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 period of Visigothic rule saw the spread of Arianism briefly in Spain. In 587, Reccared, the Visigothic king at Toledo, having been converted to Catholicism put an end to dissension on the question of Arianism and launched a movement in Spain to unify the various religious doctrines that existed in the land. The Council of Lerida in 546 constrained the clergy and extended the power of law over them under the blessings of Rome.
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.
Around 1,100 BC Phoenician merchants founded the trading colony of Gadir or Gades (modern day Cádiz) near Tartessos. In the 8th century BC the first Greek colonies, such as Emporion (modern Empúries), were founded along the Mediterranean coast on the East, leaving the south coast to the Phoenicians. The Greeks are responsible for the name Iberia, after the river Iber (Ebro in Spanish). In the 6th century BC the Carthaginians arrived in Iberia while struggling with the Greeks for control of the Western Mediterranean. Their most important colony was Carthago Nova (Latin name of modern day Cartagena).
After World War II, being one of few surviving fascist regimes in Europe, Spain was politically and economically isolated and was kept out of the United Nations until 1955, when it became strategically important for U.S. president Eisenhower to establish a military presence in the Iberian peninsula. This opening to Spain was aided by Franco's rabid anti-communism.
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.
The dry weather of Spain resulted in the importance of water fountains in Spanish urban design. In addition, ceramics figure prominently in architecture throughout Spain, especially in the tile roofs and the use of decorative tiles known as azulejos.
The most important minority group in the country are the Gitanos. Other indigenous minorities are Mercheros (or Quinquis) and Vaqueiros de alzada.- The latter, meaning "Mountain cow-breeders" dwell in mountain ranges in the Principality of Asturias and have kept historically apart from the valley dwellers. Foreign minorities include South Americans from countries like Argentina, Ecuador or Colombia; black Africans; Arabs and Berbers mainly from Morocco and other countries of North Africa; and Asians from China, Japan, Korea, and Vietnam.
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.
Historically, various regions of Spain had quite distinct regional dress. Today, most people in Spain dress in a manner comparable to most other contemporary Europeans, although some regional variations persist. Dress in Extremadura and in the smaller cities of Castile remains relatively austere, even on festive occasions, while Andaluz dress on festive occasions is elaborate and ostentatious. Barcelona is one of the most stylish cities in Europe, though more restrained and with a more determinedly timeless style than Paris or Milan.
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.
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.
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.
