Gao Zhao
During these years, Northern Wei and Liang continued to have relatively minor border battles, with each side having gains and losses. In 514, however, Xuanwu commissioned Gao Zhao to launch a major attack against Liang's Yi Province (modern Sichuan and Chongqing). Soon thereafter, however, in spring 515, he died suddenly, and Yuan Xu succeeded him (as Emperor Xiaoming). Yuan Cheng, Xuanwu's brother Yuan Yong the Prince of Gaoyang, and Yu Lie's son Yu Zhong seized power and, after recalling Gao, put him to death, and Gao was removed. Xiaoming's mother Hu became empress dowager and regent.
