Taejo of Goryeo
Hubaekje (900–936) was founded by Gyeon Hwon, who was a general during Later Silla's period of decline. Thus began the Later Three Kingdoms period. Hubaekje met its downfall at the hands of Gyeon Hwon himself, who later led the Goryeo armies alongside Taejo of Goryeo to capture Singeom, the prince of Hubaekje, who had betrayed Gyeon Hwon.
