The Treaty establishing the European Defence Community, also known as the Treaty of Paris, is an unratified treaty signed on 27 May 1952 by the six 'inner' countries of European integration: the Benelux countries, France, Italy, and West Germany. The treaty would have created a European Defence Community (EDC) with a pan-European defence force. The treaty failed to obtain ratification in the French parliament and it was never ratified by Italy, so it consequently never entered into force. Instead, the London and Paris Conferences provided for West Germany's accession to NATO and the Western European Union.

The European Union (EU) and the North Atlantic Treaty Organisation (NATO) are two main treaty-based Western organisations for cooperation between member states, both headquartered in Brussels, Belgium. Their natures are different and they operate in different spheres: NATO is a purely intergovernmental organisation functioning as a military alliance whose primary task is to implement article 5 in the North Atlantic Treaty on collective territorial defence. The EU on the other hand is a partly supranational and partly intergovernmental sui generis entity akin to a confederation that entails wider economic and political integration. Unlike NATO, the EU pursues a foreign policy in its own right - based on consensus, and member states have equipped it with tools in the field of defence and crisis management; the Common Security and Defence Policy (CSDP) structure.
