UEFA

UEFA was officially inaugurated on 15 June 1954 in Basel, Switzerland, after consultation between the Italian, French, and Belgian associations. At the founding meeting, 25 members were present. However, six other associations which were not present were still recognised as founding members, bringing the total of founding associations to 31. UEFA grew to more than 50 members by the mid-1990s, as new associations were born out of the fragmentation of the Soviet Union, Yugoslavia and Czechoslovakia into their constituent states. UEFA's main headquarters after its foundation were located in Paris, but moved to Bern in 1960. Finally, they moved to Nyon, Switzerland, in 1995, opening the organisation's current headquarters in 1999.

UEFA membership coincides for the most part with recognition as a sovereign country in Europe (48 out of 55 members are sovereign UN member states), although there are some exceptions. One UN member state (Monaco) and one UN General Assembly non-member observer state (Vatican City) are not members. Some UEFA members are not sovereign states, but form part of a larger recognised sovereign state in the context of international law. These include England, Northern Ireland, Scotland, and Wales (UK constituent countries); Gibraltar (UK overseas territory); Faroe Islands (Danish Realm); and Kosovo (state with limited recognition). In the context of these countries, sports governance tends to be carried out at the territorial level coterminous with the UEFA member entity. However, UEFA has declined membership to other polities like Jersey.

Some UEFA members are transcontinental states (Azerbaijan, Georgia, Kazakhstan, Russia, and Turkey), and others are considered part of Europe both culturally and politically (Turkey, Cyprus, and Armenia). Countries which had been members of the Asian Football Confederation (AFC) were also admitted to the European Football Association, such as Israel (because it had been banned from the AFC group in 1974) and Kazakhstan. …

The UEFA executive committee comprises the UEFA president and up to 19 other members: 16 elected by the UEFA Congress (including at least two female members), two by European Football Clubs and one by the European Leagues. All members hold the same rights and duties

UEFA runs official international competitions in Europe and some countries of Northern, Southwestern and Central Asia for national teams and professional clubs, known as UEFA competitions, some of which are regarded as the world's most prestigious tournaments.

UEFA is the organiser of two of the most prestigious competitions in international football: The UEFA European Championship and the UEFA Nations League. The main competition for men's national teams is the UEFA European Championship (also known as the Euro), which started in 1958, with the first finals in 1960, and was known as the European Nations Cup until 1964. The UEFA Nations League is the second tournament of UEFA and was introduced in 2018. The tournament largely replaced the international friendly matches previously played on the FIFA International Match Calendar. It will be played every two years.

UEFA also runs national competitions at Under-21, Under-19 and Under-17 levels. For women's national teams, UEFA operates the UEFA Women's Championship for senior national sides as well as Women's Under-19 and Women's Under-17 Championships.

Beside continental European competitions for national and their junior teams, the UEFA organises various qualification male and female tournaments among European national and their junior teams for World Cups (organised by FIFA) and Olympics (organised by IOC).

UEFA also organised the UEFA–CAF Meridian Cup with CAF for youth teams in an effort to boost youth football. UEFA launched the UEFA Regions' Cup, for semi-professional teams representing their local region, in 1999. In futsal there is the UEFA Futsal Championship and UEFA Under-19 Futsal Championship. Despite the existence of UEFA's Futsal and Beach soccer committee, UEFA does not organise any beach soccer competitions. …
