Spain remained officially neutral in World Wars I and II, but suffered through a devastating Civil War (1936-39). During Franco's rule, Spain remained largely economically and culturally isolated from the outside world, but slowly began to catch up economically with its European neighbors. Under Franco, Spain actively sought the return of Gibraltar by the UK, and gained some support for its cause at the United Nations. During the 1960s, Spain began imposing restrictions on Gibraltar, culminating in the closure of the border in 1969. It was not fully reopened until 1985.
On February 20th 2005, Spain became the first country to allow its people to vote on the European Union constitution that was signed in October 2004. The rules states that if any country rejects the constitution then the constitution will be declared void. The final result was very strongly in affirmation of the constitution, making Spain the first and so far only country to approve the constitution via referendum.
Spain's natural surroundings have helped shape the culture of the nation. The success of the Basques in maintaining a separate culture over a period of millennia has doubtless been aided by the mountainous geography of their region. Several separate parts of Spain have strong maritime traditions, including inland ports on rivers: Seville, for example, was a major port until the Guadalquivir silted up. Since the availalability of mass air transport, Spain's Mediterranean beaches, especially those along the Costa del Sol, have drawn millions of tourists, providing considerable revenue (and enormous contact with the outside world) to a long-depressed and isolated area of the country.
The Romans arrived in the Iberian peninsula during the Second Punic war in the 2nd century B.C., and annexed it under Augustus after two centuries of war with the Celtic and Iberian tribes and the Phoenician, Greek and Carthaginian colonies becoming the province of Hispania. Some of Spain's present languages, religion, and laws originate from this Roman period.
The original peoples of the Iberian peninsula (in the sense that they are not known to have come from elsewhere), consisting of a number of separate tribes, are given the generic name of Iberians. This may have included the Basques, the only pre-Celtic people in Iberia surviving to the present day as a separate ethnic group. The most important culture of this period is that of the city of Tartessos. Beginning in the 9th century BC, Celtic tribes entered the Iberian peninsula through the Pyrenees and settled throughout the peninsula, becoming the Celt-Iberians.
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.
Roman Catholicism is, by far, the most popular religion in the country, with four in five Spaniards (80%) self-identifying as Catholics. The next group (one in eight, or 12%) is represented by atheists or agnostics. Minority religions account for one in seventy (1.4%) of all Spaniards.
Modern Spain began to take form during the Reconquista, the struggle between the Christian kingdoms arising in the northern regions left unconquered by the Moors and the Muslim kingdoms into which Al-Andalus eventually split.
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).
In 1898 Spain lost the Spanish-American War. Cuba gained its independence, and Spain lost its remaining New World colonies—Guam, the Philippines, and Puerto Rico—to the United States. Spain's colonial possessions were reduced to Spanish Morocco, Western Sahara and Equatorial Guinea.
As recently as the mid-20th-century, much of Spain (especially outside of the major cities) remained quite distinct from the rest of Europe. In 1954, V.S. Pritchett could still write of small Spanish towns, "The inn, if there is one, will not be a hotel, nor even a fonda — the Arab word — but perhaps a posada: a place one can ride into with a mule or a donkey, where one can stable an animal and lie down oneself on a sack of straw, the other side of the stall." [Pritchett, 1954 p. 46-47] However, especially since the 1975 death of Francisco Franco, Spain has become increasingly European; Pritchett's rustic posada would be unimaginable today.
In order to understand the political forces and debates in Spain we have to consider two dimensions: the Right vs. Left dimension and the Nation State vs. Plurinational State dimension. The political parties agendas and the individual citizens opinions can only understood when situated on both dimensions. The Constitution of the Kingdom of Spain states that 1) it is a Nation and 2) that it is formed by Nationalities and Regions. This statement is a contradiction (since Nationality and Nation essentially mean the same thing in political theory), but it was an agreement that struck a balance between the political parties advocating the nation state and those advocating the plurinational state. The territorial organization of Spain into Autonomous Communities of Spain is the administrative realization of this constitutional balancing act.
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.
