A Korean nationalist leader is an individual who advocates for the independence and sovereignty of Korea, particularly during periods of foreign occupation or influence. These leaders often promote cultural identity, national pride, and political autonomy, aiming to unite the people against colonial powers. One prominent example is Kim Il-sung, who played a significant role in the Korean independence movement and later became the first leader of North Korea. His efforts were part of a broader struggle against Japanese colonial rule, which lasted from 1910 to 1945, and he is remembered for his contributions to Korean nationalism.
