Gyeon Hwon
Not only was Hubaekje reeling from military defeats, the kingdom was in internal disarray. In 935, Gyeon Hwon's eldest son Singeom, who had been slighted as heir to the throne in favor of his younger brother Geumgang, overthrew Gyeon Hwon with the aid of his brothers Yanggeom and Yonggeom. Singeom killed Geumgang and confined Gyeon Hwon to Geumsan Temple, but Gyeon Hwon escaped and fled to Goryeo and his old enemy Wang Geon, who welcomed him and provided him with land and slaves.
