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.
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.
Spain never entered the period of the Dark Ages such as were endured in Britain, Gaul, Lombardy and Germany. The Visigoths tended to maintain more of the old Roman institutions, and they had a unique respect for legal codes that resulted in continuous frameworks and historical records for most of the period between 415, when Visigothic rule in Spain began, and 711, when it is traditionally said to end. The proximity of the Visigothic kingdoms to the Mediterranean and the continuity of western Mediterranean trade, though in reduced quantity, supported Visigothic culture. Arian Visigothic nobility kept apart from the local Catholic population. The Visigoth ruling class looked to Constantinople for style and technology while the rivals of Visigothic power and culture were the Catholic bishops— and a brief incursion of Byzantine power in Cordoba.
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.
Madrid, the capital of Spain, is located in the center of the country. Population of the city of Madrid proper was 3,093,000 as of 2003 estimates.
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.
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.
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 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.
Spanish rule in Morocco ended in 1956. Though militarily victorious in the 1957-1958 Moroccan invasion of Spanish West Africa, Spain gradually relinquished its remaining African colonies. Spanish Guinea was granted independence as Equatorial Guinea in 1968, while the Moroccan enclave of Ifni had been ceded to Morocco in 1969.
A revived movement for the Christian unification of Spain was capitalized on by the "Catholic monarchs" (Reyes Católicos in Spanish) Isabel I of Castilla and Fernando II of Aragón in order to justify their invasion of Granada, the expulsion of the Jews and the forceful conversion of the Moors. In the 15th century, the Kingdoms of Castile and Aragon were united under Isabel and Fernando. These two able rulers ruled jointly and worked to consolidate the power of the monarchy at the expense of the nobility. During their reign, the castles of many nobles (symbols of aristocratic independence from the monarchy) were demolished, and a system of regular taxation was established. Fernando and Isabel established the basis for the unification of Spain religiously as well as politically and economically.
