1952 saw the creation of the European Coal and Steel Community, which was declared to be "a first step in the federation of Europe", starting with the aim of eliminating the possibility of further wars between its member states by means of pooling the national heavy industries. The founding members of the Community were Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany.In 1957, the six countries signed the Treaty of Rome, which extended the earlier co-operation within the European Coal and Steel Community (ECSC) and created the European Economic Community (EEC), establishing a customs union. They also signed another treaty on the same day creating the European Atomic Energy Community (Euratom) for co-operation in developing nuclear energy. Both treaties came into force in 1958.
