five Phoenixes caught fire, and the emperor had to hide in the centre of the palace. Cao Cao’s loyal troops held the main gate, while Xiahou Dun commanded a separate force of thirty thousand soldiers stationed outside the city. That force had been placed there after the fortune-teller Guan Lu warned Cao Cao of a terrible fire the following spring. When Xiahou Dun and his troops arrived, the revolt was doomed. By dawn it had collapsed: the Ji brothers were dead, Geng Ji and Wei Huang had been captured, and more than one hundred of their followers had been killed.

Punishment and Consolidation

After extinguishing the fires, Xiahou Dun’s men arrested the extended families of the five plotters. Cao Cao ordered the public execution of every member of each guilty family. As Geng Ji was led to his death, he threatened that he would return as a ghost to kill Cao Cao. His death and Wei Huang’s suicide became the rebellion’s stark final gestures: Wei Huang struck his head against the paving stones rather than submit to execution.

Cao Cao’s reprisals extended beyond the conspirators’ households. He assembled the palace officials at Yejun, where he had placed a red flag on the left and a white flag on the right. He instructed anyone who had come out to fight the fires to stand by the red flag, and anyone who had stayed home to stand by the white. Two thirds of the officials chose red, apparently believing that a claim of having helped would earn a reward. Cao Cao instead had them arrested, accusing them of having come out to support the rebels. He ordered their immediate execution; three hundred or more died that day. The officials at the white flag were rewarded and returned to the city relieved.

Wang Bi later died from his wound and received a ceremonial funeral. Cao Xiu was appointed commander of the Royal Guard. In the rebellion’s aftermath Cao Cao increased the size, splendour, and authority of his court. The attempted coup had aimed to make imperial authority the instrument of resistance; its defeat instead gave Cao Cao grounds to punish not only the conspirators but also officials whose actions he interpreted as disloyal.

Significance and Narrative Shape

The plot makes the struggle over the Han court concrete: its opponents believed Cao Cao had usurped imperial power, and their strategy centred on securing the emperor’s command before capturing Cao Cao. Yet the emperor was not restored to independent control. The rebellion’s collapse left the capital in the hands of Cao Cao’s loyal troops, and the mass executions that followed strengthened his authority rather than dislodging it.

The festival supplies the coup with both cover and a carefully staged signal. Lantern light and planned fires were meant to turn public celebration into a call to arms, but the actual blaze became a crisis that exposed the conspirators’ dependence on a sequence of coordinated successes. Wang Bi’s escape, Cao Xiu’s response, and Xiahou Dun’s much larger force broke that sequence before the emperor could issue the planned order or Xuande could be summoned. The red-and-white flag test then recast the aftermath as a new trap: an apparent opportunity to prove loyalty became grounds for execution. In the event’s progression, the failed attempt to reclaim political authority gives way to Cao Cao’s harsher demonstration of who commands it.
