Lý Thiên Bảo (traditional Chinese: , pinyin: LàTiÃÂnbÃÂo) (499?-555) was the older brother of Lý Nam ÃÂế, who tried unsuccessfully to resist the forces of China's Liang dynasty.
In 548 Lý Nam ÃÂế had fallen ill while resisting the Liang dynasty forces led by Chen Baxian (founder of the Chen dynasty) in the Northwest Vietnam mountains. Lý Nam ÃÂế decided to relinquish his imperial authority and transferred his power to his older brother Thiên Bảo and trusted lieutenant Triá»Âu Quang Phục as co-rulers in his place with the intention of continuing the struggle against the Han.
In 555, Lý Thiên Bảo fell ill and died without leaving an heir, thus making Triá»Âu Quang Phục as sole ruler. Triá»Âu Quang Phục, better known as the emperor Triá»Âu Viá»Ât Vðáng, was able to consolidate the armed forces under Lý Thiên Bảo and Lý Nam ÃÂế against the Han invasion.
