Liu Shan ruled Shu Han for 40 years, the longest reign of any Three Kingdoms emperor. His reign saw the Northern Expeditions under Zhuge Liang and later Jiang Wei, but also factional infighting and eventual decline leading to surrender.
Liu Shan surrendered the Shu Han kingdom to the invading Wei army under Deng Ai, ending the state founded by his father Liu Bei. The surrender occurred after the fall of Chengdu, and Liu Shan was taken to Luoyang as a captive.
