The period of Visigothic rule saw the spread of Arianism briefly in Spain. In 587, Reccared, the Visigothic king at Toledo, having been converted to Catholicism put an end to dissension on the question of Arianism and launched a movement in Spain to unify the various religious doctrines that existed in the land. The Council of Lerida in 546 constrained the clergy and extended the power of law over them under the blessings of Rome.
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.
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.
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.
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 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.
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.
