Korean Nationalism is a political and cultural movement that emphasizes the identity, unity, and sovereignty of the Korean people. It emerged in response to foreign domination, particularly during the Japanese occupation from 1910 to 1945, and has played a significant role in shaping modern South Korea and North Korea. The movement seeks to promote the Korean language, culture, and history, fostering a sense of pride among Koreans. It also advocates for the reunification of the Korean Peninsula, reflecting the desire to overcome the division created by the Korean War in the 1950s.
