The Three Kingdoms:
During the 6th century A.D. what we now call the Korean peninsula was divided into three kingdoms; Koguryo, Paekje and Silla.
Koguryo (37 B.C.- 668 A.D.)- Koguryo was the largest kingdom. It occupied the southern section of Manchuria and the northern section of the Korean peninsula. Paekje (18 B.C. - 600 A.D.)- Paekje was situated along the Han River and in southwestern Korea. Silla (57 B.C.- 936 A.D.)- Silla was the last, and smallest of the kingdoms and located on the southeastern tip of the Korean peninsula. Archeological findings during these times such as the mural paintings on the royal tombs during the Koguryo period, stone sculptures at pagodas during the Silla period and documents written in the Paekje period, show techniques and fighting stances that were probably the first forms of Taekwondo.
The three kingdoms were at war with each other and constantly fought for new ground on the peninsula. Silla, being the smallest and weakest militarily began to have a difficult time protecting itself against the other kingdoms and so took an action which would turn out to be a key point in Korean history.
