Emperor Min of Jin (simplified Chinese: 晋愍帝; traditional Chinese: 晉愍帝; pinyin: Jìn Mǐn Dì; Wade–Giles: Chin Min-ti; 300 – February 7, 318), personal name Sima Ye (司馬鄴 or 司馬業), courtesy name Yanqi (彥旗), was an emperor of the Jin Dynasty (265-420) and the last of the Western Jin.
Emperor Min surrendered in 316 to Liu Yao, a general of the Xiongnu state Han Zhao, and was later executed by Liu Cong, the emperor of Han Zhao, in 318.
Sima Ye was a son of Sima Yan (司馬晏) the Prince of Wu, a son of Jin's founding emperor Emperor Wu, and Lady Xun, a daughter of Xun Xu (荀勗)—Xun Shuang's descendant. However, he was posthumously adopted by his uncle Sima Jian (司馬柬) 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 311, Prince Ye's uncle Emperor Huai 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 (密縣, in modern Zhengzhou, Henan) when he encountered his uncles, the Jin officials Xun Fan (荀藩) and Xun Zu (荀組), who decided to support him as their leader. Later that year, the general Yan Ding (閻鼎) tried to escort Prince Ye into the Guanzhong region (modern central Shaanxi), 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 (賈疋), 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.
