Liu Shan

Liu Shan is Liu Bei’s son and successor, and his accession makes him the second ruler of Shu Han. His early role is defined by the transfer of authority after Liu Bei’s death and by the immediate pressure of a five-army threat from Wei: anxious at the prospect of invasion, he turns to Zhuge Liang, who has prepared defenses and political countermeasures in advance.

Heir to the Han line

Liu Shan is named heir apparent when Liu Bei takes the imperial title in Shu. The proclamation raises the ruler’s family to imperial status, making his son the designated successor within the renewed Han lineage. The succession thus carries a political claim as well as a family inheritance: Liu Bei’s court presents its new reign as a continuation of the Han against Cao Pi’s seizure of the throne in Wei.

Liu Bei’s death makes that succession immediate. His body is carried to Chengdu, where the formal mourning rites and enthronement of Liu Shan take place, so the Han line in Shu can continue without interruption. Liu Bei is posthumously named August Emperor Zhao Lie and buried at Huiling; Liu Shan’s enthronement follows as the public and dynastic consequence of his father’s death.

A new ruler under pressure

The new reign begins amid reports that Cao Pi is preparing to attack Shu. Sima Yi has proposed a five-pronged plan intended to force Zhuge Liang to defend several fronts at once. Its proposed forces include troops recruited from the East Liao region, the southern Man people, Wu, Meng Da’s command, and Cao Zhen’s regular army. The plan makes Liu Shan’s early rule a test of whether the new court can withstand coordinated pressure from outside.

When reports of the mobilization reach him, Liu Shan is profoundly alarmed. He sends messengers to summon Zhuge Liang, but the prime minister does not appear. Officials sent on the following day also return without him; on the third day they wait in vain. With the threat still pressing and his chief adviser absent, Liu Shan goes to Zhuge Liang himself. This sequence presents him as a ruler who seeks guidance in an emergency, while also showing the anxiety created by the apparent unavailability of the person on whom the state depends.

Zhuge Liang’s reassurance and preparations

Liu Shan finds Zhuge Liang standing by a fishpond, leaning on a walking stick. When the ruler gently reproaches him for not helping at such a critical moment, Zhuge Liang answers that he already knows about the five armies and has arranged defenses against them. The encounter turns Liu Shan’s alarm into an opportunity for Zhuge Liang to explain how the danger has been addressed before the court fully understood it.

Zhuge Liang says that Ma Chao has been sent to secure Xiping Pass, where his standing among the Qiang makes an attack unlikely. Against the Man force, movement by the opposing army has confused the invaders and discouraged an assault. Zhuge Liang has also used a deception involving Meng Da: Meng believes that his friend Li Yan has asked him to pretend to be ill rather than assist Cao Pi. At Yangping Pass, Zhao Zilong is already in position, with Zhang Bao and Guan Xing each sent with thirty thousand troops to reinforce the defense.

The Wu front is different. Zhuge Liang reasons that Sun Quan will not attack while the other fronts remain inactive, but sees a need to send someone to persuade him that alliance with Shu serves his interests. This final measure shows that the response to the invasion is not purely military: it combines defense at strategic passes, deception, and an effort to prevent a hostile coalition from forming.

Succession and the limits of Liu Shan’s role

Liu Shan’s place in the narrative links dynastic continuity to political vulnerability. His enthronement prevents a break in the Han lineage claimed by Liu Bei’s Shu court, yet the danger of Cao Pi’s invasion arrives almost at once. The account gives Liu Shan a decisive action in the crisis—he seeks Zhuge Liang out after repeated summons fail—but the detailed plans belong to the prime minister and the commanders carrying them out.

That contrast establishes the shape of Liu Shan’s early reign in the material presented here: the new ruler inherits the title and the emergency together, while the survival of the state depends on Zhuge Liang’s prior arrangements and on the military and diplomatic network supporting them. Liu Shan’s alarm is therefore not the end of the episode but its turning point, bringing the ruler face to face with the preparations that have already begun to protect Shu Han.
