The Korean independence movement was a series of diplomatic and militant efforts to liberate Korea from Japanese rule. The movement began around the late 19th or early 20th century, and ended with the surrender of Japan in 1945. As independence activism on the peninsula was largely suppressed by Japan, many significant efforts were conducted abroad by the Korean diaspora, as well as by a number of sympathetic non-Koreans.

The Cairo Declaration was the outcome of the Cairo Conference in Cairo, Egypt, on 27 November 1943. President Franklin Roosevelt of the United States, Prime Minister Winston Churchill of the United Kingdom, and Generalissimo Chiang Kai-shek of the Republic of China were present. The declaration developed ideas from the 1941 Atlantic Charter, which was issued by the Allies of World War II to set goals for the post-war order. The Cairo Communiqué was broadcast through radio on 1 December 1943.
