Emperor Kang of Jin

Emperor Kang of Jin (simplified Chinese: 晋康帝; traditional Chinese: 晉康帝; pinyin: Jìn Kāng Dì; Wade–Giles: Chin K'ang-ti; 322 – 17 November 344), personal name Sima Yue (司馬岳), courtesy name Shitong (世同), was an emperor of the Eastern Jin Dynasty (265-420). He was a son of Emperor Ming and younger brother (by the same mother) of Emperor Cheng. His reign was brief—only two years.

Prior to reign

Sima Yue was born in 322 as the second son of Emperor Ming, by his wife Empress Yu Wenjun. After his father died in 325 and was succeeded by his brother Emperor Cheng, Sima Yue was created the Prince of Wu in 326. In 327, because his uncle Sima Yu the Prince of Langye wanted to yield that more honorific title, Sima Yu was created the Prince of Kuaiji and Sima Yue was created the Prince of Langye. It is not known where Sima Yue was during the Su Jun Disturbance of 326–328—whether he was captured and held hostage like his emperor brother, at his principality of Wu (which Su Jun did not occupy), or elsewhere. During his brother's reign, he received a progression of offices, but did not appear to actually participate in major decision-making.
