 In 528, Emperor Xiaoming was poisoned to death by his mother Empress Dowager Hu after trying to curb her power and trying to kill her lover Zheng Yan (鄭儼).Emperor Xiaoming was sonless, and while Empress Dowager Hu initially tried to pretend that Emperor Xiaoming's daughter, by his concubine Consort Pan, was actually a son, she soon realized that she could not carry on the deception, and she named Yuan Zhao emperor—selecting him due to his young age so that she could control him.The general Erzhu Rong, with whom Emperor Xiaoming had conspired against Empress Dowager Hu, refused to recognize Yuan Zhao as emperor, quickly descending on the capital Luoyang with his troops and declaring a son of Emperor Xiaowen's brother Yuan Xie, Yuan Ziyou, emperor (as Emperor Xiaozhuang).
