Juqu Mujian
In 439, Emperor Taiwu conquered Northern Liang, and took Juqu Mujian as a captive to the Northern Wei capital Pingcheng (平城, in modern Datong, Shanxi), but because of Princess Wuwei's sake, continued to honor Juqu Mujian as a brother-in-law with the title Prince of Hexi. During the marriage, Princess Wuwei bore Juqu Mujian a daughter, but no sons. In 447, Emperor Taiwu suspected Juqu Mujian of planning a rebellion and forced him to commit suicide, but buried him with honors. Princess Wuwei survived her husband, and later after her death was buried with her husband. (Some historical records indicate that she married Li Gai (李蓋) the Duke of Nan Commandery, but these are not conclusive.) Her daughter inherited her title as Princess Wuwei.
