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.
The expulsion of the Muslims was reputedly started by the first King of Asturias, named Pelayo (718-737), who started his fight against the Moors in the mountains of Covadonga (722). Later, his sons and descendants continued with his work until all of the Muslims were expelled. Meanwhile, in the east of the peninsula the Frankish emperors established the Marca Hispanica across the Pyrenees in part of what today is Catalonia, reconquering Girona in 785 and Barcelona in 801. It was a buffer zone against Islam.
Philip V, the first Bourbon king, of French origin, signed the Decreto de Nueva Planta in 1715, a new law that revoked most of the historical rights and privileges of the different kingdoms that conformed the Spanish Crown, unifying them under the laws of Castile, where the Cortes had been more receptive to the royal wish. Spain became culturally and politically a follower of France. The rule of the Spanish Bourbons continued under Ferdinand VI and Charles III. His son Carlos IV was truly incompetent (some say mentally handicapped), and under his reign Spain fell to the armies of Napoleon.
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.
Madrid is also noted for its nightlife and discotheques. Younger madrileños sometimes dance all night, stop off for chocolate y churros at dawn, go home, shower, shave, and go to work. This nightlife, called la movida or la marcha and initially focussed on the Plaza del Dos de Mayo, flourished after the death of Franco, especially during the 80's while Madrid's most cherished mayor Enrique Tierno Galván was in office. A particular hub for this night activity is nowadays the nearby gay village of Chueca. However, as prices continue to rise and more jobs become available, nightlife in Madrid is becoming more and more like that of other European cities such as Stockholm or Munich.
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.
According to the latest official poll, 80% of Spaniards self-identify as Catholic, 12% as non-believer, and 1% as other (the remaining 7% declined to state). Of the 1.4% identifying as other, 29% identified as Evangelical Christian, 26% as Jehovah's Witnesses and 3% as Muslim (the rest either mentioned smaller religions or declined to state). According to the same poll, 73% believe in God, 14% don't and 12% are unsure (1% declined to state). Additionally, according to this poll, only 41% believe in Heaven. 24% of the Spaniards think that the Bible is just a fable. Only 25% of Catholics go to church at least once a week.
Spain was part of the Roman Empire and many areas of Spain retain significant Roman architectural remnants. The Roman aqueduct at Segovia is still in use as of 2004; Mérida, now the Extermaduran capital but once the capital of the Roman province of Lusitania, retains over 5 miles of its Roman aqueduct, Roman bridge over the River Guadiana, an arch of Trajan, and significant remnants of a Roman forum, amphitheatre, and a temple popularly accounted to have been dedicated to Diana (goddess). Another Roman bridge crosses the Tagus River at Alcántara. Lesser Roman ruins can be found in the heart of Barcelona.
In 711, Arabs and Berbers had converted to Islam, a religion founded in the 7th century by prophet Muhammad and which by the 8th dominated all the north of Africa. A raiding party led by Tariq ibn-Ziyad was sent to intervene in a civil war in the Visigothic kingdoms in Iberia. Crossing the Strait of Gibraltar, it won a decisive victory in the summer of 711 when the Visigoth king Roderic was defeated and killed on July 19th at the Battle of Guadalete. Tariq's commander, Musa bin Nusair quickly crossed with substantial reinforcements, and by 718 the Muslims dominated most of the peninsula. The advance into Europe was stopped by the Franks under Charles Martel at the battle of Poitiers (France) in 732.
Spain is considered by many, including a large part of Spanish population, to be a group of nations unified under a single State, much like Belgium, Switzerland or the United Kingdom. Despite this, the policy of many Spanish governments has led to a "Spanish nationhood" which is the one people identify with Spain internationally.
The dictatorship of Miguel Primo de Rivera collapsed in 1930. Disgusted with the king's involvement in it, urban population voted for republican parties in the municipal elections of April 1931. The king was forced to resign and a republic was established.
