孟知祥
In 923, Li Cunxu declared himself the emperor of a new state of Later Tang (as Emperor Zhuangzong) at Xingtang (興唐, i.e., Weibo's capital). He designated Taiyuan as the western capital and made Meng Zhixiang its mayor, as well as its deputy defender. (Meng's wife, as the new emperor's eldest sister, was created the Grand Princess Qionghua, either at that time or in 925.) Shortly after, Emperor Zhuangzong destroyed rival Later Liang and took over its territory, setting his capital at Luoyang.
