Integration with the West
The American Marshall plan of 1947 aimed to stabilise Europe and Germany economically so the USA could expand their foreign trade all over the world. Due to the success of this reconstruction programme the German economy recovered and achieved an economic boom in the 1950s. Initially the USA had offered their plan to all Eastern European states including the Soviet Union. As was to be expected however the Soviets refused the plan as their economical system was not compatible with the conditions of the Marshall plan. Thereupon the USA declared their cooperation with the Soviet Union as officially terminated.
As the Soviet Union had extended its domain over East Europe by installing several satellite countries the USA altered their policies in 1947, led by President Harry Truman, and pursued the containment policy. This policy was designed to restrict the political and economical influence the Soviet Union possessed over Europe. The spreading of the communistic ideology over Europe would have influenced the American foreign trade and thus their national economy. In order to prohibit this development President Truman passed the so called Truman-doctrine.
Prohibition of the Communist Party of Germany
The Federal Government had ascertained the unconstitutionality of the Communist Party of Germany in 1951, however the official ban was only declared by the Federal Constitutional Court in 1961. The Communist Party of Germany was classified as a radical party that followed the Marxist-Leninist principles similarly to the Communist Party of the Soviet Union. Adenauer, the Federal Chancellor at the time aimed to protect to free and democratic fundamental order and hoped to avert political influence of the Soviet Union in West Germany.
Konrad Adenauer was the first Chancellor West Germany had that made an effort to integrate Germany economically and politically within the western nations, leading for example, to Germany joining the NATO in 1954 and to the foundation of the European Economic Community in 1957. Adenauer hoped to convince the GDR to a reunification by presenting the western economy as reinvigorated. However this so called Magnet theory led to an even graver estrangement between East and West and thus to an intensification of the conflict.
