To avoid Germany rearming, the country was divided into four zones U.S., France, Britain, and Russia were each in control of one zone. West Germany was a democracy, East Germany was a communist nation. Berlin was located in East Germany and it was also split into four zones. Russia cut off the railway to West Berlin to make West Berlin give itself over to the East. America's response was the Berlin Airlift where the U.S. flew in needed supplies to West Berlin. The operation worked and the Soviet Union ended their blockade the next year.
