唐明宗
Shortly after, Emperor Zhuangzong was killed in a mutiny at Luoyang itself. Li Siyuan thereafter arrived at Luoyang and took control of the city, initially only claiming the title of regent. Part of the orders he issued was to look for and welcome the imperial princes back to the palace. Two of Emperor Zhuangzong's biological brothers, Li Cunque () the Prince of Tong and Li Cunji () the Prince of Ya, were then hiding among the common people. Li Shaozhen and An located them, but instead of taking them back to the palace as Li Siyuan had instructed, they opined that Li Siyuan should next take the throne and that these imperial princes' presence would interfere with that plan, so they killed Li Cunque and Li Cunji without approval from Li Siyuan.
