Wei

Wei is the dynasty that succeeds the Han in the northern political order and becomes one of the three kingdoms dividing the empire. Its founding is presented as a transfer of the Mandate of Heaven from the Liu house to the Cao family, but the story makes that succession visibly unstable: the abdication is obtained through pressure and ceremony, a storm disrupts Cao Pi’s inaugural sacrifice, and Sun Quan’s later submission to Wei serves immediate strategy without preventing conflict.

Origins in the Han’s collapse

The Three Kingdoms take shape as the Han empire fragments and three leaders establish competing states: Liu Bei, called Xuande in the narrative, Cao Cao, and Sun Quan. Wei’s rise is tied especially to Cao Cao’s command of the imperial court. By the time Xuande seeks Kong Ming’s counsel, Cao Cao controls the emperor, commands an army described as exceeding a million, and possesses the political advantage that comes with the court’s allegiance. Kong Ming therefore judges him a power Xuande cannot directly oppose.

Wei’s founding also rests on an earlier claim that the Han’s authority has already run its course. When Xuande’s successes lead his commanders to urge him to become emperor, Kong Ming argues that Cao Cao has usurped the true ruler and that Xuande, known for benevolence and in control of Shu, should assume the throne. Xuande objects that doing so would make him appear a rebel, despite his descent from the Han house. The dispute establishes the central difficulty of Wei’s legitimacy: dynastic authority is not simply inherited or seized; it must be argued for in terms of ancestry, virtue, popular support, and Heaven’s will.

Signs and the transfer of the throne

In AD 220, court astrologers and high officials interpret a phoenix, a unicorn, and a yellow dragon as signs that the Han Mandate has ended and that Wei is to replace it. A delegation led by Hua Xin presents the former Han emperor, Emperor Xian, with a request to abdicate in favor of Cao Pi. The emperor recalls that the Liu family has ruled for four hundred years and asks what wrong he has committed to be made to surrender the inheritance of his ancestors. Hua Xin answers with astrologers who repeat the interpretation of the omens; when Emperor Xian rejects their reasoning, Wang Lang argues that dynasties and ruling families inevitably come to an end and urges him to yield peacefully.

The abdication is written in the emperor’s name and invokes both Heaven’s signs and the precedent of Yao, who is said not to have favored his own son. Its argument is that the empire belongs to all, not to one house, and that the Han era has ended while fortune has passed to the Cao family. Cao Pi is pleased to receive the announcement, but Sima Yi advises him to refuse at first. After further appeals, Sima Yi arranges for the emperor to order an Altar of Abdication, where the transfer can be made before assembled officials and soldiers.

At the altar, Emperor Xian hands over the Jade Seal of authority and Cao Pi accepts it, beginning his reign as emperor of Wei. The former emperor is reduced to the rank of governor of Shanyang and ordered to leave. The ceremony gives the transfer a formal shape and presents Wei as the recipient of the imperial mandate, while the staged refusals and the emperor’s earlier protest make clear how little room he has to choose otherwise.

Omens and contested legitimacy

The ceremony does not settle the question of Heaven’s approval. When Cao Pi kneels to worship Heaven and Earth, a violent storm breaks out. Wind scatters dust and stones, the sky darkens, and the altar’s ritual lanterns are blown over. The narrative identifies the storm as a portent of Heaven’s displeasure: Cao Pi collapses and is carried away, remaining unable to act for days. He does not recover his confidence and comes to believe that the palace itself is haunted, prompting him to begin construction of another palace at Luoyang.

This interruption contrasts with the official language of a mandate freely transferred according to ancient precedent. The omens that authorize Wei are interpreted by court officials, but the storm that follows the accession appears to challenge the new ruler’s claim. The story does not erase Wei’s successful seizure of the throne; instead, it places the new dynasty’s public legitimacy beside signs that complicate its moral and cosmic standing.

Relations with Shu and Wu

The emergence of Wei prompts a rival claim in Chengdu. Rumors about the former emperor’s fate, including that he has been killed, distress Xuande, who entrusts day-to-day affairs to Kong Ming. Kong Ming proposes that Xuande be crowned emperor of Han, continuing the Liu lineage in opposition to Cao Pi. Xuande initially regards the proposal as rebellious and disloyal. Kong Ming counters that Cao Pi has usurped the Han throne and that Xuande has a proper duty, as a descendant of the Liu house, to reclaim it. Wei’s founding therefore deepens rather than ends the contest over who can claim continuity with the Han.

Wei also becomes a possible partner and instrument in the rivalry between Shu and Wu. Facing the prospect of Shu’s invasion, Sun Quan accepts Zhao Zi’s proposal to submit to Cao Pi and seek Wei’s help to divert the Shu army toward Hanzhong. Cao Pi understands that the submission is designed to redirect the danger. He grants Sun Quan the title of king of the south, despite his adviser Liu Ye’s objection that Wu and Shu should be left to weaken each other, and sends official documents to formalize the arrangement.

The ceremony of submission is strained from the outset. Cao Pi’s envoy Xing Zhen rides into Wu’s capital in a manner that angers its officials, and a Wu commander protests that Wu should be destroying Shu and Wei rather than accepting a title. Sun Quan nevertheless submits and accepts the kingship. The concession does not stop the Shu invasion, and Wei provides no visible help as the threat reaches Wu’s borders. The episode shows Wei exercising the authority of an emperor through investiture while revealing how limited that authority is when a vassal’s immediate military interests point elsewhere.
