The Coalition against Dong Zhuo is an alliance of seventeen military leaders formed in response to Dong Zhuo’s seizure of power and crimes against the Han court and the people. Organized after Cao Cao circulates a call to arms, it gathers forces under Yuan Shao’s leadership and draws in Xuande and Sun Jian. Its campaign begins with a declared commitment to protect the imperial house, but competing ambitions soon break that unity: a dispute over the Imperial Seal drives Sun Jian away, and the alliance begins to dissolve before it can sustain a common front.

Causes and Formation

After escaping the immediate danger surrounding his attempt on Dong Zhuo, Cao Cao returns to his family home and seeks money to raise troops. His father cannot provide the funds, but a local notable helps secure them. Cao Cao then issues a fake edict claiming to come from the emperor, and volunteers begin to gather beneath a white banner bearing the words “Loyalty” and “Integrity.” The banner gives the new force a public language of service even as the call itself is fabricated.

Copies of the edict reach Yuan Shao, who brings an army of thirty thousand to join Cao Cao. Cao Cao follows with a proclamation urging the country’s leaders to unite against Dong Zhuo, accusing him of murdering the emperor, usurping the palace, and harming ordinary people. Seventeen military leaders respond and set out for the capital. The alliance is therefore built not by a single ruler’s command but through a call that circulates between regional powers, turning shared opposition into a temporary basis for cooperation.

Leaders and Common Purpose

Gongsun Zan joins the expedition while traveling toward the capital with fifteen thousand men. On the road he encounters Xuande, who has come to pay his respects as a local magistrate, together with his two sworn brothers and their troops. Gongsun Zan persuades Xuande to join the uprising. Xuande says he wants the honor of killing Dong Zhuo; Zhang Fei objects that he should have been allowed to do so earlier, while Guan Yu urges the party to gather their things and proceed. Their exchange gives the coalition’s large-scale mobilization a personal dimension: Xuande’s commitment is expressed as a direct desire to confront the tyrant, while the brothers bring their own history and urgency into the campaign.

The leaders choose Yuan Shao to command the expedition. After sacrifices, he vows before Heaven, Earth, and the ancestors that those assembled will protect the imperial family and its shrines from Dong Zhuo’s deeds. Yuan Shao assigns responsibility for supplies to his brother Yuan Shu. Sun Jian offers to lead the advance toward the pass, and the other leaders accept. The arrangements establish both a symbolic purpose and practical roles: Yuan Shao supplies the coalition’s recognized leadership, Yuan Shu is charged with provisions, and Sun Jian takes the forward position.

The Alliance Begins to Fracture

News of the coalition reaches the capital. Dong Zhuo pays little attention, but his adviser Li Ru takes the threat seriously and summons a council. Dong Zhuo’s adopted son, Lü Bu, offers to deal with the assembled forces, while Hua Xiong dismisses the danger and is sent that night with fifty thousand troops to stop them at the pass. These preparations show that the coalition has forced the regime to respond, even as Dong Zhuo himself remains indifferent.

The alliance’s deeper weakness appears after Sun Jian finds the Imperial Seal. When he says he will plead illness and leave, Yuan Shao confronts him with the accusation that his real ailment is possession of the Seal. Sun Jian neither admits finding it nor yields to Yuan Shao’s efforts to detain or persuade him. Offended and alarmed, he rides south with his entire army. A contest over a symbol of imperial authority thus undermines the coalition’s stated purpose of defending the imperial family: the leaders’ shared opposition to Dong Zhuo cannot contain their separate claims and suspicions.

Sun Jian’s departure is followed by Cao Cao’s withdrawal with his troops toward Yangzhou. Gongsun Zan and Xuande also leave Yuan Shao’s gathering, unconvinced that he has prospects. Passing through Pingyuan, Gongsun Zan asks Xuande to stay and defend the area. The coalition has not simply lost one contingent; its members are dispersing into separate regional positions, and Xuande’s next responsibility arises from that fragmentation.

Significance and Later Political Echoes

The coalition’s short-lived unity prefigures the novel’s wider account of the Han’s disintegration. The book presents three powers—those of Xuande, Cao Cao, and Sun Quan—as emerging from the weakening empire, with each leader carving out a kingdom from the Han’s decline. The coalition scene makes that larger transformation visible at an early stage: forces can unite against a common danger, but their leaders’ independent ambitions and political interests quickly pull them apart.

Later arguments about legitimacy give the alliance’s original vow a longer resonance. Kong Ming tells Xuande that Cao Cao controls the emperor and commands the allegiance attached to that authority; after Cao Pi takes the throne from the Han, Kong Ming urges Xuande to continue the Han line by becoming emperor himself. The coalition’s vow to protect the imperial family and its shrines therefore stands in contrast to the later struggle over who may claim the authority of the Han. The alliance begins with a language of collective loyalty, but the story that follows repeatedly tests that language against the competing claims of military power, dynastic descent, and Heaven’s mandate.

Historical and Narrative Frame

The novel’s account of the coalition belongs to a larger method that combines historical events with dramatic retelling. Its historical framework rests on events recorded in official histories, while oral storytelling, folk plays, and operas supplied dramatic patterns and memorable scenes; the novelist brought those layers together. The coalition’s pledged purpose, the personal confrontation over the Seal, and the dispersal of its members make political fragmentation legible as human conflict rather than as a bare succession of campaigns.

The episode also helps establish the recurring contrast between declared principle and political reality. The coalition gathers beneath Cao Cao’s banner of “Loyalty” and “Integrity” and vows to protect the Han, yet its members’ trust cannot survive the Seal dispute. Its failure is not an incidental pause in the campaign: it is an early demonstration that opposition to a common enemy does not itself create lasting allegiance, and that the empire’s defenders are already becoming competitors for authority.
