元曄
In 530, Emperor Xiaozhuang, apprehensive that Erzhu Rong would one day seize the throne, ambushed him in the palace at Luoyang and killed him and Yuan Tianmu. Erzhu Rong's wife Princess Beixiang and cousin Erzhu Shilong fought their way out of Luoyang and initially battled with Emperor Xiaozhuang's troops outside of Luoyang, but eventually withdrew north across the Yellow River. Erzhu Zhao met them at Zhangzi (長子, in modern Changzhi, Shanxi), and they jointly declared Princess Beixiang's nephew Yuan Ye the Prince of Changguang, a distant member of the imperial Yuan clan, emperor, to compete with Emperor Xiaozhuang.
