When people think of Gongsun Zan in the Romance of the Three Kingdoms, many immediately associate him with Liu Bei, as the two were classmates under the famed scholar Lu Zhi. Though their relationship was that of schoolmates, Gongsun Zan never achieved the same legendary status as Liu Bei—largely because Luo Guanzhong, the author of Romance of the Three Kingdoms, minimized his role, portraying him as a minor warlord.
Yet historically, Gongsun Zan was a major power in northern China, second only to Yuan Shao before Cao Cao’s rise. A man who once stood on the brink of greatness, he ultimately met a tragic end—defeated, isolated, and consumed by fire in his own fortress.
So why did such a promising figure fall so completely?
The early promise
Gongsun Zan was born in Liaoxi Lingzhi (modern-day Qian’an, Hebei), into a noble family. However, due to his mother’s low social status, he began his career as a clerk (Shu Zuo) under Governor Hou of Zhuo Commandery(Zhuojun), responsible for handling official documents.
Despite his humble start, Gongsun Zan was handsome, articulate, and sharp-minded. He could summarize multiple reports in a single briefing without error, impressing Governor Hou so deeply that the latter had his daughter married to Gongsun Zan.
This marriage changed Gongsun Zan’s fate. With his father-in-law’s support, he became a student of Lu Zhi, one of the most respected scholar-official of the time. It was during this period that he met Liu Bei, forming a bond that, though not deeply explored in the novel, would echo through history.
Loyalty Rewarded
Later, Gongsun Zan was recommended by Lu Zhi to Governor Liu Qi of Zhuo Commandery, who appointed him as Shangji Li—a far more prestigious role involving communication between the local government and the imperial court. This position allowed him to build a valuable network of political connections.
But soon, disaster struck: Governor Liu Qi was convicted of a crime and exiled to Rinan Commandery, a remote region far to the south.
Most officials would have distanced themselves from a disgraced superior. Not Gongsun Zan. He disguised himself as a servant and escorted Liu Qi all the way to Rinan Commandery, a bold act of loyalty that deeply moved the governor.
Fate intervened: Liu Qi was pardoned and reinstated before reaching his destination. Grateful, he recommended Gongsun Zan as a Xiaolian—a Confucian moral exemplar—a prerequisite for high office in the Eastern Han Dynasty.
Soon after, Gongsun Zan was appointed Changshi of Liaodong, a military post second only to the governor. He led campaigns against the Wuhuan tribes in the north, earning fame for his bravery and tactical skill. His reputation as a rising star in the northern military was firmly established.
The rebellion and the turning point
In 184 AD, the Yellow Turban Rebellion erupted, followed by a rebellion in Liang Province(Liangzhou). The Han court ordered Zhang Wen to suppress it. Since Zhang Wen’s forces were mostly infantry, the court summoned Gongsun Zan with 3,000 cavalry for reinforcement.
But en route, Gongsun Zan’s troops were incited to mutiny by Zhang Chun and others. In response, the court appointed Liu Yu, a respected member of the imperial clan, as Governor of You Province(Youzhou), to quell the rebellion.
Through a mix of military action and pacification, Liu Yu succeeded swiftly, and Gongsun Zan, having contributed significantly to the campaign, was promoted to a general (Fenwu General) and enfeoffed as Marquis of Ji. He was placed in command of You Province’s armies—effectively becoming the second-in-command under Liu Yu.
The betrayal of Yuan Shao
When Dong Zhuo seized power and moved the capital to Chang’an, Yuan Shao rallied a coalition of warlords to oppose him. Though framed as a campaign to restore the emperor, it was, in truth, a struggle for control over the Han throne.
With Dong Zhuo in control of Emperor Xian, Yuan Shao and Han Fu, Governor of Ji Province, conspired to install Liu Yu as emperor. But Liu Yu refused, recognizing that without an army, he would be a mere puppet.
