What is the nature of the EU as a political entity?

As a political entity the EU has evolved massively over time, beginning with a series of treaties and the creation of the'European coal and steel community' (ECSC) by five member states. A few years later the European community was created by the merging of the ECSC with the EEC (European economic community) and Euratom (European atomic energy community). At this point the 'EU' was little more than a loosely made community, and a first attempt at economic integration in Europe. More member states continued to join the EC, and in the late 80s it began to expand into a monetary union. It did this through SEA (single European act) which prepared for the establishment of a common market, as well as well as the Maastrict treaty which made the EC into an official institution (the EU), and further paved the way for the creation of a single currency. National currencies were replaced with the Euro in 2002 for some member states, while others such as the UK chose to opt out. At this point the EU had evolved from a first attempt at economic integration to a fully fledged institution with international law making abilities. The next step was to create a constitution however this failed in 2004 when referendums in France and the Netherlands indicated the public were not in favour of its ratification. Instead, the Lisbon treaty was created, implementing many of the constitutions changes in the form of amendments to existing treaties. This came into force in December 2009.

As a result of widening and deepening integration, the EU has been seen by some as a European superstate, going further than the idea of  federalised Europe and ultimately destroying state sovereignty. Such people also view the EU as a rival superpower to the US, in terms of its economic and potential military power. While I would argue that the EU is no longer the intergovernmental institution of independent states that it once was, I would disagree with the idea that the EU has become a superstate. The sovereignty of member states is enshrined in the Luxembourg compromise of 1966, which gave each member state a veto on matters threatening vital national interests. However, it cannot be ignored that the ability of the EU to create laws that its member states must abide to does erode some state sovereignty, as does the introduction of qualified majority voting.

Despite the increasing centralisation within the EU there are checks in place to ensure it cannot be described as truly 'federal' - it is more accurate to talk of a federalising Europe. An example of this is the principle of subsidiarity, which ensures decisions are made as close to citizens as possible, essentially devolving power from the centre outwards.

The current nature of the EU as a political entity is an institution of economic, (and to a lesser extent, political) governance. While it is no longer confined to intergovernmentalism, it cannot be said to be a purely supranational body and as such is a blend of the two. It extends far beyond other intergovernmental institutions in that European citizens have free movement (as a result of the Schengen agreement) and many share the euro as their currency, but does not go as far as to completely erode state sovereignty or to have a common security and defence policy. While the EU has become more than the confederation of independent states it once was, it has not and may never become the 'united states of Europe' as visualised by Churchill.
