See it on the Korean History map →What happened
According to the Samguk sagi, Gung Ye (궁예) was a son of a Silla king, ordered killed at birth because of an evil omen; a nurse saved him but blinded one eye. He became a monk, joined a rebel band, and in 901 declared Later Goguryeo at Songak (Kaesong). He renamed it Majin in 904 and Taebong in 911, ruling from Cheorwon. Calling himself the Maitreya Buddha, able to read minds, he grew cruel and is said to have killed his queen and two sons.
Why it matters
His state united central Korea and launched Wang Geon's career; his fall in 918 created Goryeo.
Legacy and how we know
The Samguk sagi and Goryeosa, both written by the side that overthrew him. His capital's ruins near Cheorwon lie inside the DMZ and have never been fully excavated.
Still debated
Both his royal birth and his tyranny may be exaggerated; Goryeo historians had reasons to make him look bad.

▸Gung Ye, founder of Taebong led a northern state during Later Three KingdomsWell documented
The connection
Gung Ye built the largest of the three states. He rose in a rebel band in the central region, declared Later Goguryeo in 901, renamed it Majin (904) and Taebong (911), and ruled from Cheorwon. He drew on northern loyalty to old Goguryeo and showed open hatred of Silla, reportedly calling it 'the city to be destroyed.'
When and how
901–918, in central Korea: Songak (Kaesong), then Cheorwon, today on the edge of the DMZ.
How we know
His biography in the Samguk sagi and early chapters of the Goryeosa record the names, capitals and campaigns.
Debates and open questions
How much his state rested on Goguryeo identity, versus his own Buddhist claims to kingship, is debated.
▸Gung Ye, founder of Taebong was overthrown by Wang Geon (King Taejo of Goryeo)Well documented
The connection
Wang Geon served Gung Ye from 896, won key naval victories and became chief minister. As Gung Ye grew suspicious and cruel, four generals urged Wang Geon to take power. In 918 they proclaimed him king; Gung Ye fled and, by the official account, was killed by local people.
When and how
Summer 918, at Cheorwon; the generals Hong Yu, Bae Hyeon-gyeong, Sin Sung-gyeom and Bok Ji-gyeom.
How we know
The Samguk sagi and Goryeosa both tell the story in detail, but both come from the winning side.
Debates and open questions
Whether Gung Ye was truly a tyrant or was blackened to justify a coup, and how much Wang Geon himself planned it, are debated.
