European Union Preliminary statement

Preliminary statement: The evolution of the European Union (EU) from a regional economic agreement among six neighboring states in 1951 to today's supranational organization of 27 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 truly 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 many of the attributes associated with independent nations: its own flag, anthem, founding date, and currency, as well as an incipient common foreign and security policy in its dealings with other nations.
In the future, many of these nation-like characteristics are likely to be expanded. 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.
