In his later days, it is recorded that Gung Ye started to suffer from paranoia. He accused many arbitrarily of treason and sentenced anyone who opposed him to death, including Kang, one of his wives, and his two sons. As a result, in 918 four of his own top generals – Hong Yu (hangul:홍유, hanja:洪儒), Bae Hyeongyeong (hangul:배현경, hanja:裵玄慶), Sin Sung-gyeom and Bok Jigyeom (hangul:복지겸, hanja:卜智謙) – overthrew Taebong and enthroned Wang Geon, one of Gung Ye's followers and the previous chief minister, of his nation, as king. Gung Ye is said to have escaped the palace, but was killed shortly thereafter either by a soldier or by peasants who mistook him for a thief.
