After the end of World War II in Europe, what remained of pre-war Germany west of the Oder-Neisse line was divided into four occupation zones (as per the Potsdam Agreement), each one controlled by one of the four occupying Allied powers: the United States, the United Kingdom, France and the Soviet Union. The capital of Berlin, as the seat of the Allied Control Council, was similarly subdivided into four sectors despite the city's location, which was fully within the Soviet zone.
Within two years, political divisions increased between the Soviets and the other occupying powers. These included the Soviets' refusal to agree to reconstruction plans making post-war Germany self-sufficient, and to a detailed accounting of industrial plants, goods and infrastructure - some of which was already removed by the Soviets. France, the United Kingdom, the United States and the Benelux countries later met to combine the non-Soviet zones of Germany into one zone for reconstruction, and to approve the extension of the Marshall Plan.
Eastern Bloc and the Berlin airlift

Following World War II, Soviet leader Joseph Stalin headed a group of nations on his Western border, the Eastern Bloc, that then included Poland, Hungary and Czechoslovakia, which he wished to maintain alongside a weakened Soviet-controlled Germany. As early as 1945, Stalin revealed to German communist leaders that he expected to slowly undermine the British position within the British occupation zone, that the United States would withdraw within a year or two, and that nothing would then stand in the way of a united communist Germany within the bloc.
The major task of the ruling communist party in the Soviet zone was to channel Soviet orders down to both the administrative apparatus and the other bloc parties, which in turn would be presented as internal measures. Property and industry was nationalized in the East German zone. If statements or decisions deviated from the described line, reprimands and (for persons outside public attention) punishment would ensue, such as imprisonment, torture and even death.
Indoctrination of Marxism-Leninism became a compulsory part of school curricula, sending professors and students fleeing to the West. The East Germans created an elaborate political police apparatus that kept the population under close surveillance, including Soviet SMERSH secret police.
In 1948, following disagreements regarding reconstruction and a new German currency, Stalin instituted the Berlin Blockade, preventing food, materials and supplies from arriving in West Berlin. The United States, the United Kingdom, France, Canada, Australia, New Zealand and several other countries began a massive "airlift", supplying West Berlin with food and other supplies. The Soviets mounted a public relations campaign against the Western policy change. Communists attempted to disrupt the elections of 1948, preceding large losses therein, while 300,000 Berliners demonstrated for the international airlift to continue. In May 1949, Stalin lifted the blockade, permitting the resumption of Western shipments to Berlin.
The German Democratic Republic (East Germany) was declared on 7 October 1949. By a secret treaty, the Soviet Ministry of Foreign Affairs accorded the East German state administrative authority, but not autonomy. The Soviets permeated East German administrative, military and secret police structures and had full control.
East Germany differed from West Germany (Federal Republic of Germany), which developed into a Western capitalist country with a social market economy ("Soziale Marktwirtschaft" in German) and a democratic parliamentary government. Continual economic growth starting in the 1950s fuelled a 20-year "economic miracle" ("Wirtschaftswunder"). As West Germany's economy grew, and its standard of living steadily improved, many East Germans wanted to move to West Germany.
Emigration westward in the early 1950s
After the Soviet occupation of Eastern Europe at the end of World War II, the majority of those living in the newly acquired areas of the Eastern Bloc aspired to independence and wanted the Soviets to leave. Taking advantage of the zonal border between occupied zones in Germany, the number of GDR citizens moving to West Germany totaled 187,000 in 1950; 165,000 in 1951; 182,000 in 1952; and 331,000 in 1953. One reason for the sharp 1953 increase was fear of potential further Sovietization, given the increasingly paranoid actions of Joseph Stalin in late 1952 and early 1953. 226,000 had fled in just the first six months of 1953.
