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).
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.
In 1499, about 50,000 Moors in Granada were coerced by Cardinal Cisneros into mass baptisms and conversion. During the uprising that followed (known as the First Rebellion of the Alpujarras), people who refused the choices of baptism or deportation to Africa, were systematically eliminated. What followed was a mass flee of Moors, Jews and Gitanos from Granada city and the villages to the mountain regions (and their hills) and the rural country, however by 1500 Cisneros reported that "There is now no one in the city who is not a Christian, and all the mosques are churches".
Spain is considered by many, including a large part of Spanish population, to be a group of nations unified under a single State, much like Belgium, Switzerland or the United Kingdom. Despite this, the policy of many Spanish governments has led to a "Spanish nationhood" which is the one people identify with Spain internationally.
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.
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.
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.
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.
The Complutense University is one of the oldest universities in the world, as well as the largest and (after Salamanca) most prestigious in Spain. It has 10000 staff and a student population of 117 000. It is located on two campuses, in the university quarter Ciudad Universitaria at Moncloa in Madrid, and in Somosaguas.
