Jiang Wei

Biography & Historical Record

Jiang Wei (姜维, Khương Duy) was a prominent military general and regent of the state of Shu Han (蜀汉, Thục Hán) during the Three Kingdoms period of China. Originally a mid-level military officer serving the rival state of Cao Wei (曹魏, Tào Ngụy) in his home commandery of Tianshui, Jiang Wei’s destiny pivoted dramatically in 228 AD. During the first Northern Expedition of the Shu chancellor Zhuge Liang (诸葛亮, Gia Cát Lượng), Jiang Wei was suspected of disloyalty by his superior Ma Zun (马遵, Mã Tuân) and was locked out of his home city. With no recourse, he defected to Shu Han, where his exceptional talents were immediately recognized by Zhuge Liang.

Under Zhuge Liang’s mentorship, Jiang Wei rose rapidly through the ranks. He was highly regarded for his versatility, intellect, and profound understanding of military strategy. Following the deaths of Zhuge Liang (诸葛亮, Gia Cát Lượng), Jiang Wan (蒋琬, Tưởng Uyển), and Fei Yi (费祎, Phí Y), Jiang Wei eventually assumed supreme command of Shu Han’s military forces. Driven by an unyielding desire to fulfill Zhuge Liang’s legacy of restoring the Han Dynasty, he launched a series of eleven military campaigns (historically recognized as Jiang Wei’s Northern Expeditions) against Cao Wei between 247 and 262 AD.

Though Jiang Wei achieved notable tactical successes—most famously at the Battle of Didao in 255 AD where he decimated the Wei forces under Wang Jing (王经, Vương Kinh)—his campaigns ultimately failed to achieve a decisive breakthrough. His efforts were severely hampered by domestic political opposition, particularly from the cautious minister Fei Yi (费祎, Phí Y) during his early career, and later by the corrupt eunuch Huang Hao (黄皓, Hoàng Hạo), who enjoyed the favor of the weak-willed emperor Liu Shan (刘禅, Lưu Thiện). The endless military mobilization also placed a heavy economic strain on the domestic resources of Shu Han.

In 263 AD, Cao Wei launched a massive, multi-pronged invasion of Shu Han led by Zhong Hui (钟会, Chung Hội) and Deng Ai (邓艾, Đặng Ngải). Jiang Wei masterfully blocked Zhong Hui’s main army at the strategic bottleneck of Jiange. However, Deng Ai bypassed Jiang Wei’s defenses by executing a daring march through the treacherous Yinping mountain pass, appearing suddenly before the capital city of Chengdu. Emperor Liu Shan (刘禅, Lưu Thiện) surrendered without a fight, ordering Jiang Wei to capitulate to Zhong Hui.

Unwilling to let the Han state perish, Jiang Wei devised a final, desperate stratagem. He feigned surrender to Zhong Hui, assessed Zhong’s personal ambitions, and successfully incited him to rebel against the Wei regent Sima Zhao (司马昭, Tư Mã Chiêu). Jiang Wei’s ultimate plan was to help Zhong Hui seize power, assassinate him during the chaos, and restore Liu Shan (刘禅, Lưu Thiện) to the throne. However, the plot leaked, inciting a violent mutiny among the Wei soldiers in 264 AD. Both Zhong Hui and Jiang Wei were slain in the chaos, marking the tragic and definitive end of the Shu Han state.

Role in Romance of the Three Kingdoms

In La Guanzhong’s historical novel Romance of the Three Kingdoms, Jiang Wei (姜维, Khương Duy) is portrayed as a tragic hero of epic proportions, acting as the spiritual and military successor to Zhuge Liang (诸葛亮, Gia Cát Lượng). He is introduced in Chapter 92 as a brilliant young warrior-scholar of Cao Wei who successfully anticipates and thwarts Zhuge Liang’s initial tactical traps. Deeply impressed by Jiang Wei’s intellect and martial prowess, Zhuge Liang designs an elaborate scheme to capture and convert him to the Han cause.

Upon his defection, Jiang Wei is embraced by Zhuge Liang not merely as a general, but as a protégé. On his deathbed at Wuzhang Plains, Zhuge Liang bequeaths his lifelong work, the Twenty-Four Volumes of Military Strategy (兵法二十四篇), to Jiang Wei, symbolically passing the mantle of Han preservation to him. From this point forward, Jiang Wei is depicted as a lone colossus fighting against both the formidable external enemies of Cao Wei and the internal decay of the Shu Han court.

“My plan has failed; it is the will of Heaven!”

— Jiang Wei’s final lament before committing suicide in the mutiny of Chengdu.

The novel dramatizes his rivalry with the Wei general Deng Ai (邓艾, Đặng Ngải), turning their campaigns into a grand chess match of formations, weather strategies, and ambushes. Jiang Wei’s final attempt to resurrect Shu through Zhong Hui (钟会, Chung Hội) is painted as a masterstroke of desperate genius that fell agonizingly short due to cosmic fate. According to the novel, when the Wei soldiers cut open Jiang Wei’s body after his death, they discovered that his gallbladder was “as large as a hen’s egg” (胆大如斗), explaining his extraordinary and fearless courage.
