After the fall of the Roman Empire, Germanic tribes invaded the former empire, several turned sedentary and created successor-kingdoms to the Romans in various parts of Europe. Iberia was taken over by the Visigoths after 410.In the Iberian peninsula, as elsewhere, the Empire fell not with a bang but with a whimper. Rather than there being any convenient date for the "fall of the Roman Empire" there was a progressive "de-Romanization" of the Western Roman Empire in Hispania and a weakening of central authority, throughout the 3rd, 4th and 5th centuries. At the same time, there was a process of "Romanization" of the Germanic and Hunnic tribes settled on both sides of the limes (the fortified frontier of the Empire along the Rhine and Danube rivers). The Visigoths, for example, were converted to Arian Christianity around 360, even before they were pushed into imperial territory by the expansion of the Huns. In the winter of 406, taking advantage of the frozen Rhine, the (Germanic) Vandals and Sueves, and the (Asiatic) Alans invaded the empire in force. Three years later they crossed the Pyrenees into Iberia and divided the Western parts, roughly corresponding to modern Portugal and western Spain as far as Madrid, between them. The Visigoths meanwhile, having sacked Rome two years earlier, arrived in the region in 412 founding the Visigothic kingdom of Toulouse (in the south of modern France) and gradually expanded their influence into the Iberian peninsula at the expense of the Vandals and Alans, who moved on into North Africa without leaving much permanent mark on Hispanic culture. The Visigothic kingdom shifted its capital to Toledo and reached a high point during the reign of Leovigild, treated in some detail at its own entry.
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.
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 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.
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.
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.
Terrorism is a problem of present-day Spain, since ETA (Basque Homeland and Freedom) is trying to achieve Basque independence through violent means, including bombings and murders. Although Basque Autonomous government does not condone any kind of violence, the different approaches to the problem are a source of tension between Central and Basque governments. Besides ETA violence, the conflict in the Basque Country is also shaped by the non-acceptance on the part of the spanish state of the right of basque people to choose freely their political status. Recently, 2 political parties - which in previous elections had received the support of around 15% of the popular vote- have been banned due to their negative to condemn publicly ETA violence in the terms that the main spanish political parties wanted.
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.
The Romans arrived in the Iberian peninsula during the Second Punic war in the 2nd century B.C., and annexed it under Augustus after two centuries of war with the Celtic and Iberian tribes and the Phoenician, Greek and Carthaginian colonies becoming the province of Hispania. Some of Spain's present languages, religion, and laws originate from this Roman period.
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.
