李渊
After the death of Emperor Yang of Sui in 618, Du Fuwei initially contended for supremacy of the lower Yangtze River region with fellow rebel leader Li Zitong the Emperor of Wu and the former Sui officials Shen Faxing the Prince of Liang and Chen Leng (), but after he was defeated by Li in 619, he submitted to Tang Dynasty. Emperor Gaozu of Tang (Li Yuan) commissioned Du as the commandant of the region, and in summer 620, Emperor Gaozu created Du the Prince of Wu, bestowed on him the imperial surname of Li, and made him the head of the branch imperial government for the region, while creating Fu Gongshi the Duke of Shu and making him Du's deputy.
