Korean believed that ethnically is, Korea is a homogeneous country. And Korean also believed that Korean people are quite homogeneous and their unification lasted for almost 5,000 years. But Korean people, myth, history and culture are filled with multicultural factors. In fact, unlike Korean``s belief, many of Koreans are descendants of earlier wives of immigrants themselves. This study uses historic-anthropological interpretation to Korean``s mythic and historic characteristics to prove her identity. Unlike Korea, racism is a serious social problem in many other countries. Koreans had staked much of their administration on a policy of engagement with tolerance and harmony.

The vast and accurate knowledge of our identity will impart a special richness to our way of thinking.
