石敬瑭
In 936, Shi Jingtang rose in rebellion against then-Later Tang emperor Li Congke (Li Siyuan's adoptive son and Shi Jingtang's brother-in-law). As a result, a number of Shi Jingtang's relatives, including two sons, were executed by Li Congke. (The two sons were recorded in the "New History of the Five Dynasties" as Shi Chongying () and Shi Chongyin (), and in the "Zizhi Tongjian" as Shi Chongyin () and Shi Chongyi ().) During the subsequent siege of Taiyuan by the Later Tang general Zhang Jingda, Shi Chonggui personally helped to guard Shi Jingtang. Subsequently, a relief army from Khitan Empire's Emperor Taizong came to Shi Jingtang's aid and crushed Zhang's army, allowing the siege on Taiyuan to be lifted. Emperor Taizong subsequently declared Shi Jingtang to be the emperor of central China (as the founder of a new state of Later Jin).
