Jiang Wei (202 – 3 March 264), courtesy name Boyue, was a military general of the state of Shu during the Three Kingdoms period of China. Born in Ji County (present-day Gangu County, Gansu), Jiang Wei started his career as a military officer in his native Tianshui Commandery, which was a territory of Wei. In 228, when Wei's rival state Shu launched an invasion led by Zhuge Liang, Jiang Wei was distrusted by Ma Zun, then administrator of Tianshui Commandery. As such, Jiang Wei had to defect to Shu. Zhuge Liang, the Imperial Chancellor and regent of Shu, highly regarded Jiang Wei and appointed him as a general in Shu. After Zhuge Liang's death in 234, Jiang Wei continued serving as a military commander during the regencies Jiang Wan and Fei Yi, eventually rising to the highest military rank
