Following the two devastating World                            Wars in the first half of the 20th                            century, a number of European leaders                            in the late 1940s became convinced that                            the only way to establish a lasting                            peace was to reconcile the two chief                            belligerent nations - France and                            Germany - both economically and                            politically. In 1950, the French                            Foreign Minister Robert SCHUMAN                            proposed an eventual union of all                            Europe, the first step of which would                            be the integration of the coal and                            steel industries of Western Europe. The                            following year, the European Coal and                            Steel Community (ECSC) was set up when                            six members, Belgium, France, West                            Germany, Italy, Luxembourg, and the                            Netherlands, signed the Treaty of                            Paris.                          
                            The ECSC was so successful that within                            a few years the decision was made to                            integrate other elements of the                            countries' economies. In 1957,                            envisioning an "ever closer union," the                            Treaties of Rome created the European                            Economic Community (EEC) and the                            European Atomic Energy Community                            (Euratom), and the six member states                            undertook to eliminate trade barriers                            among themselves by forming a common                            market. In 1967, the institutions of                            all three communities were formally                            merged into the European Community                            (EC), creating a single Commission, a                            single Council of Ministers, and the                            body known today as the European                            Parliament. Members of the European                            Parliament were initially selected by                            national parliaments, but in 1979 the                            first direct elections were undertaken                            and have been held every five years                            since.                          
                            In 1973, the first enlargement of the                            EC took place with the addition of                            Denmark, Ireland, and the United                            Kingdom. The 1980s saw further                            membership expansion with Greece                            joining in 1981 and Spain and Portugal                            in 1986. The 1992 Treaty of Maastricht                            laid the basis for further forms of                            cooperation in foreign and defense                            policy, in judicial and internal                            affairs, and in the creation of an                            economic and monetary union - including                            a common currency. This further                            integration created the European Union                            (EU), at the time standing alongside                            the European Community. In 1995,                            Austria, Finland, and Sweden joined the                            EU/EC, raising the membership total to                            15.                          
                            A new currency, the euro, was launched                            in world money markets on 1 January                            1999; it became the unit of exchange                            for all EU member states except                            Denmark, Sweden, and the United                            Kingdom. In 2002, citizens of those 12                            countries began using euro banknotes                            and coins. Ten new countries joined the                            EU in 2004 - Cyprus, the Czech                            Republic, Estonia, Hungary, Latvia,                            Lithuania, Malta, Poland, Slovakia, and                            Slovenia. Bulgaria and Romania joined                            in 2007 and Croatia in 2013, bringing                            the current membership to 28.                          
                            In an effort to ensure that the EU                            could function efficiently with an                            expanded membership, the Treaty of Nice                            (signed in 2000) set forth rules aimed                            at streamlining the size and procedures                            of EU institutions. An effort to                            establish a "Constitution for Europe,"                            growing out of a Convention held in                            2002-2003, foundered when it was                            rejected in referenda in France and the                            Netherlands in 2005. A subsequent                            effort in 2007 incorporated many of the                            features of the rejected Constitution                            while also making a number of                            substantive and symbolic changes. The                            new treaty, initially known as the                            Reform Treaty but subsequently referred                            to as the Treaty of Lisbon, sought to                            amend existing treaties rather than                            replace them. The treaty was approved                            at the EU intergovernmental conference                            of the 27 member states held in Lisbon                            in December 2007, after which the                            process of national ratifications                            began. In October 2009, an Irish                            referendum approved the Lisbon Treaty                            (overturning a previous rejection) and                            cleared the way for an ultimate                            unanimous endorsement. Poland and the                            Czech Republic signed on soon after.                            The Lisbon Treaty, again invoking the                            idea of an "ever closer union," came                            into force on 1 December 2009 and the                            European Union officially replaced and                            succeeded the European Community.                          
                            The evolution of what is today the                            European Union (EU) from a regional                            economic agreement among six                            neighboring states in 1951 to today's                            hybrid intergovernmental and                            supranational organization of 28                            countries across the European continent                            stands as an unprecedented phenomenon                            in the annals of history. Dynastic                            unions for territorial consolidation                            were long the norm in Europe; on a few                            occasions even country-level unions                            were arranged - the Polish-Lithuanian                            Commonwealth and the Austro-Hungarian                            Empire were examples. But for such a                            large number of nation-states to cede                            some of their sovereignty to an                            overarching entity is unique.                          
                            Although the EU is not a federation in                            the strict sense, it is far more than a                            free-trade association such as ASEAN,                            NAFTA, or Mercosur, and it has certain                            attributes associated with independent                            nations: its own flag, currency (for                            some members), and law-making                            abilities, as well as diplomatic                            representation and a common foreign and                            security policy in its dealings with                            external partners.                          
                            Thus, inclusion of basic intelligence                            on the EU has been deemed appropriate                            as a new, separate entity in The World                            Factbook. However, because of the EU's                            special status, this description is                            placed after the regular country                            entries.
