Emperor Min surrendered in 316 to Liu Yao, a general of the Xiongnu state Han Zhao, and was later executed by , the emperor of Han Zhao, in 318.
Prior to becoming emperor
Sima Ye was a son of Sima Yan the Prince of Wu, a son of Jin's founding emperor . However, he was posthumously adopted by his uncle Sima Jian the Prince of Qin, who died in 291, nine years before his birth, and so he inherited the title of Prince of Qin.
When the Jin capital Luoyang fell to Han Zhao forces in 313, Prince Ye's uncle was captured, and his father Prince Yan was killed. Prince Ye himself, at age 13, was able to escape from Han Zhao forces, and he got to Mi when he encountered his uncles, the Jin officials Xun Fan and Xun Zu , who decided to support him as their leader. Later that year, the general Yan Ding tried to escort Prince Ye into the Guanzhong region , where he thought the central government could be rebuilt, but on the way, most of the supporters and troops deserted them -- including Prince Ye's uncles. Eventually, however, Yan and Prince Ye were able to arrive in Guanzhong. They were supported by the general Jia Pi , and Jia was able to capture Chang'an in 312, allowing Prince Ye to enter and set up his headquarters there. In fall 312, Jia and Yan offered Prince Ye the title of crown prince, and they then organized a provisional government.
In spring 313, the captured Emperor Huai was executed by the Han Zhao emperor . The news, however, took three months to get to Chang'an. Once it did, Crown Prince Ye held an official mourning for his uncle and then ascended the throne as Emperor Min. At that time, the city of Chang'an was so poor that it had less than a hundred households, and there were only four wagons available. The officials lacked official uniforms and seals. The military matters were largely entrusted to the generals Qu Yun and Suo Lin . Emperor Min issued an edict ordering Sima Bao the Prince of Nanyang, who still had a sizable force in Qin Province and the Prince of Langye, who held large portions of territory near and south of the Yangtze River, to come to his aid, but both Sima Bao and Sima Rui only paid nominal allegiance to him and failed to actually provide any assistance. Around the new year of 314, Han Zhao made a surprise attack on Chang'an, and while that attack was thwarted that time, it showed how the Jin regime under Emperor Min lacked power to defend itself. Only Zhang Gui the governor of Liang Province sent small detachments and supplies periodically to Chang'an. In 315, Sima Bao considered coming to Emperor Min's aid, but ultimately did not do so, and Suo subsequently refused a plan to send the emperor to Sima Bao, reasoning that Sima Bao would then use the emperor as a puppet.
In fall 316, the Han Zhao general Liu Yao the Prince of Zhongshan made a major attack against Emperor Min's territory. After he captured Beidi Commandery , the other Jin cities in Guanzhong collapsed. Two relief forces arrived, but were hesitant to engage Liu Yao. Liu Yao therefore was able to siege Chang'an, and after the food supply ran out, Emperor Min resolved to surrender. He was delivered by Liu Yao to the Han Zhao capital Pingyang .
After capture by Han Zhao
Liu Cong initially created the former Jin emperor the Marquess of Huai'an. In early 318, at a feast, he had the marquess serve as butler, and a number of former Jin officials could not control themselves and cried outloud at their former emperor's humiliation. Further, around this time, there were a number of uprisings against Han Zhao, each claiming to want to capture Han Zhao's crown prince Liu Can to exchange him for the former Jin emperor. Liu Can therefore reocommended that Sima Ye be executed, and Liu Cong agreed, executing him after receiving Liu Can's report.
