Madrid

The primitive core of Madrid, a walled military outpost, dates back to the late 9th century, under the Emirate of Córdoba. Conquered by Christians in 1083 or 1085, it consolidated in the Late Middle Ages as a sizeable town of the Crown of Castile. The development of Madrid as an administrative centre was fostered after 1561, as it became the permanent seat of the court of the Hispanic Monarchy. The following centuries were characterised by the reinforcement of Madrid's status within the framework of a centralised form of state-building.

The Madrid urban agglomeration has the second-largest GDP in the European Union. Madrid is ranked as an alpha world city by the Globalization and World Cities Research Network. The metropolitan area hosts major Spanish companies such as Telefónica, Iberia, BBVA and FCC. It concentrates the bulk of banking operations in Spain and it is the Spanish-speaking city generating the largest number of webpages.
