UEFA represents the national football associations of Europe, runs nation and club competitions including the UEFA European Championship , UEFA Nations League , UEFA Champions League , UEFA Europa League , and
UEFA Super Cup , and controls the prize money, regulations, and media rights to those competitions.
UEFA was founded 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, 6 other associations which were not present were still recognised as founding members, bringing the total of founding associations to 31.  That number doubled by the early 1990s as new associations were born out of the fragmentation of the Soviet Union, Yugoslavia and Czechoslovakia into their constituent states. Until 1959 the main headquarters were located in Paris, and later in Bern. In 1995, UEFA headquarters were transferred to Nyon, Switzerland.
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 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 Northern Ireland, Scotland, England and Wales ( countries of the United Kingdom ), Gibraltar ( British Overseas Territory), the Faroe Islands (constituent country within the Kingdom of Denmark), and Kosovo ( state with limited recognition ), however in the context of these countries government functions concerning sport tend to be carried at the territorial level coterminous with the UEFA member entity. UEFA have the power to ban any club in Europe and they have band Turkish club Trabzonspor
Turkish Super Lig leaders, Trabzonspor has been handed a one year ban by the Union of European Football Associations (UEFA) for breaching its Financial Fair Play regulations.
The European football governing body said this on Wednesday June 3 in a statement which revealed that the Turkish club “failed to be break-even compliant as required by a settlement agreement, which it entered into on 20 May 2016”.
The ban would be applied if the club qualifies for European soccer next season or in 2021-22, but would not be implemented after that. The statement reads in part;
“On 5 July 2019, the UEFA Club Financial Control Body (CFCB) Adjudicatory Chamber determined that Trabzonspor A? (TUR) failed to be break-even compliant as required by a settlement agreement, which it entered into on 20 May 2016 and sanctioned the club with a conditional exclusion from participating in one (1) UEFA club competition for which it would otherwise qualify in the 2020/21 and 2021/22 seasons,” UEFA said in a statement.
“The sanction would not take effect if the club fulfilled certain conditions, including meeting a target with respect to its financial results for the 2019 financial year.
“The CFCB Adjudicatory Chamber has now determined that Trabzonspor A? failed to meet the target fixed for the 2019 financial year.
“As a result, the CFCB Adjudicatory Chamber has ordered that the club be excluded from participating in one (1) UEFA club competition for which it would otherwise qualify in the 2020/21 and 2021/22 seasons.”
