Liu Bei’s accession as emperor establishes Shu Han as a rival claimant to the Han legacy after Cao Pi has taken the throne and the Han emperor has abdicated. Its central conflict is not simply whether Liu Bei will accept imperial power, but whether claiming it can be presented as loyalty rather than usurpation: he resists the crown, while Zhuge Liang insists that restoring the Han requires him to rule.

Causes and competing claims

The immediate background is the end of the Han imperial line. In Cao Pi’s name, the former emperor’s abdication announcement declares that Heaven’s signs and the people’s wishes show that the Han era has ended and fortune has passed to the Cao family. The proclamation invokes the ancient example of Yao, who did not favor his own son, and casts the transfer of power as an act that serves the empire rather than one family. Cao Pi receives the jade seal and becomes emperor of Wei; the former emperor is reduced to the governorship of Shanyang.

News of Wei’s emergence, including rumors that the former emperor has been killed, weighs on Liu Bei in Chengdu, and he delegates day-to-day administration to Zhuge Liang. Zhuge Liang proposes that Liu Bei become emperor in order to oppose the new Wei ruler and continue the Han lineage. Liu Bei’s descent from the House of Liu lends the proposal a dynastic basis, but he is horrified by it. He calls the action rebellious and disloyal, and says that taking the throne would make him resemble a traitor. His objection is therefore also a crisis of political language: the same accession can be framed as illegitimate seizure or as a duty to restore a dispossessed dynasty.

Zhuge Liang answers by distinguishing Liu Bei’s position from Cao Pi’s. Cao Pi, he argues, has usurped the Han throne; Liu Bei, as a scion of the House of Liu, has a proper duty to take power back. After Liu Bei refuses again, Zhuge Liang warns that failing to act will mean failing to avenge the former emperor and disappointing those who want Liu Bei to rule. The officials’ case joins ancestry to responsibility: Liu Bei’s claim is not presented as private ambition, but as the necessary means of protecting the Han’s surviving lineage and answering the hopes of the people.

Zhuge Liang’s staged appeal

When argument does not persuade Liu Bei, Zhuge Liang goes home and announces that he is seriously ill. Liu Bei promptly visits him. Zhuge Liang explains that his distress comes from Liu Bei’s refusal: after Liu Bei trusted him and gained control of Shu, Cao Pi has now displaced the Han, yet the court’s appeals have been rejected. Unless Liu Bei accepts power, Zhuge Liang says, the court will lose hope and disperse, leaving Shu exposed to Wei and Wu.

Liu Bei maintains that his refusal is genuine and that he fears history’s judgment if he usurps the throne. Zhuge Liang counters that refusing Heaven’s will carries its own danger. Liu Bei finally agrees, but postpones action until Zhuge Liang has recovered. At that moment Zhuge Liang rises from his sickbed and reveals that court officials and commanders have been listening behind a screen. They prostrate themselves and immediately ask to choose the coronation day. Liu Bei recognizes that Zhuge Liang has tricked him and calls the maneuver disreputable; Zhuge Liang replies that Liu Bei has consented and that preparations must proceed. The scene turns a private, reluctant assent into a public commitment witnessed and enforced by the court.

Accession and the claim to legitimacy

The proclamation issued in Liu Bei’s name describes him as preserving the unbroken Han lineage against the actions of Cao Cao and Cao Pi. It says that no one else can take up the Han cause, that Liu Bei has sought the judgment of all, and that Heaven’s Mandate cannot be ignored even though he approaches the decision with fear. The official account thus recasts a contested transfer of power as an obligation accepted reluctantly for the sake of the dynasty and the realm.

Liu Bei takes the jade seal of authority after making three further attempts to refuse. The repeated refusals sustain the appearance that he is not pursuing the crown for personal gain, while the proclamation’s appeal to Heaven, collective consent, and Han descent supplies grounds for his rule. The contrast with Cao Pi’s accession is central: both successions are staged through imperial ritual and the language of abdication, but Liu Bei’s case rests on continuing the Han line, whereas the prior announcement says that the Han Mandate has passed to the Cao family.

The new court and its immediate consequence

The accession changes the status of Liu Bei’s household and government. His family is elevated to imperial rank, his son Shan is named heir apparent, and Zhuge Liang becomes prime minister. The news is greeted with rejoicing in Shu, marking the establishment of a court that claims not merely regional authority but the imperial inheritance of the Han.

The new title also gives immediate force to a different obligation. The next day, Liu Bei announces that the Peach Orchard oath binds him to avenge Guan Yu’s death by attacking Sun Quan. The declaration links the founding of the new reign to personal and sworn loyalty, and turns the accession from a settlement of dynastic legitimacy into the prelude to renewed war. Its significance lies in that double movement: Liu Bei accepts imperial authority as the means to continue the Han, then uses the authority of the new reign to pursue the oath-bound cause of vengeance.
