Enlargement of the European Union

The following is an example of an accession process—Estonia's path to membership from the 2004 enlargement. Ease of accession depends on the state: how integrated it is with the EU beforehand, the state of its economy and public institutions, any outstanding political issues with the EU and (historically) how much law to date the EU has built up that the acceding state must adopt. This outline also includes integration steps taken by the accession country after it attains membership.

The European Coal and Steel Community (ECSC) was proposed by Robert Schuman in his declaration on 9 May 1950 and involved the pooling of the coal and steel industries of France and West Germany.[37] Half of the project states, Belgium, Luxembourg, and the Netherlands, had already achieved a great degree of integration amongst themselves with the organs of Benelux and earlier bilateral agreements. These five countries were joined by Italy and they all signed the Treaty of Paris on 23 July 1952. These six members, dubbed the 'inner six' (as opposed to the 'outer seven' who formed the European Free Trade Association who were suspicious of such plans for integration) went on to sign the Treaties of Rome establishing two further communities, together known as the European Communities when they merged their executives in 1967.

In 1962, Spain, ruled by the military dictator Francisco Franco, issued its first attempt to join the European Communities. Spanish Foreign Affairs minister Fernando María Castiella sent the request form to French Prime Minister Maurice Couve de Murville.[38] This request was rejected by all the member countries in 1964; Spain was not a democracy at the time, and thus unable to enter the EEC.[39]

The Community did see some loss of territory due to the decolonialisation occurring in their era. Algeria, which was an integral part of France, had a special relationship with the Community.[40] Algeria gained independence on 5 July 1962 and hence left the Community. There was no enlargement until the 1970s.

The United Kingdom, which had refused to join as a founding member, changed its policy following the Suez crisis and applied to be a member of the Communities. Other EEC members were also inclined to British membership on those grounds. French President Charles de Gaulle vetoed British membership.[15]

Once de Gaulle had left office, the door to enlargement was once again opened. The EEC economy had also slowed down and British membership was seen as a way to revitalise the community.[15] Only after a 12-hour talk between British Prime Minister Edward Heath and French President Georges Pompidou took place did Britain's third application succeed.[41] After Britain was accepted Prime Minister Edward Heath said:

"For my part, I have no doubt at all that the discussions which we have had will prove of real and lasting benefit, not only to Britain and France, but to Europe as a whole."[41]

As part of the deal for British entry, France agreed to allow the EEC its own monetary resources. However France made that concession only as Britain's small agriculture sector would ensure that Britain would be a net contributor to the Common Agricultural Policy dominated EEC budget.[15] Applying together with the UK, as on the previous occasions, were Denmark, Ireland, and Norway.[42] These countries were so economically linked to the UK that they considered it necessary to join the EEC if the UK did.[15] However the Norwegian government lost a national referendum on membership and hence did not accede with the others on 1 January 1973. Gibraltar joined the Community with the United Kingdom at this point, as can be seen in the long title of the UK European Communities Act 1972.

The next enlargement would occur for different reasons. The 1970s also saw Greece, Spain, and Portugal emerge from dictatorship. These countries desired to consolidate their new democratic systems by binding themselves into the EEC. Equally, the EEC was unsure about which way these countries were heading and wanted to ensure stability along its southern borders.[15] However François Mitterrand initially opposed their membership fearing they were not ready and it would water the community down to a free trade area.[14]

Greece joined the EU in 1981 followed by Spain and Portugal in 1986.

The year 1985, however, saw the first time a territory voted to leave the Community, when Greenland was granted home rule by Denmark and the territory used its new powers and voted to withdraw from the Community (See member state territories).

Morocco and Turkey applied for membership in 1987. Morocco's application was turned down as it was not considered European, while Turkey's application was considered eligible on the basis of the 1963 Ankara Association Agreement, but the opinion of the Commission on the possible candidate status was by then negative. Turkey received candidate status only in 1999 and began official membership negotiations in 2005, which are still in progress as of 2018.[43]

The Iron Curtain's fall enabled eastward enlargement. (Berlin Wall)

After the 1970s, Europe experienced an economic downturn which led to leaders launching of the Single European Act which set to create a single market by 1992. The effect of this was that EFTA states found it harder to export to the EEC and businesses (including large EFTA corporations such as Volvo) wished to relocate within the new single market making the downturn worse for EFTA. EFTA states began to discuss closer links with the EEC despite its domestic unpopularity.[44]

Austria, Finland, and Sweden were neutral in the Cold War so membership of an organisation developing a common foreign and security policy would be incompatible with that. With the end of the Cold War in 1989, that obstacle was removed, and the desire to pursue membership grew stronger.[44] On 3 October 1990, the reunification of East and West Germany brought East Germany into the Community without increasing the number of member states.