Unbeknownst to Han Fu, Yuan Shao secretly contacted Gongsun Zan, proposing a joint invasion of Ji Province under the pretense of fighting Dong Zhuo. They agreed to split Ji Province after its conquest.
Gongsun Zan, eager to expand his domain, approached Han Fu to request passage. But Han Fu, suspicious, refused and fortified his borders.
At that moment, Gongsun Zan learned the bitter truth: Yuan Shao had already seized Ji Province through political manipulation, forcing Han Fu to surrender. Worse, Yuan Shao later had Han Fu killed.
Gongsun Zan had been used as a pawn. When he demanded his share of Ji Province, Yuan Shao flatly refused.
Enraged, Gongsun Zan publicly denounced Yuan Shao, exposing his hypocrisy and treachery, including the failed attempt to make Liu Yu emperor. This earned him sympathy from Han Fu’s former officers, including Zhao Yun, who joined Gongsun Zan during this period.
The Battle of Jieqiao
In 191 AD, Gongsun Zan launched a full-scale war against Yuan Shao—culminating in the Battle of Jieqiao.
Confident in his elite cavalry, the famed “White Horse Volunteers,” Gongsun Zan believed victory was assured. But Yuan Shao’s general Qu Yi used crossbowmen and disciplined infantry to break the cavalry charge.
The result was a crushing defeat for Gongsun Zan. His army was shattered, and his momentum broken.
The fall of Liu Yu
Even more disastrous was what followed. Liu Yu, still nominally Governor of You Province, saw Gongsun Zan weakened and mobilized his loyalists to eliminate him.
But Gongsun Zan learned of the plot in advance. A fierce battle ensued, and Liu Yu was captured.
Here, Gongsun Zan made a catastrophic error. Despite Liu Yu’s status as a Han royal and his superior, Gongsun Zan executed him and his entire family. Even worse, he sent Liu Yu’s head to Chang’an as a trophy, a grotesque display of arrogance.
This act ignited widespread outrage. Former officials and soldiers of Liu Yu rose in rebellion, and many fled to join Yuan Shao.
Instead of crushing the rebellion, Gongsun Zan made another baffling decision. When a loyal general was surrounded by rebels and begged for help, Gongsun Zan refused to send aid, declaring:
“If I rescue them now, they will grow dependent. They must fight to the death on their own.”
This cold, inhumane logic destroyed morale. His officers realized he valued discipline over loyalty, and many began to doubt his leadership.
The siege of Yijing
With internal unrest and Yuan Shao’s forces advancing, Gongsun Zan was forced to retreat to Yijing, where he built a massive fortress with tall towers and deep moats, refusing to engage in open battle.
For years, he hoarded supplies and waited, believing he could outlast Yuan Shao.
But Yuan Shao was patient. In 198–199 AD, he feigned the arrival of reinforcements from Gongsun Zan’s son, luring him out of his fortress.
Gongsun Zan took the bait. Leading a force to meet the “relief army,” he was ambushed and defeated.
Trapped and hopeless, Gongsun Zan killed his family, then climbed to the top of his tower and set it ablaze, perishing in the flames.
Thus ended the life of a man who once commanded vast armies and dreamed of empire.
Why did Gongsun Zan fail?
Gongsun Zan’s downfall was not due to a lack of early success or military talent. Rather, it stemmed from fundamental flaws in character and strategy:
- Shortsighted ambition: He focused on immediate gains (like Ji Province) without a long-term vision.
- Lack of strategic depth: After Jieqiao, he retreated into isolation instead of seeking alliances or reforming his forces.
- Poor leadership: His refusal to rescue his men revealed a lack of empathy and loyalty, alienating his officers.
- Moral failure: The murder of Liu Yu, a respected Han loyalist, cost him legitimacy and support.
Unlike Liu Bei, who inspired loyalty through benevolence and perseverance, Gongsun Zan ruled through fear and rigidity. It is no surprise that both Liu Bei and Zhao Yun eventually left him—not out of disloyalty, but because they recognized a leader who could not build a lasting legacy.
