高麗太祖
The state's initial name was Goryeo, after the official name of Goguryeo, a previous state in Manchuria and the northern Korean Peninsula, from the 5th century. Gung Ye changed the state's name to Majin in 904, and eventually to Taebong in 911. When Wang Geon overthrew Gung Ye and enthroned himself as Taejo of Goryeo, he restored its original name.
