Jia Ya (died 312), courtesy name Yandu, was a Chinese military general of the Jin dynasty (266–420). He was most known for leading the empire's restoration movement against the state of Han Zhao in Anding (安定, present-day Zhenyuan, Gansu) following the Disaster of Yongjia in 311. However, his untimely death the next year undermined the potential of the group, as power would fall into the hands of Suo Chen and Qu Yun, who held on desperately to their influence on Emperor Min of Jin in Chang'an. His name can be rendered as Jia Pi. Life Jia Ya was from Wuwei Commandary in modern-day Gansu. His great-grandfather was the famed advisor of the warlord Cao Cao, Jia Xu who helped lay the foundation of the state of Cao Wei during the Three Kingdoms. In his youth, he was well-respected by the people for his talents and openness to them. He joined the Jin government, and rose to the rank of Administrator of Anding. Jia Ya was also involved in the War of the Eight Princes in 306, in which he sided with Sima Yue against Sima Yong and killed the generals Ma Zhan (馬瞻) and Liang Mai (梁邁). During the reign of Emperor Huai of Jin in 311, the Inspector of Yongzhou, Ding Chuo (丁綽) slandered Jia Ya to the Prince of Nanyang, Sima Mo (司馬模). Jia Ya was also hosting the rebel Pei Bao (裴苞), who had opposed Sima Mo. Jia Ya fled to the Lu River, where he befriended two tribal men named Peng Dangzhong (彭蕩仲) and Dou Shou (竇首). Together, they helped Jia Ya return to Anding, where they killed Sima Mo's general Xie Ban (謝班) and forced Ding Chuo to flee to Wudu. The emperor pardoned Jia Ya and appointed him the new Inspector of Yongzhou. Later that year, the forces of Han Zhao took over Luoyang and captured the emperor as well. Soon, Chang'an also capitulated after Sima Mo was captured and executed by Han. Jia Ya and many of the tribal leaders around Anding sent their officials' children over to Luoyang to submit to Han Zhao. However, they did not reach the capital, rather they were led home by Sima Mo's subordinates Suo Chen and Qu Yun, who were fleeing from Han Zhao forces. Suo Chen, Qu Yun and the others discussed plans to restore Jin's authority in the north, and they all agreed to
