The People's Republic of Korea was a short-lived provisional government that was organized at the time of the surrender of the Empire of Japan at the end of World War II. It was proclaimed on 6 September 1945, as Korea was being divided into two occupation zones, with the Soviet Union occupying the north and the United States occupying the south. Based on a network of people's committees, it presented a program of radical social change.

The division of Korea began on August 15, 1945 when the official announcement of the surrender of Japan was released, thus ending the Pacific Theater of World War II. During the war, the Allied leaders had already been considering the question of Korea's future following Japan's eventual surrender in the war. The leaders reached an understanding that Korea would be liberated from Japan but would be placed under an international trusteeship until the Koreans would be deemed ready for self-rule. In the last days of the war, the United States proposed dividing the Korean peninsula into two occupation zones with the 38th parallel as the dividing line. The Soviets accepted their proposal and agreed to divide Korea.
