Lǐ Xuánbà (李玄霸) (599 - 614),[1] courtesy name Dàdé (大德),[2] was the third son of Emperor Gaozu of Tang. His mother was Lady Dou. He died in 614 after being struck on the head by his own weapon.[3] After the establishment of the Tang dynasty, he was posthumously created Prince Huai of Wei. He died sonless, so Li Tai, son of his elder brother Li Shimin, was created his heir as Prince of Yingdu (宜都王) in 621. When Li Shimin became emperor, he re-designated Li Tai as his own son and created another clansman Li Baoding as heir to Li Xuanba. After Baoding also died sonless in 631, the Principality of Wei was cancelled.[4]
