The People's Republic of Korea (PRK) 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. In the south, the US military government outlawed the PRK on 12 December 1945, while in the north, the Soviet authorities co-opted the committees into the structure of the emerging Democratic People's Republic of Korea (North Korea).
