Gung Ye
According to legend, Gung Ye was a son of either King Heonan or King Gyeongmun of Silla. A soothsayer prophesied that the newborn baby would bring disaster to Silla, so the King ordered his servants to kill him. However, his nurse hid Gung Ye and raised him secretly. He joined Yang Gil's rebellion force in 892. Silla, after nearly a millennium as a centralized kingdom, was quickly declining, and Gung Ye instigated his own rebellion and absorbed Wang Geon's forces at Songak. In 898, He set up the capital in Songak. He eventually defeated Yang Gil and other local lords in central Korea to proclaim himself king in 901.
