EU Competences

The European Union (EU) is a supranational political and economic union of member states that are located primarily in Europe. The union has a total area of and an estimated total population of about 447million. The EU has often been described as a '' sui generis'' political entity (without precedent or comparison) combining the characteristics of both a federation and a confederation.

Containing 5.8per cent of the world population in 2020, the EU generated a nominal gross domestic product (GDP) of around trillion in 2021, constituting approximately 18per cent of global nominal GDP. Additionally, all EU states but Bulgaria have a very high Human Development Index according to the United Nations Development Programme. Its cornerstone, the Customs Union, paved the way to establishing an internal single market based on standardised legal framework and legislation that applies in all member states in those matters, and only those matters, where the states have agreed to act as one. EU policies aim to ensure the free movement of people, goods, services and capital within the internal market;
enact legislation in justice and home affairs; and maintain common policies on trade, agriculture, fisheries and regional development. Passport controls have been abolished for travel within the Schengen Area. The eurozone is a group composed of the 19 EU member states that have fully implemented the economic and monetary union and use the euro currency. Through the Common Foreign and Security Policy, the union has developed a role in external relations and defence. It maintains permanent diplomatic missions throughout the world and represents itself at the United Nations, the World Trade Organization, the G7 and the G20. Due to its global influence, the European Union has been described by some scholars as an emerging superpower.

The union was established along with its citizenship when the Maastricht Treaty came into force in 1993, and was subsequently incorporated as an international law juridical person upon entry into force of the Treaty of Lisbon in 2009, but its beginnings may be traced to its earliest predecessors incorporated primarily by a group of founding states known as the Inner Six (Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany) at the start of modern institutionalised European integration in 1948 and onwards, namely to the Western Union (WU, 1954 renamed Western European Union, WEU), the International Authority for the Ruhr (IAR), the European Coal and Steel Community (ECSC), the European Economic Community (EEC, 1993 renamed European Community, EC) and the European Atomic Energy Community (Euratom), established, respectively, by the 1948 Treaty of Brussels, the 1948 London Six-Power Conference, the 1951 Treaty of Paris, the 1957 Treaty of Rome and the 1957 Euratom Treaty. These increasingly amalgamated bodies later known collectively as the European Communities have grown since, along with their legal successor, the EU, both in size through accessions of further 21 states as well as in power through acquisitions of various policy areas to their remit by the virtue of the abovementioned treaties, as well as numerous other ones, such as the Modified Brussels Treaty, the Merger Treaty, the Single European Act, the Treaty of Amsterdam and the Treaty of Nice. In 2012, the EU was awarded the Nobel Peace Prize.

After the creation by six states, 22 other states joined the union in 1973–2013. The United Kingdom became the only member state to leave the EU in 2020, ten countries are aspiring or negotiating to join it.

History

Origins

After the First World War, but particularly with Second World War, internationalism was gaining, with the creation of the Bretton Woods System in 1944, the United Nations in 1945 and the French Union (19461958), the latter directing decolonization by possibly integrating its colonies into a European community. In this light European integration was seen, already during the war, as an antidote to the extreme nationalism which had devastated parts of the continent.

The Ventotene prison Manifesto of 1941 by Altiero Spinelli propagated European integration through the Italian Resistance and after 1943 through the European Federalist Movement. Winston Churchill called in 1943 for a post-war "Council of Europe" and on 19 September 1946, at the University of Zürich, coincidentally parallel to the Hertenstein Congress of the Union of European Federalists, for a United States of Europe. Richard von Coudenhove-Kalergi, who successfully established during the interwar period the oldest organization for European integration, the Paneuropean Union, founded in June 1947 the European Parliamentary Union (EPU).

Towards the end of World War II, the Three Allied Powers discussed during the Tehran Conference and the ensuing 1943 Moscow Conference the plans to establish joint institutions. This led to a decision at the Yalta Conference in 1944 to include Free France as the Fourth Allied Power and to form a European Advisory Commission, later replaced by the Council of Foreign Ministers and the Allied Control Council, following the German surrender and the Potsdam Agreement in 1945.

