Post-war Germany occupation zones and Berlin sectors

Summary

After World War II, Germany was divided into four Allied occupation zones—controlled by the United States, the United Kingdom, France, and the Soviet Union—under the Potsdam Agreement. Berlin, although located entirely within the Soviet zone, was also split into four Allied sectors because it served as the seat of the Allied Control Council. Over the next two years, tensions between the Soviet Union and the other occupying powers grew, including disputes over reconstruction plans and the accounting for industrial assets and infrastructure removed by the Soviets. As Cold War divisions hardened, the Soviet occupation zone evolved into the German Democratic Republic (GDR) with a centrally planned socialist system and repressive party rule, while the Western zones developed toward the Federal Republic of Germany (FRG). Migration from East to West increased as people sought better living conditions and political freedom, often using Berlin as a route. In 1948, the Soviet Union responded to Western moves toward separate governance and expanded aid by imposing the Berlin Blockade, cutting land access to West Berlin; the Western Allies countered with the Berlin airlift, supplying the city by air until the blockade was lifted in 1949. This occupation-zone and sector structure in Berlin set the stage for later efforts to restrict movement between East and West, culminating in the construction of the Berlin Wall in 1961.

Key Points

• 1

  Post-war Germany was divided into four Allied occupation zones, and Berlin was similarly divided into four sectors despite being inside the Soviet zone.

• 2

  Rising Cold War tensions and incompatible reconstruction and governance plans increased division between the Soviet-controlled area and the Western zones.

• 3

  East-to-West migration through Berlin grew into a major issue, leading to the 1948 Berlin Blockade and the Western airlift supplying West Berlin until 1949.
