Yuan Ye
Empress Erzhu was the daughter of Erzhu Zhao, the nephew of Northern Wei's paramount general Erzhu Rong. In 530, Emperor Xiaozhuang, suspecting Erzhu Rong of plotting a coup, ambushed and killed him, and Erzhu Rong's relatives rose in rebellion. They declared Yuan Ye the Prince of Changguang, a distant member of the imperial clan, emperor, probably because Yuan Ye's aunt was Erzhu Rong's wife the Princess Beixiang. It is not known whether Empress Erzhu was already married to Yuan Ye by this point, but in any case he created her empress. In 531, after the Erzhus had defeated and killed Emperor Xiaozhuang, they concluded that Yuan Ye was too distant from the lineage of recent emperors, being the grandson of Emperor Wencheng's brother Yuan Zhen (元禎) the Prince of Nan'an, and they deposed him and replaced him with Yuan Gong the Prince of Guangling, who took the throne as Emperor Jiemin. During the reign of Emperor Jiemin, Yuan Ye was treated with respect and created the Prince of Donghai, so Empress Erzhu presumably would have carried the title of Princess of Donghai. However, Yuan Ye was subsequently forced to commit suicide in 532 after Emperor Jiemin and the Erzhus were overthrown by a coalition led by the general Gao Huan and replaced with Emperor Xiaowu.
