The European Coal and Steel Community (ECSC) was established in 1951, creating a supranational authority over the coal and steel industries of the six founding members: France, West Germany, Italy, Belgium, Luxembourg, and the Netherlands. This was the first step towards European integration and supranational decision-making, leading eventually to the formation of the European Union. The Council of Rome (1957), the European Atomic Energy Community (1957), and Pax Romana (a period of relative peace and stability in the Roman Empire) are not relevant to the formation of the first major European supranational authority.
