Huang Hao

Huang Hao ( 220s–263) was a Chinese eunuch and politician serving under Liu Shan (), the second and last emperor of the state of Shu Han in the Three Kingdoms period (220–280) of China. He gained the favour of Liu Shan and became highly influential.  He was able to promote his supporters and demote those who opposed him to the overall detriment of the good governance of the state.  When the leading Shu Han general Jiang Wei sought to warn the emperor that an invasion by Cao Wei was imminent, Huang Hao advised the emperor that such an invasion would not happen.  As a result, the Shu Han state was not prepared for the Wei invasion of Shu forcing the emperor to surrender unconditionally in 263.
