European Economic Community in the context of "Schengen Convention"

The European Union (EU) has expanded a number of times throughout its history by way of the accession of new member states to the Union. To join the EU, a state needs to fulfil economic and political conditions called the Copenhagen criteria (named after the Copenhagen summit in June 1993), which require a stable democratic government that respects the rule of law, and its corresponding freedoms and institutions. According to the Maastricht Treaty, each current member state and the European Parliament must agree to any enlargement. The process of enlargement is sometimes referred to as European integration. This term is also used to refer to the intensification of co-operation between EU member states as national governments allow for the gradual harmonisation of national laws.

The EU's predecessor, the European Economic Community, was founded with the Inner Six member states in 1958, when the Treaty of Rome came into force. Since then, the EU's membership has grown to twenty-seven, with the latest member state being Croatia, which joined in July 2013. The most recent territorial enlargement of the EU was the incorporation of Mayotte in 2014. Campione d'Italia joined the EU Customs Union in 2020. The most notable territorial reductions of the EU, and its predecessors, have been the exit of Algeria upon independence in 1962, the exit of Greenland in 1985, and the withdrawal of the United Kingdom in 2020.

The European Free Trade Association (EFTA) is a regional trade organisation and free trade area consisting of four European states: Iceland, Liechtenstein, Norway and Switzerland. The organisation operates in parallel with the European Union (EU), and all four member states participate in the European single market and are part of the Schengen Area. They are not, however, party to the European Union Customs Union.

EFTA was historically one of the two dominant western European trade blocs, but is now much smaller and closely associated with its historical competitor, the European Union. It was established on 3 May 1960 to serve as an alternative trade bloc for those European states that were unable or unwilling to join the then European Economic Community (EEC), the main predecessor of the EU. The Stockholm Convention (1960), to establish the EFTA, was signed on 4 January 1960 in the Swedish capital by seven countries (known as the "Outer Seven": Austria, Denmark, Norway, Portugal, Sweden, Switzerland and the United Kingdom). A revised Convention, the Vaduz Convention, was signed on 21 June 2001 and entered into force on 1 June 2002.

A democratic deficit (or democracy deficit) occurs when ostensibly-democratic organizations or institutions (particularly governments) fall short of fulfilling the principles of democracy in their practices or operation. Representative and linked parliamentary integrity have become widely discussed. The qualitative expression of the democratic deficit is the difference between the democracy indices of a country from the highest possible values.

The phrase "democratic deficit" is cited as first being used by the Young European Federalists in their Manifesto in 1977, which was drafted by Richard Corbett.It was also used by David Marquand in 1979, referring to the European Economic Community, the forerunner of the European Union.

The Treaty of Rome, or EEC Treaty (officially the Treaty establishing the European Economic Community), brought about the creation of the European Economic Community (EEC), the best known of the European Communities (EC). The treaty was signed on 25 March 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany, and it came into force on 1 January 1958. Originally the "Treaty establishing the European Economic Community", and now continuing under the name "Treaty on the Functioning of the European Union", it remains one of the two most important treaties in what is now the European Union (EU).

The treaty proposed the progressive reduction of customs duties and the establishment of a customs union. It proposed to create a common market for goods, labour, services, and capital across member states. It also proposed the creation of a Common Agriculture Policy, a Common Transport Policy and a European Social Fund and established the European Commission.

The Schengen Agreement (English: /ˈʃɛŋən/ SHENG-ən, Luxembourgish: [ˈʃæŋən] ) is a treaty which led to the creation of Europe's Schengen Area, in which internal border checks have largely been abolished. It was signed on 14 June 1985, near the town of Schengen, Luxembourg, by five of the ten member states of the then European Economic Community. It proposed measures intended to gradually abolish border checks at the signatories' common borders, including reduced-speed vehicle checks which allowed vehicles to cross borders without stopping, allowing residents in border areas freedom to cross borders away from fixed checkpoints, and the harmonisation of visa policies.

In 1990, the Agreement was supplemented by the Schengen Convention which proposed the complete abolition of systematic internal border controls and a common visa policy. The Schengen Area operates very much like a single state for international travel purposes with external border controls for travellers entering and exiting the area, and common visas, but with no internal border controls. It currently consists of 29 European countries covering a population of over 450 million people and an area of 4,595,131 square kilometres (1,774,190 sq mi).

The Treaty on the Functioning of the European Union (TFEU) is one of two treaties forming the constitutional basis of the European Union (EU), the other being the Treaty on European Union (TEU). It was previously known as the Treaty Establishing the European Community (TEC).

The Treaty originated as the Treaty of Rome (fully the Treaty establishing the European Economic Community), which brought about the creation of the European Economic Community (EEC), the best-known of the European Communities (EC). It was signed on 25 March 1957 by Belgium, France, Italy, Luxembourg, the Netherlands and West Germany and came into force on 1 January 1958. It remains one of the two most important treaties in the modern-day European Union (EU).

A European Union Association Agreement or simply Association Agreement (AA) is a treaty between the European Union (EU, or its predecessors), its Member States and a non-EU country or bloc of countries that governs bilateral relations. Areas frequently covered by such agreements include the development of political, trade, social, cultural and security links. The provision for an association agreement was included in the Treaty of Rome, which established the European Economic Community, as a means to enable co-operation of the Community with the United Kingdom, which had retreated from the treaty negotiations at the Messina Conference of 1955. According to the European External Action Service, for an agreement to be classified as an AA, it must meet several criteria:

The EU typically concludes Association Agreements in exchange for commitments to political, economic, trade, or human rights reform in a country. In exchange, the country may be offered tariff-free access to some or all EU markets (industrial goods, agricultural products, etc.), and financial or technical assistance. Most recently signed AAs also include a Free Trade Agreement (FTA) between the EU and the external party.
