There are two large metropolitan areas in Spain: Barcelona and Madrid. While Madrid, with a population of 6.5 million, sits in third place in Europe, after London and Paris, Barcelona is in sixth place, with nearly 5 million. The two are global capitals and compete primarily in a European and international arena, although the tensions between them can be seen as drivers of the current political-territorial dispute in Spain.
