The state of Wu is the southern power in the Three Kingdoms, one of three kingdoms that rise from the disintegration of Han China. Its political identity rests on a durable regional base and the rule of Sun Quan’s family, but its position is never simply that of an isolated rival: Wu’s leaders weigh resistance to Cao Cao against the possibility of alliance with Xuande, even as disputes over territory strain relations between the southern court and Xuande’s growing power.

Emergence and Regional Foundations

The book frames the Three Kingdoms as the result of China’s collapse into warlord rule. Three leaders eventually carve kingdoms from the failing Han Empire: Xuande, Cao Cao, and Sun Quan. Wu is thus not merely a place-name but one of the three political centers through which the novel gives shape to a divided empire, each founded by a different leader and claiming a share of the land left by the Han.

Wu’s southern base has a history older than Sun Quan’s immediate rule. In Kong Ming’s assessment, Sun Quan’s family has governed south of the river for three generations. That continuity gives the regime an established local footing, while its strength is reinforced by popular support. Kong Ming therefore advises Xuande to regard Sun Quan as a potential ally rather than an enemy, a judgment that treats Wu’s political legitimacy and regional support as strategic assets as well as facts of government.

The contrast with Cao Cao is central to this assessment. Cao Cao commands a vast army, controls the emperor, and can draw nobles to his side; Sun Quan’s power is described as less formidable in raw terms, but rooted in the people of the south. Wu’s strategic importance consequently lies not only in its capacity to fight but in the independent base from which it can choose whether to resist, cooperate, or contest its neighbors.

Alliance and Strategic Competition

The danger posed by Cao Cao creates the immediate basis for cooperation between Wu and Xuande. As Zhou Yu considers the coming struggle, he recognizes that Kong Ming understands both strategy and Sun Quan’s mind, and fears that this insight could become a threat to his own position. Lu Su counsels against trying to eliminate Kong Ming while the conflict with Cao Cao remains unresolved. Instead, he proposes asking Kong Ming’s brother, Zhuge Jin, to persuade him to leave Xuande and serve Sun Quan. The episode shows how the alliance is made within a world of calculation: shared danger requires cooperation, but Wu’s officers still seek to draw talent into their own service and guard their own standing.

The Wu leadership’s deliberations also turn on the practical question of military strength. Zhou Yu argues that the northern army’s reputed million men include around 150,000 of Cao Cao’s own northern troops, exhausted by campaigning, and about 80,000 formerly serving Yuan Shao who have been conscripted and lack commitment to Cao Cao. He believes that 50,000 men can defeat them. Sun Quan, reassured by this analysis, declares himself ready to begin the war and, if necessary, face Cao Cao personally. Wu’s decision to resist is thus supported not by a denial of Cao Cao’s apparent superiority, but by a closer assessment of the composition and morale of his forces.

The narrative also marks an ethical condition on Wu’s military preparations: Zhou Yu orders his officers not to harm ordinary people as they move to their positions at the Three Rivers. The instruction places the protection of civilians alongside the regime’s military objectives, giving the preparations a stated limit even as war becomes imminent.

Jingzhou and the Fraying Partnership

Cooperation with Xuande does not settle the question of territory. After Xuande’s forces take Nanjun and Xiangyang, Zhou Yu is so distressed that his wound reopens and he collapses. He declares that only Kong Ming’s death will satisfy him and later tries to persuade Lu Su to join an attack on Xuande and Kong Ming. Lu Su refuses outright. Zhou Yu then accepts a less confrontational course, sending Lu Su as an ambassador to try to repair relations between the two leaders.

At Kong Ming’s headquarters in Gong’an, Lu Su is impressed by Kong Ming’s abilities and by the appearance of his army. He nevertheless presents Wu’s position: Xuande and Kong Ming have taken land belonging to the south and have no right to keep it. Kong Ming is surprised by the accusation. The encounter makes the alliance’s instability explicit: the same leaders who need one another against Cao Cao now disagree over whether Xuande’s territorial expansion is legitimate. Wu’s claim to Jingzhou is therefore not a passing grievance but a test of the partnership’s terms.

The strategic relationship carries personal and political tensions as well. After Zhou Yu dies, Kong Ming goes to pay his respects, guarded by Zhao Zilong and five hundred warriors because he faces plots against him. His eulogy praises Zhou Yu’s virtue, his friendship with Sun Ce, his role in creating Wu, his support for Sun Quan, and his resistance to Cao Cao. Those present are astonished, and Lu Su judges Kong Ming the larger person. Yet another observer accuses him of having driven Zhou Yu to his death and treats the public mourning as an insult to Wu. The scene leaves Wu’s political rivalry entangled with competing interpretations of Zhou Yu’s legacy: for Kong Ming, an occasion to honor a formidable opponent; for his critic, an occasion exposing the absence of comparable talent in Wu.

Succession, Legitimacy, and the Wider Order

Wu’s place in the story is set against the question of who may claim the authority once held by the Han. When Cao Pi receives an abdication announcement written in Emperor Xian’s name, it says that the Han era has ended and fortune has moved to the Cao family. The announcement invokes Heaven’s signs, the people’s sentiments, and the precedent of Yao’s abdication to present the transfer as legitimate rather than as seizure. Cao Pi accepts the throne, and the former emperor is reduced to the governorship of Shanyang.

The news reaches Xuande in Chengdu alongside rumors that the former emperor has been killed. Distressed by the reports, Xuande gives Kong Ming responsibility for day-to-day government. Kong Ming proposes that Xuande become emperor of Han, continuing the lineage as a descendant of the Han founder and opposing Cao Pi’s new title. Xuande initially recoils from what he sees as a rebellious and disloyal act; Kong Ming argues that Cao Pi has already usurped the throne and that Xuande has a duty to restore the Han. This contest over legitimacy clarifies the larger political setting in which Wu operates: the struggle among the kingdoms is also a struggle over the meaning of succession, dynastic continuity, and rightful rule.

Against that background, Wu’s identity is defined by both independence and interdependence. Its three-generation southern rule and popular support distinguish it from Cao Cao’s imperial control in the north, while its need to coordinate with Xuande makes alliance essential. But the dispute over Jingzhou shows how quickly shared resistance can give way to rival claims, and the contest over the Han’s successor places both cooperation and conflict within a larger crisis of political legitimacy.
