Context:
There is often a fierce rivalry between the two strongest teams in a national league, and this is particularly the case in La Liga, where the game between Barcelona and Real Madrid is known as El Clásico. From the start of national competitions the clubs were seen as representatives of two rival regions in Spain: Catalonia and Castile, as well as of the two cities. The rivalry reflects what many regard as the political and cultural tensions felt between Catalans and the Castilians, seen by one author as a re-enactment of the Spanish Civil War.