The Community later became the European Union in 1993 by virtue of the Maastricht Treaty, and established standards for new entrants so their suitability could be judged. These Copenhagen criteria stated in 1993 that a country must be a democracy, operate a free market, and be willing to adopt the entire body of EU law already agreed upon. Also in 1993 the European Economic Area was established with the EFTA states except Switzerland. Most of the new EEA states pursued full EU membership as the EEA did not sufficiently satisfy the needs of their export based corporations. The EU has also preferred these states to integrate via the EEA rather than full membership as the EEC wished to pursue monetary integration and did not wish for another round of enlargement to occupy their attention. However, with the EEA's credibility dented following rejection by businesses and Switzerland, the EU agreed with full membership. This was more readily accepted with the prospect of poorer countries wishing to join; contributions from richer countries would help balance the EU budget.[44] On 1 January 1995 Austria, Finland, and Sweden acceded to the EU marking its fourth enlargement. The Norwegian government lost a second national referendum on membership.

EU's enlargements in the 2000s and the 2010s:

  European Union 1 Jan. 1995 – 30 April 2004

  Joined the EU on 1 May 2004

  Joined the EU on 1 Jan. 2007

  Joined the EU on 1 July 2013

As with the Mediterranean countries in the 1980s, the countries in Central and Eastern Europe had emerged from dictatorships and wanted to consolidate their democracies. They also wanted to join the project of European integration and ensure they did not fall back into the Russian sphere of influence. The EU and NATO offered a guarantee of this, and the EU was also seen as vital to ensuring the economic success of those countries. However, the EU's desire to accept these countries' membership applications was less than rapid. The collapse of communism came quickly and was not anticipated. The EU struggled to deal with the sudden reunification of Germany with the addition of its poorer 17 million people and, while keeping its monetary union project on track, it was still at that early stage pointing the EFTA countries in the direction of the EEA rather than full membership.[45]

States in Central and Eastern Europe persisted and eventually the above-mentioned issues were cleared. The US also pressured the EU to offer membership as a temporary guarantee; it feared expanding NATO too rapidly for fear of frightening Russia. Although eventually trying to limit the number of members, and after encouragement from the US, the EU pursued talks with ten countries and a change of mind by Cyprus and Malta helped to offset slightly the influx of large poorer member states from Central and Eastern Europe.[45]

In the end, eight Central and Eastern European countries (the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Slovenia), plus two Mediterranean countries (Malta and Cyprus) were able to join on 1 May 2004. This was the largest single enlargement in terms of people, and number of countries, though not in terms of GDP.[46] The less developed nature of these countries was of concern to some of the older member states. Some countries, such as the UK, immediately opened their job market to the accession states, whereas most others placed temporary restrictions on the rights of work of the citizens of these states to their countries. The movement westward of some of the labour force of the newly acceded countries that occurred in the aftermath of the enlargement initially spawned clichés among the public opinion and media of some western countries (such as the "Polish plumber"), despite the generally conceded benefit to the economies concerned.[47] The official EU media (the speeches of the European Commission) frequently referred to the enlargement to the CEE region as "an historical opportunity" and "morally imperative", which reflected the desire of the EU to admit these countries as members, even though they were less developed than the Western European countries.[48] Following this Romania and Bulgaria, though were deemed initially as not fully ready by the Commission to join in 2004, acceded nevertheless on 1 January 2007. These, like the countries joining in 2004, faced a series of restrictions as to their citizens not fully enjoying working rights on the territory of some of the older EU members. Bulgaria and Romania are not yet members of the Schengen area; however, their citizens can travel visa-free to the other EU countries.

The socio-economic research on the attitudes towards the integration from both hosting and visiting countries has revealed divergent views. The analysis shows, there are a number of possible factors of the rationalization and understanding of the practices on what the enlargement has been and should be like. Attitudes of even skeptical citizens, do not discard the possibility on future sustainable enlargements. The years subsequent to the EU accession will lead to extensive dialogues between policy-makers, governments, and European citizens about the path for a constructive development.[49]

The 2003 European Council summit in Thessaloniki set integration of the Western Balkans as a priority of EU expansion. The EU's relations with the Western Balkans states were moved from the "External Relations" to the "Enlargement" policy segment in 2005. Those states which have not been recognised as candidate countries are considered "potential candidate countries".[50] The move to Enlargement directorate was a consequence of the advancement of the Stabilisation and Association process.

Croatia joined on 1 July 2013, following ratification of the 2011 Accession Treaty by all other EU countries. Albania and the several successor states of the Socialist Federal Republic of Yugoslavia have all adopted EU integration as an aim of foreign policy.
