Barcelona holds a long-standing rivalry with Real Madrid, with matches between the two teams referred to as "El Clásico". Unlike many other football clubs, the fans of FC Barcelona own and operate the club. The club is the world's second richest football club (€365m) in terms of revenue, only surpassed by Real Madrid.

FC Barcelona is one of only three clubs never to have been relegated from La Liga and the most successful club in Spanish football after Real Madrid, having won nineteen La Liga titles, a record twenty-five Spanish Cups, eight Spanish Super Cups, four Eva Duarte Cups and two League Cups. They are also one of the most successful clubs in European football having won fourteen official major trophies in total, including ten UEFA competitions.[1] They have won three UEFA Champions League titles, a record four UEFA Cup Winners' Cups, a record three Inter-Cities Fairs Cups (the forerunner to the UEFA Europa League), three UEFA Super Cups and one FIFA Club World Cup. In 2009, Barcelona became the first club in Spain to win the treble of La Liga, Copa del Rey and Champions League. The club is also the only European side to have played continental football in every season since its inception in 1955. FC Barcelona became the first football team ever to win six out of six competitions in a single year thus completing the sextuple, comprising the 2008–09 La Liga, 2008–09 Copa del Rey, 2009 Supercopa de España, 2008–09 UEFA Champions League, 2009 UEFA Super Cup and 2009 FIFA Club World Cup.

Futbol Club Barcelona (Catalan pronunciation: [fudˈbɔɫ ˌklup bəɾsəˈlonə], Spanish: [ˈfuðβol ˌkluβ barθeˈlona]), also known simply as Barcelona and familiarly as Barça (Catalan: [ˈbaɾsə], Spanish: [ˈbarsa]), is a football club based in Barcelona, Catalonia, Spain. The team was founded in 1899 by a group of Swiss, English and Spanish men led by Joan Gamper. The club has become a Catalan institution, hence the motto "Més que un club" (More than a club). The official Barça anthem is El Cant del Barça by Josep Maria Espinàs.
