At the dawn of the first century, Korea had contacts with the Japanese islands, and the highly developed culture of China was embraced. After unification of the country into a single state by Silla in A.D. 668, however, the Korean people were more or less confined to the Korean peninsula. This later led to isolationism in the mentality of the Korean people and their society. The Koryo dynasty in A.D. 936 repulsed alien invaders from the north, and the people succeeded in developing a Buddhist world of their own. This cultural heritage led to the Yi dynasty in 1392 and national integrity derived from Confucianism. The Japanese annexed Korea in 1910 as a result of the relentless pressure and exploitation of Japanese capitalism. Korea as a Japanese colony then went through a period of stagnation during the first half of the 20th century (Kiln, 1970).
