Western Wei
Yuan Humo was the fifth daughter of Emperor Wen of Western Wei, and she carried the title Princess Jin'an during the reigns of her father and her brothers Emperor Fei of Western Wei and Emperor Gong of Western Wei. Sometime after Yuwen Jue, the son and heir of then-paramount general Yuwen Tai, was created the Duke of Lüeyang in 550, she married Yuwen Jue as his duchess. After Yuwen Tai died in 556, Yuwen Jue inherited his titles, under the guardianship of Yuwen Tai's nephew Yuwen Hu. In spring 557, Yuwen Hu forced Duchess Yuan's brother Emperor Gong to yield the throne to Yuwen Jue, ending Western Wei and establishing Northern Zhou. Emperor Xiaomin, then carrying the title of Heavenly Prince, created her as his princess.
