Introduction

Barcelona, also known as Barca, is a professional football club, based in Barcelona, Catalonia, Spain. It is also one of the most successful clubs in European and international club football, having won four UEFA Champions League, a record four UEFA Cup Winners' Cup, four UEFA Super Cup and one FIFA Club World Cup trophies. They also won a record three Inter-Cities Fairs Cup trophies, considered the predecessor to the UEFA Cup.

It is the only European club to have played continental football every season since 1955, and one of the only three clubs to have never been relegated from La Liga, along with Athletic Bilbao and Real Madrid. In 2009, Barcelona became the first club in Spain to win the treble consisting of La Liga, Copa del Rey, and the Champions League.

Founded as Foot-Ball Club Barcelona in 1899 by a group of Swiss, English and Catalan footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Mes que un club". The official Barca anthem is the "Cant del Barca" written by Jaume Picas and Josep Maria Espinas. Unlike many other football clubs, the supporters own and operate Barcelona. It is the world's second richest football club in terms of revenue, with an annual turnover of 398 million euros.
