Emperor Xiaoming of Northern Wei

Emperor Xiaoming of (Northern) Wei ((北)魏孝明帝) (510 – March 31, 528), personal name Yuan Xu (元詡), was an emperor of the Xianbei-led Chinese Northern Wei dynasty. He ascended the throne in 515 at the age of five, and governmental matters were dominated by his mother Empress Dowager Hu (with an intervening regency by the official Yuan Cha from 520 to 525). In 528, Emperor Xiaoming tried to curb his mother's powers and kill her lover Zheng Yan (鄭儼) by conspiring with the general Erzhu Rong. As a result, the 18-year-old emperor was poisoned by his mother, who was soon overthrown by Erzhu. From that point on, Northern Wei royal lineage had no actual power. The next ruler, Emperor Xiaozhuang (507–531) was established by Erzhu. Since Erzhu's rival, general Gao Huan, enthroned another royal offspring, the country was soon split in two rival polities, Eastern and Western Wei, both of which did not hold long on the political map of the Southern and Northern Dynasties.
