Yan Ding

Yan Ding, courtesy name Taichen, was a military general of the Jin dynasty (266–420). At the time of the Disaster of Yongjia in 311, Yan Ding brought the nephew of Emperor Huai, Sima Ye, to Chang'an, where a group of loyalists from Anding (安定, present-day Zhenyuan, Gansu) were in the process of retaking the region from Han-Zhao forces. After the re-establishment of the Jin government, Yan Ding became a powerful member of the new regime but jealousy and suspicion would cut his career short as his peers Qu Yun and Suo Chen combined their forces to have him killed.
