Goryeo, also known as Koryŏ (Hangul: 려; hanja: 高麗; 918-1392), was a Korean dynasty established in 918 by King Taejo. This kingdom later gave name to the modern state of Korea. It united the Later Three Kingdoms in 936 and ruled most of the Korean peninsula until it was removed by the leader of the Joseon dynasty in 1392. The Goryeo dynasty expanded its borders to present-day Wonsan in the north-east (936-943) and the Amnok River (993) and finally almost the whole of the Korean peninsula (1374). By the 14th century Goryeo had lost much of its power under Yuan Dynasty pressure. Although King Gongmin managed to free his kingdom from the Mongol influence, the Goryeo general Yi Seonggye revolted and overthrew the last king of Goryeo, King Gongyang in 1392. Gongyang was killed in 1394.
