Imperial Nanking University, the predecessor of Nanjing University, was founded in Nanjing (南京, Nankin, Nanking) in the first year of the Yong'an reign (258 CE) under the Kingdom of Wu by Sun Xiu, Emperor Jing of Wu. Its first president was scholar politican Wei Zhao (韋昭). The Imperial University in Nanking (南京太學, Nanking Taixue) was reestablished by Emperor Yuan of Jin (晋元帝/晉元帝) in the first year of Jianwu reign (317). 155 new rooms were built in the campus which was located in today's Fuzimiao (夫子廟) area of Nanjing situated on Qinhuai River banks, and the Nanking Imperial University began recruiting students from common families instead of only from families of high ranking officials. Like its forerunner Chengjun (成均) and succeeding Shang Hsiang (上庠) founded by the legendary Yu the Great (禹, 21st century BCE) in Chungyuan– the earliest recorded imperial higher learning institutions and their successors–it was the Kingdom's central university.
