Emperor Fei of Jin

Emperor Fei of Jin, personal name Sima Yi (司馬奕), courtesy name Yanling (延齡), was an emperor of the Eastern Jin Dynasty in ancient China. He was the younger full-brother of Emperor Ai; he was later deposed by military leader and regent Huan Wen. The title that he is normally referred to, "Emperor Fei", is not a posthumous name or temple name as is usually the case with Chinese imperial titles, but rather signified that he was deposed. He is also commonly known by the title he was given after his removal, Duke of Haixi (海西公); he is also the last descendant of Emperor Ming to become emperor of the Eastern Jin.
