Goryeo, also known as
Koryo (; ; 918–1392), was a Korean dynasty established in 918 by
King Taejo. This kingdom later gave name to the modern exonym "
Korea". It united the
Later Three Kingdoms in 936 and ruled most of the
Korean Peninsula until it was removed by the founder of the
Joseon in 1392. Goryeo expanded Korea's borders to present-day
Wonsan in the northeast (936–943), the
Yalu River (993) and finally almost the whole of the Korean Peninsula (1374).
