Gao Zhao
She was the daughter of Yu Jing (于勁), the younger brother of the powerful general Yu Lie (于烈). It was said that when Emperor Xuanwu first assumed imperial powers — which probably referred to his relieving his uncle Yuan Xie of authorities in 501 — Yu Lie believed that the emperor lacked sufficient consorts, and so persuaded Emperor Xuanwu's attendants to praise of her beauty and virtues. Emperor Xuanwu took her as an imperial consort, and in late 501 created her empress. She was said to be quiet, tolerant, and not jealous. She bore him one son, Yuan Chang (元昌), in 506. By that point, however, she was said to have lost his favor, as he favored his cousin Consort Gao, and their uncle Gao Zhao became exceedingly powerful. When Empress Yu suddenly died in 507, it was believed that Consort Gao poisoned her, but historians concede that there is not conclusive evidence. When her son Yuan Chang died the following year (508), it was also alleged that Gao Zhao had him poisoned.
