Empress Dowager Hu
In 528, with Empress Dowager Hu and Emperor Xiaoming in a conflict after Emperor Xiaoming wanted to put Empress Dowager Hu's lover Zheng Yan (鄭儼) to death by conspiring with the general Erzhu Rong, Empress Dowager Hu poisoned Emperor Xiaoming and put the young child Yuan Zhao, a great-grandson of Emperor Xiaowen from a collateral line, on the throne. Erzhu refused to recognize Yuan Zhao's imperial authority and advanced on Luoyang, quickly capturing it. He made Yuan Xie's son Yuan Ziyou emperor (as Emperor Xiaozhuang) and threw Empress Dowager Hu and Yuan Zhao into the Yellow River to drown.
