The
Allied powers who defeated
Nazi Germany in
World War II divided the country west of the
Oder-Neisse line into four occupation zones for administrative purposes during the period
1945-
1949. In the closing weeks of fighting in Europe, American forces had pushed beyond the previously agreed boundaries for the future zones of occupation, in some places by as much as 200 miles. The
line of contact between Soviet and American forces at the end of hostilities was temporary. After some two months during which they had held areas that had been assigned to the Soviet zone, American forces withdrew in July 1945. It has been concluded that this was a crucial move that persuaded the Soviet Union to allow American and British forces into their predesignated zones in Berlin, which occurred at roughly the same time (July 1945), although the need for intelligence gathering (see
Operation Paperclip) may also have been a factor.
