With the approval of the Spanish Constitution of 1978 and the arrival of democracy, the old historic nationalities — Basque Country, Catalonia, Galicia and Andalusia— were given far-reaching autonomy, which was then soon extended to all Spanish regions, resulting in one of the most decentralized territorial organizations in Western Europe.
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.
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.
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.
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.
The first governments of the Republic, were center-left, headed by Niceto Alcalá-Zamora, and Manuel Azaña. In 1933, the right-wing CEDA won power; an armed rising of workers of October 1934, which reached its greatest intensity in Asturias and Catalonia, was forcefully put down by the CEDA government.
Madrid, the capital of Spain, is located in the center of the country. Population of the city of Madrid proper was 3,093,000 as of 2003 estimates.
Over the past thirty years, Spain has become a more secularised society. The number of believers has decreased significantly and for those who believe the degree of accordance and practice to their church is quite diverse.
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.
The most important minority group in the country are the Gitanos. Other indigenous minorities are Mercheros (or Quinquis) and Vaqueiros de alzada.- The latter, meaning "Mountain cow-breeders" dwell in mountain ranges in the Principality of Asturias and have kept historically apart from the valley dwellers. Foreign minorities include South Americans from countries like Argentina, Ecuador or Colombia; black Africans; Arabs and Berbers mainly from Morocco and other countries of North Africa; and Asians from China, Japan, Korea, and Vietnam.
The original peoples of the Iberian peninsula (in the sense that they are not known to have come from elsewhere), consisting of a number of separate tribes, are given the generic name of Iberians. This may have included the Basques, the only pre-Celtic people in Iberia surviving to the present day as a separate ethnic group. The most important culture of this period is that of the city of Tartessos. Beginning in the 9th century BC, Celtic tribes entered the Iberian peninsula through the Pyrenees and settled throughout the peninsula, becoming the Celt-Iberians.
