Spain is a constitutional monarchy, with a hereditary monarch and a bicameral parliament, the Cortes Generales or National Assembly. The executive branch consists of a Council of Ministers presided over by the President of Government (comparable to a prime minister), proposed by the monarch and elected by the National Assembly following legislative elections.
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.
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.
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.
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.
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.
Except for the subtropical Canary Islands, Spain can be divided into areas experiencing, respectively, a Mediterranean climate; a climate dominated by the Atlantic Ocean; and (in the inner areas) a rather extreme climate with hotter summers and colder winters than nearer the coasts. The generally warm and relatively dry summers have led to a culture in which a lot of life is lived outdoors, whether on a patio in the courtyard of a building or on a public plaza. In Madrid, many of the most popular nightclubs move for several months in the summer to an outdoor terrasa much farther from the center of town than their indoor winter location, continuing in a way the older tradition of the verbena (fair). In the Mediterranean areas (and in the Canary Islands), outdoor meals can be a nearly year-round phenomenon.
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.
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).
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).
