Taejo of Goryeo (January 31, 877 – July 4, 943), also known as Taejo Wang Geon (Wang Kon, 왕건), was the founder of the Goryeo Dynasty, which ruled Korea from the 10th to the 14th century. Taejo ruled from 918 to 943.
Taejo was born in 877 and was a descendant of a merchant family at Songdo (modern Kaesong), who controlled trade on the Yeseong River. His father, Wang Yung (왕륭, 王隆), gained much wealth from trade with China. His ancestors were known to have lived within the boundaries of ancient Goguryeo, thus making Wang Geon a man of Goguryeo by descent.
Taejo began his career in the turbulent Later Three Kingdoms (hanja: 後三國時代 ). In the later years of Silla, many local leaders and bandits rebelled against the rule of Queen Jinseong, who did not have strong enough leadership or policies to improve the condition of the people. Among those rebels, Gung Ye (궁예; 弓裔) of the northwestern region and Gyeon Hwon (견훤; 甄萱) of the southwest gained more power. They defeated and absorbed many of the other rebel groups as their troops marched against local Silla officials and bandits. In 895, Gung Ye led his forces into the far northwestern part of Silla, where Songdo was located. Taejo's father, Wang Yung (later Sejo of Goryeo), along with many local clans, quickly surrendered to Gung Ye. Wang Geon followed his father into service under Gung Ye, the future leader of Taebong, and he began his service under Gungye's command.
Goryeo, also known as Koryŏ (Hangul: 고려; hanja: 高麗; Korean pronunciation: [koɾjʌ]; 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).
Two of this period's most notable products are celadon pottery and the Tripitaka Koreana—the Buddhist canon (Tripiṭaka) carved onto roughly 80,000 woodblocks and stored (and still remaining) at Haeinsa. Subjects and officials of Goryeo also created the world's first metal-based movable type in 1234; the oldest surviving movable metal type book, the Jikji, was printed in 1377.
In 668, Silla conquered Baekje and Goguryeo with an alliance with Tang China, but by the late 9th century it was tottering, its monarchs being unimaginative and pressed by the power of powerful statesmen. Many robbers and outlaws agitated and in 900 Gyeon Hwon revolted from Silla control in the Jeolla region as the state of Later Baekje; the year after, Gung Ye revolted from the northern regions as Taebong. A son of a regional lord, Wang Geon, joined Taebong as a general.
