The European Defence Community (EDC) emerged from the Pleven plan proposed in 1950 by René Pleven, the French Prime Minister, in response to the American call for the rearmament of West Germany. The intention was to form a pan-European defence force as an alternative to Germany's proposed accession to NATO, meant to harness its military potential in case of conflict with the Soviet bloc. The EDC was to include West Germany, France, Italy, and the Benelux countries. Just as the Schuman Plan was designed to end the risk Germany having the economic power on its own to make war again, the Pleven Plan and EDC were meant to prevent the military possibility of Germany's making war again. A treaty was signed on 27 May 1952, but the plan never went into effect. Instead Germany was admitted into NATO.
During the late 40s, the divisions created by the Cold War were becoming more and more evident. The United States looked with suspicion at the growing power of the USSR and European states felt vulnerable, fearing a possible Soviet occupation. In this climate of mistrust and suspicion, the United States considered the rearmament of West Germany as a possible solution to enhance the security of Europe and of the whole Western bloc. In September 1950, Dean Acheson proposed a new plan to the European states; the American plan, called package, sought to enhance NATO's defense structure, creating 12 West German divisions. However, after the destruction that Germany had caused during World War II, European countries, and in particular France, were not ready to see the reconstruction of the German military. Finding themselves in the midst of the two superpowers, they looked at this situation as a possibility to enhance the integration process, trying to obviate the loss of military influence caused by the new bipolar order. On 24 October 1950, France's Prime Minister René Pleven proposed a new plan, which took his name, that aimed to create a supranational European Army. With this project, France tried to satisfy America's demands, avoiding, at the same time, the creation of German divisions, and thus the rearmament of Germany.
