Swansea City Association Football Club (Welsh: Clwb Pêl-droed Dinas Abertawe) is a Welsh professional football club based in the city of Swansea, south Wales that play in the Premier League. They play their home matches at the Liberty Stadium. The club was founded in 1912 as Swansea Town and joined the Football League in 1921. The club changed their name in 1969, when it adopted the name Swansea City to reflect Swansea's new status as a city.
In 1981, the club were promoted to the original Football League First Division. It was during the following season they came close to winning the league title, but a decline then set near the season's end before finishing sixth, although a club record. It was from here the club suffered a relegation the season after, returning to the Football League Fourth Division a few seasons later, then narrowly avoided relegation to the Football Conference in 2003. Prior to playing home matches at the Liberty Stadium, the team had previously hosted at the Vetch Field. The Swansea City Supporters Society Ltd owns 20% of the club,with their involvement hailed by Supporters Direct as "the most high profile example of the involvement of a supporters' trust in the direct running of a club".
In 2011, Swansea were promoted to the Premier League, becoming the first Welsh team to play in the division since its formation in 1992. On 24 February 2013, Swansea beat Bradford City 5–0 to win the 2012–13 Football League Cup (the competition's highest ever winning margin for the final), winning the first major trophy in the club's history and qualifying the Swans for the 2013–14 UEFA Europa League.
