The ECSC treaty expired in 2002, fifty years after it came into force,[1] but its institutions were taken over in 1967 following the Merger Treaty. The political centres were Luxembourg and Strasbourg, later also Brussels. Initial founding languages, before the merger and subsequent enlargements, were Dutch, French, German and Italian.

The European Coal and Steel Community (ECSC) was a European organization created after World War II to integrate Europe's coal and steel industries into a single common market based on the principle of supranationalism which would be governed by the creation of a High Authority which would be made up of appointed representatives from the member states who would not represent their national interest, but would take and make decisions in the general interests of the Community as a whole.^[2] It was formally established in 1951 by the Treaty of Paris, signed by Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany and was generally seen as the very first step in the process of European integration following the end of the Second World War in Europe. The organization's subsequent enlargement of both members and duties ultimately led to the creation of the European Union.

The ECSC was first proposed via the Schuman Declaration by French foreign minister Robert Schuman on 9 May 1950 (commemorated in the EU as Europe Day), the day after the fifth anniversary of the end of World War II, to prevent another war between France and Germany. He declared "the solidarity in production" from pooling "coal and steel production" would make war between the two "not only unthinkable but materially impossible".^[3] The Treaty created a common market among member states that stipulated free movement of goods (without customs duties or taxes) and prohibited states from introducing unfair competitive or discriminatory practices.^[4]

Its terms were enforced by four institutions: a High Authority composed of independent appointees, a Common Assembly composed of national parliamentarians, a Special Council composed of national ministers, and a Court of Justice. These would ultimately form the blueprint for today's European Commission, European Parliament, the Council of the European Union, and the Court of Justice of the European Union, respectively.

The ECSC set an example for the pan-European organizations created by the Treaty of Rome in 1957: the European Economic Community and European Atomic Energy Community, with whom it shared its membership and some institutions. The 1967 Merger (Brussels) Treaty merged the ECSC's institutions into the European Economic Community, but the former retained its own independent legal personality until the Treaty of Paris expired in 2002, leaving its activities fully absorbed by the European Community under the frameworks of the Treaties of Amsterdam and Nice.
