Life
editGongsun Yuan was a son of Gongsun Kang, a warlord who controlled Liaodong, Xuantu, Lelang and Daifang commanderies in the late Eastern Han dynasty. He became a vassal of the state of Cao Wei during the Three Kingdoms period. When Gongsun Kang died, his sons Gongsun Huang and Gongsun Yuan were still too young at the time to succeed him, so his younger brother Gongsun Gong took over. In 228, a grown-up Gongsun Yuan seized power from his uncle Gongsun Gong and imprisoned him.
Although Gongsun Yuan was nominally a vassal of the Cao Wei state, he considered switching allegiance to Wei's rival state, Eastern Wu. Gongsun Yuan eventually yielded under pressure from the Wei emperor Cao Rui. He killed the Wu delegates but some of them fled to Goguryeo. The Wu emperor Sun Quan attempted to form an alliance with Goguryeo to launch a pincer attack on Gongsun Yuan, but Goguryeo eventually sided with Wei against Gongsun Yuan.
In 237, the Wei emperor Cao Rui felt insecure about Gongsun Yuan's influence in the northeast, so he sent the general Guanqiu Jian to lead an army of Chinese, Wuhuan and Xianbei troops to attack Gongsun Yuan, but floods caused the campaign to be aborted. Gongsun Yuan declared himself "King of Yan" (燕) and concluded an alliance with Eastern Wu. The following year, the Wei generals Sima Yi and Guanqiu Jian led a campaign against Gongsun Yuan. Gongsun Yuan was defeated and killed while his clan was exterminated. As a consequence, Liaodong and present-day northwest Korea became Wei territories.

edit- ^ Cao Rui's biography in Sanguozhi indicated that Sima Yi laid siege to Xiangping on the bingyin day of the 8th month of the 2nd year of the Jing'chu era. However, there is no bingyin day in that month; the next bingyin day is in the 9th month of that year and corresponds to 3 Sep 238 in the Julian calendar. Volume 74 of Zizhi Tongjian placed the fall of Xiangping on the renwu day of the 8th month of that year. However, there is also no renwu day in that month; the next renwu day is also in the 9th month and corresponds to 19 Sep 238 in the Julian calendar.
