Gongsun Kang
The Wuhuan, a people similar to the Xianbei, were a loose confederation of nomads that had been subservient to larger and stronger neighboring powers for most of their existence. In 168 the Wuhuan established some degree of independence under their own leaders. The largest of these groups were led by Nanlou in Shanggu, Qiuliju in Liaoxi, Supuyan in the Dependent State of Liaodong, and Wuyan in Youbeiping. In 187 Qiuliju joined the rebellion of Zhang Chun. Following the defeat of Zhang Chun in 188, Qiuliju attacked Gongsun Zan but was defeated. In 190 he surrendered to Liu Yu and died in 193. Qiuliju's son Louban was too young to succeed him so his cousin Tadun became acting guardian. In 195 Tadun, Nanlou and Supuyan supported Yuan Shao against Gongsun Zan. In 207 Tadun was defeated by Cao Cao at the Battle of White Wolf Mountain and died in battle. After their defeat many of the Wuhuan surrendered to Cao Cao and served as part of Cao Cao's cavalry forces. Louban and Supuyan fled to Gongsun Kang, who killed them.
