Emperor Ai of Tang
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
Yang Wu
Yang Xingmi died in 905 and was succeeded by his oldest son Yang Wo. In 907 Zhu Wen forced the last Tang emperor to abdicate and proclaimed himself the first emperor of the Later Liang. Yang Wo refused to acknowledge this change and continued the use of the last reign name of Tang. From this point Wu was an independent, sovereign entity.
