Gongsun Hong (公孫弘; Wade–Giles: Kung-sun Hung; 200 – 121 BCE) was a Chinese philosopher and politician in the Western Han dynasty under Emperor Wu. Together with the more famous Confucian scholar Dong Zhongshu, Gongsun was one of the earliest proponents of Confucianism, setting in motion its emergence under the Han court. The ideals both promoted, together with Gongsun's decrees, would come to be seen as values-in-themselves, becoming the "basic elements, or even hallmarks" of Confucianism. While first proposed and more ardently promoted by Dong, the national academy (then considered radical) and Imperial examination did not come into existence until they were supported by the more successful Gongsun. Their establishment set a precedent that would last into the twentieth century.
