李昪
On 12 March 939 Xu Gao took on the name of Li Bian. He additionally authorized a genealogy that claimed descent from the Tang Imperial family. Records vary about whom his supposed Tang progenitor was. Johannes L. Kurz concluded that the more reliable sources state his ancestor was either son or a younger brother of Xuanzong. On 2 May 939 Li Bian performed the traditional sacrifices to Heaven. Jingnan and Wuyue sent ambassadors praising this event.
