Korean nationalist leaders were individuals who played significant roles in advocating for Korea's independence from foreign rule, particularly during the Japanese occupation from 1910 to 1945. They sought to promote Korean identity, culture, and sovereignty, often through political activism, education, and cultural movements. Notable figures include Kim Il-sung, Syngman Rhee, and Ahn Chang-ho. These leaders organized protests, established political parties, and formed alliances with other nations to gain support for Korea's independence. Their efforts contributed to the eventual liberation of Korea in 1945 and the subsequent division of the peninsula into North Korea and South Korea.
