劉知遠
Liu Zhiyuan was military governor of Bingzhou, an area around Taiyuan in present-day Shanxi that had long been a stronghold of the sinicized Shatuo. However, the Later Jin he served was weak and little more than a puppet of the expanding Khitan empire to the north. When the Later Jin finally did decide to defy them, the Khitan sent an expedition south that resulted in the destruction of the Later Jin.
