Monetary reformation in the western zone
Due to the War the reichsmarkThe Reichsmark was the currency in Germany from 1924 until 20 June 1948 had lost its relevance internationally. The enormous costs of the war and the inflationary monetary policy had led the German currency to its ruin. As a consequence many decided to trade on the black market rather than with money. The USA witnessed this process with careful attention and realised that the decay of monetary value would hamper the German economy to great extent. Consequently the German mark. The Soviet responded by introducing the East German markThe East German mark was the currency in the German Democratic Republic until 1990 in their territories, thereby even exacerbating the division between East and West1.
Closure of the transit routes
The course of action taken by the west powers prompted the Soviets to block all transit routes to West Berlin; they distanced themselves from the West as they did not approve of market economy, the Marshall plan and the monetary reform. Rightly they feared a mass get-away from their administrative zone if the economy in the west recovered. Hence the Soviet Military Administration blocked all traffic routes to West Berlin, in order to force the west powers to relinquish their claims on Berlin. This action however breached the agreements made on the Potsdam Conference and forced the USA to react to the blockadeAim of the blockade was to force the western powers to allow the Soviet zone to start supplying Berlin with food, fuel, and aid, thereby giving the Soviets practical control over the entire city.
In consequence of this the west powers agreed to provide West Berlin with aliments over an airliftAn airlift is the organized delivery of supplies or personnel primarily via aircraft. This meant that the US flew to Berlin with their airplanes, in retro perspective called “Rosinenbomer”. From the 24th of June 1948 until the 12th of May 1949 the sole supply of nourishments for West Berlin took place via air. In the End the Soviets yielded and the attempt to overtake the whole city failed, the tension between East and West however became ever more severe2.
