This article explores the history of Korea's fight for independence from Japan, which ruled over the country from 1910 to 1945. The Japanese government imposed strict policies on Koreans, forcing them to adopt Japanese language and culture and denying them basic rights. However, Koreans did not give up their fight for independence and launched a peaceful protest known as the March 1st Movement in 1919. The United Nations played a crucial role in helping Korea establish a free and democratic government, while Korean guerrilla fighters and the Korean Independence Army fought against Japanese oppression. International pressure also led to Japan relinquishing control over Korea after World War II ended, resulting in the establishment of the Republic of Korea in 1948. The legacy of Korea's independence movement is still celebrated today as an inspiration for other countries fighting against oppression and colonialism.
