Emperor Yuan of Jin (b. 276)
Emperor Yuan of Jin (simplified Chinese: 晋元帝; traditional Chinese: 晉元帝; pinyin: Jìn Yuán Dì; Wade–Giles: Chin Yüan-ti; 276 – 3 January 323), personal name Sima Rui (司馬睿), courtesy name Jingwen (景文), was an emperor of the Jin dynasty and the first emperor of the Eastern Jin. His reign saw the steady gradual loss of Jin territory in the north, but entrenchment of Jin authority south of the Huai River and east of the Three Gorges. For generations Jin was not seriously threatened by the Wu Hu kingdoms to the north.
