At present, Spain is a constitutional monarchy, and is comprised of 17 autonomous communities. One of the most important problems facing Spain today is ETA's terrorism - this illegal organization defends Basque independence through violent means, which is condemned by both Central and Basque government, although there is tension between these governments since PNV (the party presently governing Basque Country) longs for greater autonomy from Spain, including the possibility of independence, something Spanish government doesn't accept.
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.
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.
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.
As the Roman empire declined, the Suebi, Vandals and Alans each took control of part of Hispania. In the 5th century AD the Visigoths, a romanized germanic tribe, conquered all of Hispania and established a relatively stable kingdom lasting until 711, when it fell to an invasion by Islamic North African Moors and became part of the expanding Umayyad empire, under the name of Al-Andalus. When the Umayyad empire gave way to the Abbaside empire, an Umayyad exile established the Caliphate of Cordoba, effectively making Al-Andalus independent from the empire.
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.
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.
In the 1960s, more than a decade later than other western European countries, Spain began to enjoy economic growth and gradually transformed into a modern industrial economy with a thriving tourism sector. Growth continued well into the 1970s, with Franco's government going to great lengths to shield the Spanish people from the effects of the oil crisis.
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.
In 1499, about 50,000 Moors in Granada were coerced by Cardinal Cisneros into mass baptisms and conversion. During the uprising that followed (known as the First Rebellion of the Alpujarras), people who refused the choices of baptism or deportation to Africa, were systematically eliminated. What followed was a mass flee of Moors, Jews and Gitanos from Granada city and the villages to the mountain regions (and their hills) and the rural country, however by 1500 Cisneros reported that "There is now no one in the city who is not a Christian, and all the mosques are churches".
Under the Bonaparte, Spain failed to embrace the mercantile and industrial revolutions of the 18th century, and also failed to absorb the ideals that of the Enlightenment that were revolutionizing European thought. These missed opportunities, combined with the economic failures of the 17th century, caused the country to fall desperately behind Britain, France, and Germany in economic and political power.
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.
