Gao Zhao
In the winter of 515, Emperor Xuanwu wanted to try to capture rival Liang's Yi Province (modern Sichuan and Chongqing), and he commissioned Gao Zhao as the commander of the expedition force. Soon after Gao Zhao left the capital Luoyang, however, Emperor Xuanwu died of a sudden illness in spring 515. Emperor Xuanwu's crown prince Yuan Xu (元詡), then age five, succeeded him (as Emperor Xiaoming). In the confusion of the events, Empress Gao tried to have Emperor Xiaoming's mother Consort Hu killed, but could not. Meanwhile, the official Yu Zhong and the imperial princes (Emperor Xuanwu's uncles) Yuan Cheng (元澄) the Prince of Rencheng and Yuan Yong the Prince of Gaoyang seized power, forcing Empress Gao, who was honored as empress dowager, to appoint Yuan Cheng and Yuan Yong as regents.
