Gao Zhao
She was the daughter of Gao Yan (高偃), a younger brother of Emperor Xuanwu's mother Consort Gao Zhaorong (posthumously honored as Empress WenZhao), making them cousins. It is not clear when she became his concubine, but it was likely after he already had his first empress, Empress Yu, in 501. Once she became a consort, she was said to have gained his favor, and with her uncle Gao Zhao being a powerful official, it was believed, when Empress Yu died in 507, and Empress Yu's son Yuan Chang (元昌) died in 508, that she and/or Gao Zhao was involved, although there is no conclusive evidence. She was created empress in 508 to replace Empress Yu. She was said to be extremely jealous, and few imperial consorts were able to have sexual relations with the emperor. She herself bore him a son who died early, and a daughter, later created the Princess Jiande. In 510, however, Emperor Xuanwu's concubine Consort Hu bore him a son, Yuan Xu (元詡), and because Emperor Xuanwu had apparently lost sons before in addition to Yuan Chang and Empress Gao's son, he decided to raise his son by choosing wet nurses who had experience raising many of their own children, and refused to let either Empress Gao or Consort Hu near the child. In 512, Emperor Xuanwu created Yuan Xu crown prince.
