恭帝
Emperor Gong's reign was a brief and powerless one. He created his wife Princess Chu empress in spring 419. He also promoted Liu Yu, then carrying the title Duke of Song, to the Prince of Song, which Liu Yu initially declined but accepted in fall 419. In spring 420, Liu Yu, then at Shouyang 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, ending Jin.
