Gyeon Hwon vs Henry III

Gyeon Hwon, a former Silla general, led a rebellion and established the kingdom of Later Baekje in southwestern Korea. He declared himself king, reviving the name of the ancient Baekje kingdom and initiating the Later Three Kingdoms period.

Gyeon Hwon's forces were defeated by the Goryeo army under King Taejo at Gochang. This battle marked a turning point in the Later Three Kingdoms period, weakening Later Baekje and strengthening Goryeo's position.

Gyeon Hwon was deposed by his son, Gyeon Singeom, who seized the throne in a coup. The rebellion was fueled by Gyeon Hwon's favoritism toward his youngest son, leading to internal strife within Later Baekje.

After being deposed, Gyeon Hwon defected to Goryeo and was welcomed by King Taejo. He provided military intelligence and assistance to Goryeo, contributing to the eventual conquest of Later Baekje in 936.

Gyeon Hwon died in Goryeo shortly after the fall of Later Baekje. His death marked the end of the Later Three Kingdoms period and the unification of Korea under Goryeo.
