Li Xun

Li Xun (李恂) (died 421), courtesy name Shiru (士如), was the final ruler of the Chinese state Western Liang, who tried to hold out against the conquering Northern Liang armies under its prince Juqu Mengxun, after his brother Li Xin's death in 420. He was only able to hold the city of Dunhuang (敦煌, in modern Dunhuang, Gansu) for several months, before Juqu Mengxun successfully sieged the city, and Li Xun committed suicide.
