Ethnic Groups in South Korea's History

South Korea is remarkably ethnically homogeneous; Koreans comprise the vast majority. Historical influences include:

1. Jomon people: Ancient inhabitants (c. 10,000–300 BC), hunter-gatherers.
2. Three Kingdoms period: Goguryeo, Baekje, Silla (1st millennium AD), influenced by China (Buddhism, writing).
3. Foreign invasions: China, Mongolia, Japan—cultural impact but no major demographic shift.
4. Modern immigrants: Small communities from China, Vietnam, Philippines.
5. Korean diaspora: Large populations in U.S., Japan, China—culturally tied but not resident ethnic groups.

South Korea's identity remains overwhelmingly Korean.
