Emperor Fei of Jin

Emperor Fei of Jin (晋废帝/晉廢帝, pinyin Jìn Fèidì, Wade-Giles Chin Fei-ti) (342 – November 23, 386), personal name Sima Yi (司馬奕), courtesy name Yanling (延齡), was an emperor of the Eastern Jin Dynasty (265-420) in China. He was the younger brother (from the same mother) of Emperor Ai and later deposed by military leader Huan Wen. The title that he is normally referred to, "Emperor Fei", is not a posthumous name as is usually the case with imperial common titles, but rather signified that he was deposed (with "Fei" (廢) meaning "depose"). He is also commonly known by the title he was given after his removal, Duke of Haixi (海西公).
