The Liu Song dynasty (420–479 CE; Chinese: 劉宋), also known as Former Song (前宋) or Southern Song (南朝宋), was the first of the four Southern Dynasties in China, succeeding the Eastern Jin and followed by the Southern Qi.. The dynasty was founded by Liu Yu (劉裕) (363–422 CE), whose surname together with "Song" forms the common name for the dynasty, the Liu Song.
