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.
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.
The latter years of Franco's rule saw some economic and political liberalization, the so-called Spanish Miracle, including the birth of a tourism industry. Francisco Franco ruled until his death on November 20th 1975 when control was given to King Juan Carlos. In the last few months before Franco's death, the Spanish state went into a paralysis. This was capitalized upon by King Hassan of Morocco, who ordered the 'Green March' into Western Sahara, Spain's last colonial possession.
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.
Through a policy of alliances with other European nobility and the conquest of most of South America and the West Indies, Spain began to establish itself as an empire. The Treaty of Tordesillas, negotiated by Pope Alexander VI between Portugal and Spain, effectively divided up the non-European world between these two budding empires. Massive amounts of gold and silver were imported from the New World into Spain's coffers. However, in the long run this hurt the Spanish economy much more than it helped it. The bullion caused high inflation rates, which undermined the value of Spain's currency. Additionally, Spain became dependent on her colonies for income, and when Queen Elizabeth I of England began to capture Spanish vessels on the way to and from the New World, Spain suffered massive economic losses. These effects, combined with the expulsion of Spain's most economically vital classes in the late 15th century (the Jews and the Moors), caused Spain's economy to collapse several times in the 16th century, bringing the Golden Age of Spain to a close.
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.
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.
Contemporary Madrid came into its own after the death of the Fascist dictator Franco. Years of the Franco regime left Madrid and much the country in economic shambles due to isolation. With his death, Madrid and Spain as a whole began to re-assert itself on the international stage. Within Spain, reaction against the dictatorial bureaucracy centered in Madrid and a history of centralism that pre-dated Franco by centuries has resulted in the successful modern movement towards increased autonomy for the regions of Spain, considered as European regions, under the umbrella of Spain.
Spain suffered a shocking terrorist attack, the March 11, 2004 Madrid attacks on its capital's commuter train network, killing 200. Al-Qaeda has been blamed for this attack. Some have attributed the fall of the Aznar government to this attack, which took place just two days before the 2004 elections. At first the public believed ETA was responsible for the bombing. When they learned Al-Qaeda was the true culprit, many voters lashed out at the media and Aznar's government, believing the two had colluded to deceive the public.
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.
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.
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).
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.
