A supranational union is a type of international organization that is empowered to directly exercise some of the powers and functions otherwise reserved to states. A supranational organization involves a greater transfer of or limitation of state sovereignty than other kinds of international organizations. The European Union (EU) has been described as a paradigmatic case of a supranational organization, as it has deep political, economic and social integration, which includes a common market, joint border control, a supreme court, and regular popular elections. Another method of decision-making in international organisations is intergovernmentalism in which state governments play a more prominent role. Origin as a legal concept After the dropping of atomic bombs on Hiroshima and Nagasaki in August 1945, Albert Einstein spoke and wrote frequently in the late 1940s in favour of a "supranational" organization to control all military forces except for local police forces, including nuclear weapons. He thought this might begin with the United States, the United Kingdom, and the Soviet Union, and grow to encompass most other nations, presenting this as the only way to avoid nuclear war. He broached the idea in the November 1945 and November 1947 articles in The Atlantic Monthly that described how the constitution of such an organization might be written. In an April 1948 address at Carnegie Hall, he reiterated: "There is only one path to peace and security: the path of supranational organization." Thanks to his celebrity, Einstein's ideas on the subject generated much discussion and controversy, but the proposal did not generate much support in the West and the Soviet Union viewed it with hostility. With its founding Statute of 1949 and its Convention of Human Rights and Fundamental Freedoms, which came into force in 1953, the Council of Europe created a system based on human rights and the rule of law. Robert Schuman, French foreign minister, initiated the debate on supranational democracy in his speeches at the United Nations, at the signing of the council's Statutes and at a series of other speeches across Europe and North America. The term "supranational" occurs in an international treaty for the first time (twice) in the Treaty of Paris, 18 April 1951. This new legal term defined the community method in creating the European Coal and Steel Community and the beginning of the democratic re-organisation of Europe. It defines the relationship between the High Authority or European Commission and the other
