After the successful campaign of AD 89, the Xiongnu state was destroyed. After the battle, Dou Xian led his forces back, and the "Northern Chanyu", whose name has not survived, sought to negotiate peace. Tuntuhe Chanyu of the Southern Xiongnu, however, was anxious to destroy his rival completely, and early in AD 90, as embassies were still being exchanged, Dou Xian launched an attack, captured his rival's seal and treasure and his wives and daughters.