The growing rift among the Four Powers became evident as a result of the rigged 1947 Polish legislative election which constituted an open breach of the Yalta Agreement, followed by the announcement of the Truman Doctrine on 12 March 1947. On 4 March 1947 France and the United Kingdom signed the Treaty of Dunkirk for mutual assistance in the event of future military aggression in the aftermath of World War II against any of the pair. The rationale for the treaty was the threat of a potential future military attack, specifically a Soviet one in practice, though publicised under the disguise of a German one, according to the official statements. Immediately following the February 1948 coup d'état by the Communist Party of Czechoslovakia, the London Six-Power Conference was held, resulting in the Soviet boycott of the Allied Control Council and its incapacitation, an event marking the beginning of the Cold War. The remainder of the year 1948 marked the beginning of the institutionalised modern European integration.

Initial years and the Paris Treaty (19481957)

The year 1948 marked the beginning of the institutionalised modern European integration. In March 1948 the Treaty of Brussels was signed, establishing the Western Union (WU), followed by the International Authority for the Ruhr. Furthermore, the Organization for European Economic Co-operation (OEEC), the predecessor of the OECD, was also founded in 1948 to manage the Marshall Plan, triggering as a Soviet response formation of the Comecon. The ensuing Hague Congress of May 1948 was a pivotal moment in European integration, as it led to the creation of the European Movement International, the College of Europe and most importantly to the foundation of the Council of Europe on 5 May 1949 (today its Europe day). The Council of Europe was one of the first institutions to bring the sovereign nations of (then only Western) Europe together, raising great hopes and fevered debates in the following two years for further European integration. It has since been a broad forum to further cooperation and shared issues, achieving for example the European Convention on Human Rights in 1950. Essential for the actual birth of the institutions of the EU was the Schuman Declaration on 9 May 1950 (the day after the fifth Victory in Europe Day) and the decision by six nations (France, Belgium, Netherlands, Luxembourg, West Germany and Italy) to follow Schuman and draft the Treaty of Paris. This treaty created in 1952 the European Coal and Steel Community (ECSC), which was built on the International Authority for the Ruhr, installed by the Western Allies in 1949 to regulate the coal and steel industries of the Ruhr area in West Germany. Backed by the Marshall Plan with large funds coming from the United States since 1948, the ECSC became a milestone organization, enabling European economic development and integration and being the origin of the main institutions of the EU such as the European Commission and Parliament. Founding fathers of the European Union understood that coal and steel were the two industries essential for waging war, and believed that by tying their national industries together, a future war between their nations became much less likely.
In parallel with Schuman, the Pleven Plan of 1951 tried but failed to tie the institutions of the developing European community under the European Political Community, which was to include the also proposed European Defence Community, an alternative to West Germany joining NATO which was established in 1949 under the Truman Doctrine. In 1954 the Modified Brussels Treaty transformed the Western Union into the Western European Union (WEU). West Germany eventually joined in 1955 both WEU and NATO, prompting the Soviet Union to form the Warsaw Pact in 1955 as an institutional framework for its military dominatin in the countries of Central and Eastern Europe. Assessing the progress of European integration the Messina Conference was held in 1955, ordering the Spaak report, which in 1956 recommended the next significant steps of European integration.

Treaty of Rome (19581972)

In 1957, Belgium, France, Italy, Luxembourg, the Netherlands, and West Germany signed the Treaty of Rome, which created the European Economic Community (EEC) and established a customs union. They also signed another pact creating the European Atomic Energy Community (Euratom) for co-operation in developing nuclear power. Both treaties came into force in 1958. Although the EEC and Euratom were created separately from the ECSC, they shared the same courts, and the Common Assembly. The EEC was headed by Walter Hallstein (Hallstein Commission) and Euratom was headed by Louis Armand (Armand Commission) and then Étienne Hirsch (Hirsch Commission). The OEEC was in turn reformed in 1961 into the Organisation for Economic Co-operation and Development (OECD) and its membership was extended to non-European states, the US and Canada. During the 1960s, tensions began to show, with France seeking to limit supranational power. Nevertheless, in 1965 an agreement was reached, and on 1 July 1967 the Merger Treaty created a single set of institutions for the three communities, which were collectively referred to as the ''European Communities''. Jean Rey presided over the first merged commission (Rey Commission).

First enlargement, and European co-operation (19731993)

In 1973, the communities were enlarged
