Until 1714, Spain was a loose confederation of kingdoms and statelets, under the same king, until King Philip V removed the autonomous status of the Aragonese crown. Moreover, the creation of a unified state in the 19th and 20th centuries has lead to the present situation, apparently simple, but sometimes extremely confusing. During the Second Spanish Republic (1931-1936), the Basque and Catalan were given limited self-government, which was lost after the Spanish Civil War (1936-1939) and restored in 1978 during the transition to democracy.
With the approval of the Spanish Constitution of 1978 and the arrival of democracy, the old historic nationalities — Basque Country, Catalonia, Galicia and Andalusia— were given far-reaching autonomy, which was then soon extended to all Spanish regions, resulting in one of the most decentralized territorial organizations in Western Europe.
Madrid is home to Real Madrid, the world's most successful football club (according to FIFA). There are three other major teams, the Primera Division club Atlético de Madrid, Getafe Club de Futbol and Rayo Vallecano.
The crown jewel of Spain's next decade of infrastructure construction is the Spanish high speed rail network, Alta Velocidad Española AVE. Currently, an ambitious plan includes the construction of a 7000 km network, centered naturally on Madrid. The overall goal is to have all important provincial cities be no more than 4 hours away from Madrid, and no more than 6 hours away from Barcelona. Currently, AVE high-speed trains link Atocha station to Seville in the south and Lleida in the east (to be extended to Barcelona).
Mainland Spain is dominated by high plateaus and mountain ranges such as the Pyrenees or the Sierra Nevada. Running from these heights are several major rivers such as the Tajo, the Ebro, the Duero, the Guadiana and the Guadalquivir. Alluvial plains are found along the coast, the largest of which is that of the Guadalquivir in Andalusia, in the east there are alluvial plains with medium rivers like Segura, Júcar and Turia. Spain is bound to the east by Mediterranean Sea (containing the Balearic Islands), to the north by the Bay of Biscay and to its west by the Atlantic Ocean, where the Canary Islands off the African coast are found.
The Napoleonic invasion gave the opportunity to the American colonies, led by Libertadores, to claim their independence. Between 1810 and 1824, Chile, Colombia, Ecuador, Venezuela, and the other colonies declared and won their independence. The only New World colonies Spain was left with were the islands of Cuba and Puerto Rico. The Allies fought Napoleon's forces in the Peninsular War, with Joseph Bonaparte ruling as king at Madrid. In 1812 the Cortes took refuge at Cádiz and created the first modern Spanish constitution, the Constitution of 1812 (informally named La Pepa).
The most well-known variety of Spanish folk music is likely flamenco, a diverse genre created by Andalusian Roma. Flamenco is known since at least the 1770s, and has been through several cycles of dwindling popularity and rebirth. The style has produced many of the most famous Spanish musicians, including singer Camarón de la Isla and guitarist Carlos Montoya. Outside of flamenco, regional Spanish folk music includes the distinct Basque trikitrixa and accordion music, Galician and Asturian gaita (bagpipe) and Aragonese jota. Though some folk traditions have died out or are moribund, some retain great popularity and have been modernized and adapted to new instruments, styles and formats. These include the popular Celtic music of Galicia, the singer-songwriter tradition of nova canço and New Flamenco.
