The Allied Occupation refers to the period after World War II when the victorious Allied powers, including the United States, Soviet Union, United Kingdom, and France, took control of Germany and Japan. This occupation aimed to demilitarize, democratize, and rebuild these nations, ensuring they would not pose a future threat. In Germany, the country was divided into four zones, each managed by one of the Allied powers. In Japan, the occupation was led primarily by the United States under General Douglas MacArthur, who implemented significant political and economic reforms, including a new constitution that promoted democracy and civil rights.
