The resulting ECSC introduced a common steel and coal market across the member countries with freely set market prices, and without internal import/export duties or subsidies. The success of ECSC led to further steps, foreseen by Schuman, being taken with the creation of the European Economic Community and the European Atomic Energy Community. The two European Commissions of the latter Rome Treaties and the High Authority merged into a single European Commission in the 1960s. Further intergovernmental, (non-supranational), bodies and areas of activities were created leading to the creation of the European Union in 1993.
