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.
While the siesta — an hours-long mid-afternoon break from work — is generally in decline, the typical rhythm of the day in Spain remains relatively distinct from the European norm. Many shops and some museums (though relatively few other businesses) still split their hours into two distinct periods of opening with a two or three hour break in the middle; a paseo (stroll) in the early evening remains a common custom in many smaller cities and to some extent even in the larger ones; the dinner hour is the latest in Europe, typically about 10 p.m.; nightlife begins accordingly late, with many dance clubs (even in relatively small cities) opening at midnight and staying open until dawn; in Madrid in the summer there is nothing unusual about a live musical performance being scheduled for one or two o'clock in the morning.
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.
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.
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.
Philip V, the first Bourbon king, of French origin, signed the Decreto de Nueva Planta in 1715, a new law that revoked most of the historical rights and privileges of the different kingdoms that conformed the Spanish Crown, unifying them under the laws of Castile, where the Cortes had been more receptive to the royal wish. Spain became culturally and politically a follower of France. The rule of the Spanish Bourbons continued under Ferdinand VI and Charles III. His son Carlos IV was truly incompetent (some say mentally handicapped), and under his reign Spain fell to the armies of Napoleon.
Through a policy of alliances with other European nobility and the conquest of most of South America and the West Indies, Spain began to establish itself as an empire. The Treaty of Tordesillas, negotiated by Pope Alexander VI between Portugal and Spain, effectively divided up the non-European world between these two budding empires. Massive amounts of gold and silver were imported from the New World into Spain's coffers. However, in the long run this hurt the Spanish economy much more than it helped it. The bullion caused high inflation rates, which undermined the value of Spain's currency. Additionally, Spain became dependent on her colonies for income, and when Queen Elizabeth I of England began to capture Spanish vessels on the way to and from the New World, Spain suffered massive economic losses. These effects, combined with the expulsion of Spain's most economically vital classes in the late 15th century (the Jews and the Moors), caused Spain's economy to collapse several times in the 16th century, bringing the Golden Age of Spain to a close.
