Numerous different international treaties and peace accords have been signed in Paris throughout history. The term Treaty of Paris most often refers to the Treaty establishing the European Coal and Steel Community, which was signed in Paris on 18 April 1951 at the initiative of French Foreign Minister Robert Schuman. The Treaty, which was ratified by Belgium, France, Italy, Luxembourg, the Netherlands and the former Federal Republic of Germany, entered into force on 26 July 1952 and remained in force until 23 July 2005.
The establishing of the Community was the beginning of the realisation of a vision of efforts to establish peace and overcome nationalism in Europe, which was increasingly present in the exhausted countries after the end of the Second World War.
The successful cooperation in the European Coal and Steel Community led six years later to the founding of the European Economic Community and the European Atomic Energy Community by the same countries. Both treaties were signed on the same day in Rome and are now referred to as the Treaties of Rome. With the signing of these treaties, the path to a union of European countries was laid out. The Treaty of Paris was thus the formal beginning of the process which finally led to the creation of the European Union, and therefore the anniversary of its signing is an important date for all EU Member States.
