Gung Ye
Taejo began his career in the turbulent Later Three Kingdoms (). In the later years of Silla, many local leaders and bandits rebelled against the rule of Queen Jinseong, who did not have strong enough leadership or policies to improve the condition of the people. Among those rebels, Gung Ye (궁예; 弓裔) of the northwestern region and Gyeon Hwon (견훤; 甄萱) of the southwest gained more power. They defeated and absorbed many of the other rebel groups as their troops marched against local Silla officials and bandits. In 895, Gung Ye led his forces into the far northwestern part of Silla, where Songdo was located. Taejo's father, Wang Yung (later Sejo of Goryeo), along with many local clans, quickly surrendered to Gung Ye. Wang Geon followed his father into service under Gung Ye, the future leader of Taebong, and he began his service under Gungye's command.
