In fall 508, Xuanwu's younger brother Yuan Yu (元愉) the Prince of Jingzhao, who had just been demoted by Xuanwu for corruption, became angry at both his demotion and that his favorite consort Lady Li had been severely battered by Empress Yu briefly before Empress Yu's death (because Yuan Yu's wife was Empress Yu's sister but was unfavored by him), declared a rebellion at his provincial post of Xindu (信都, in modern Hengshui, Hebei) and proclaimed himself emperor. Gao Zhao used this opportunity to falsely accuse Yuan Xie of acting in concert with both Yuan Yu (because Yuan Yu had forced Yuan Xie's uncle Pan Senggu (潘僧固) into joining his rebellion) and Liang Dynasty. Xuanwu believed Gao, and forced Yuan Xie to commit suicide. The populace and the officials greatly mourned Yuan Xie's death, and grew increasingly resentful of Gao. Soon, Yuan Yu's rebellion was defeated, and while Xuanwu contemplated not putting Yuan Yu to death, Yuan Yu was killed on Gao's orders.
