Born to Gao Gong in Chenliu Commandery, Gao Gan was a nephew of Yuan Shao. He played an instrumental role in convincing Han Fu to hand over Ji Province to Yuan Shao in 191. As reward, Yuan Shao made Gao Gan Governor of Bing Province. In 202, Gao Gan joined the Southern Xiongnu chanyu Huchuquan in attacking Hedong Commandery. They were defeated and Huchuquan surrendered to Cao Cao's officer Zhong Yao. Gao Gan surrendered to Cao Cao in 204 but felt unsatisfied with his new position as Inspector of Bing Province. In 205, Gao Gao seized Shangdang Commandery and invaded Hedong Commandery. Gao Gan failed to take Ye and was driven back. In 206, Cao Cao personally led an attack on Gao Gao, forcing him to flee to the Xiongnu and then to the south in Jing Province, where he was captured and killed.
