Because the EU is an organisation of many countries.
There could be many answers to that. Here are just two: It is a trading bloc. It is a supranational organisation.
A unified Europe, economically and politically. Eventually, the European Union will most likely fuse into one nation on account of it being a supranational organization (acting somewhat as a country already).
The European Union is a supranational organization in Europe, bonding its members economically and politically. EUR is the abbreviation for the currency of the European Union, the Euro. Three countries in the EU that use the Euro include Germany, France, and Italy.
The European Union is not a region. It is an organisation, that has countries as members. It is not a geographic entity. See the related question.
It established the European Economic Community and Euratom, which were important supranational agreements both economically and politically. It laid the foundations for the European Union as we know it now with its familiar institutions.
There is no union between them. The United Kingdom is part of the continent of Europe, on a number of islands on its west coast. The United Kingdom is a member of the European Union, a supranational organization containing over half of all European countries. All of the countries are independent.
Confederation was kinda a alliance name and it is a alliance for other countries to join
Yes. It is an organisation that has countries, not people as members. It is sometimes described as being a supranational organisation. It currently has 28 member nations.
Not really. Although the Benelux Union was formed in 1944, it was not until 1955 that supranationalism was present, when a Benelux Parliament was formed. The European Coal and Steel Community was formed in 1952. When the ECSC was formed, it had several aims, one of which was to become the first supranational organization in the world, which it did, as the Benelux Union was not yet supranational.
The European Union has multiple objectives as a supranational form of governance. These include diminishing the likelihood of conflict by finalizing the border questions, economic integration, eliminating inter-European migration and labor barriers, and moving towards common foreign and monetary policies.
It was the best way to put together a strong united and competitive economic entity.
