Juqu Mengxun
Juqu Mengxun (Chinese: 沮渠蒙遜; 368–433), also known by his posthumous name as the Prince Wuxuan of Northern Liang (北涼武宣王), was the second prince of the Lushuihu-led Chinese Northern Liang dynasty, and the first from the Juqu clan. His cousin Juqu Nancheng (沮渠男成) and he initially supported Duan Ye as prince of Northern Liang in 397 after rebelling against the Later Liang dynasty, but in 401, Juqu Mengxun tricked Duan Ye into wrongly executing Juqu Nancheng, and then used that as an excuse to attack and kill Duan Ye, taking over the throne himself.
