AD 263

AD 263 marks the final invasion of Shu Han and the approach of the Three Kingdoms period’s end. The Wei advance reached Chengdu that year, after which Liu Shan surrendered in 264–265, ending the Liu dynasty and bringing Shu Han into Wei. The episode completes a long contest over territory and imperial legitimacy, in which the Han’s collapse gives way first to rival kingdoms and ultimately to reunification.

A year of renewed conflict

The year’s military crisis grew out of Jiang Wei’s continuing effort to attack Wei. In the winter of AD 263, he had rebuilt the stockades, assembled supplies, sent ships downriver in preparation, and summoned his army. The Shu court was divided over another campaign: Liu Shan and many councillors opposed it, while Jiang Wei argued that Kong Ming had made repeated attempts to conquer Wei and that this would be his own eighth. His general Liao Hua questioned the wisdom of continuing, citing Deng Ai’s ability and the exhaustion of the people. Jiang Wei nevertheless advanced, planning to target Taoyang while using a projected attack on the Qishan pass as a diversion.

The campaign turned against Shu before its intended plan could succeed. Xiahou Ba was sent against Taoyang, but the apparently empty city proved to be a trap; he and nearly all his men were lost. Deng Ai then launched a night raid that threw Jiang Wei’s camp into disorder. Jiang Wei and Deng Ai continued to test one another over the following weeks, and Jiang Wei had begun to gain an advantage when repeated orders recalled him to the capital. Huang Hao had used his influence over Liu Shan to bring about the withdrawal, interrupting the campaign at a critical moment.

The advance on Chengdu

The Wei invasion that reached Chengdu in AD 263 followed a series of reversals for Shu. At Mianzhu, Zhuge Zhan and his son Zhuge Shang died fighting Deng Ai after an attempt to break out, and the city fell the next day. With that obstacle gone, the narrative turns sharply toward the capital: the march on Chengdu makes the survival of Shu an immediate question rather than a distant prospect.

The events at Chengdu belong to a much longer cycle of political division. The novel presents the Han’s collapse as the opening of a struggle among three leaders—Xuande, Cao Cao, and Sun Quan—whose competing states rose from the failing Han empire. Xuande’s claim rests on his descent from the House of Han and his stated desire to restore just rule; his advisers also urge him to accept the throne as an answer to the usurpation of Han authority. By contrast, the founding of Wei is represented as the result of Cao Pi’s succession to power after the Han emperor’s abdication. The arrival of Wei forces at Chengdu therefore brings the two rival claims into direct contact with the political fate of Shu.

Surrender and dynastic change

The invasion reached Chengdu in AD 263, but Shu Han’s surrender came in 264–265, when Liu Shan yielded to Deng Ai. This capitulation ended the Liu dynasty established by Xuande and concluded the Three Kingdoms period. Shu’s fall thus has both a military consequence—the loss of its capital and independence—and a dynastic one: the ruling house that had claimed to continue the Han came to an end.

The novel’s wider account frames such transitions through competing arguments about rightful rule. When the Han emperor transferred authority to Cao Pi, the abdication was presented as following the precedent of Yao and as recognition that the era of Han rule had ended. Xuande’s officials, in turn, argued that Cao Pi had usurped the throne and that Xuande should continue the Han line. These claims make the fall of Chengdu more than the outcome of a campaign: it closes one of the principal political alternatives created by the Han’s collapse.

From the Three Kingdoms to reunification

Shu’s surrender reunited it with Wei, ending the Three Kingdoms period. That settlement did not establish the final dynasty of the book’s chronology: from 265 to 280, China was ruled by the Jin dynasty of the Sima clan. AD 263 is therefore a threshold year rather than the date of complete reunification. The invasion reached its immediate objective at Chengdu, while the surrender and the subsequent transfer of power unfolded across the next two years.

The novel’s historical structure places this ending within a recurring pattern of empire, fragmentation, and reunion. Its account draws on historical events but shapes them into an epic of rulers, advisers, battles, and competing claims, while anonymous poems and traditions of storytelling help give the events a dramatic, memorable form. The fall of Shu completes the Three Kingdoms division in the narrative, yet the later rise of Jin underscores that the end of one conflict does not itself settle who will rule China.
