Emperor Gong's reign was brief and powerless. In fall 419, Liu Yu accepted the title Prince of Song. In spring 420, Liu Yu, then at Shouyang (壽陽, in modern Lu'an, Anhui) sent his assistant Fu Liang to Jiankang to pressure Emperor Gong to yield the throne. Emperor Gong responded by summoning Liu Yu back to the capital in summer 419, and Fu then offered him a draft of an abdication edict, requesting that he write it personally. Sima Dewen did so, and then left the palace and went to his old house while he was Prince of Langya. Three days later, Liu Yu took the throne and established Liu Song (as Emperor Wu), ending Jin.
