Iberian Peninsula

• 1. Introduction

  ›

  The Iberian Peninsula covers roughly 583,254 square kilometers, and it holds about 53 million people. That makes it the second-largest peninsula in Europe, behind only the Scandinavian Peninsula. The Pyrenees mountains seal it off from the rest of the continent so completely that there is no easy way across except by mountain road, trail, coastal road, or tunnel. Inside this rough octagon sit Peninsular Spain and Continental Portugal, which together fill almost the whole region. Andorra, Gibraltar, and a small slice of France complete the map. The ancient geographer Strabo looked at its shape and compared it to an ox-hide. How did one stretch of land at Europe's far western edge gather so many names, so many peoples, and so many languages? Who walked here first, more than a million years before any country drew a border? And why did the kingdoms of this place spend centuries fighting over a single river crossing at Gibraltar?

• 2. A River And Its Names

  The River Ebro gave the peninsula its oldest identity. In ancient Greek it was Ibēros, and in Latin Ibērus or Hibērus, and the link was so familiar that writers rarely bothered to explain it. Strabo described Iberia as the country on this side of the Ibērus. Pliny went further, claiming the Greeks named the whole peninsula Hiberia after the river. Polybius noted that the native form was Ibēr, the original word before Greek or Latin endings were attached.

  The Ebro fixed a hard political line in 226 BCE. The Ebro Treaty between Rome and Carthage set the limit of Carthaginian interest at the river, and Appian's fuller account of the deal uses the name Ibērus. The people called Iberians once ranged, by the reckoning of geographers and historians, from present southern Spain up to present southern France along the Mediterranean coast. They left behind a readable script that records a language still not understood. Because that language remains unknown, the meaning of the word Iber stays unknown too.

  The modern phrase Iberian Peninsula is surprisingly young. The French geographer Jean-Baptiste Bory de Saint-Vincent coined it in his 1823 work Guide du Voyageur en Espagne. Before that, geographers reached for Spanish Peninsula or Pyrenaean Peninsula instead.

• 3. Confusion Of Empires

  The Greeks first heard of this land from the Phoenicians, then sailed west across the Mediterranean to reach it. Hecataeus of Miletus was the first known writer to use the term Iberia, around 500 BCE. Herodotus credited the Phocaeans with making the Greeks acquainted with Iberia. The name carried a built-in trap. The very same word, Iberia, named the Kingdom of Iberia in the Caucasus, known natively as Kartli, the core of what became Georgia.

  The Romans added their own layer of names. According to Charles Ebel, Latin and Greek sources used Hispania and Hiberia as synonyms, the words overlapping in political and geographic sense. The first mention in Roman literature came from the annalist poet Ennius in 200 BCE. Virgil later wrote of the restless Iberi in his Georgics. As Rome grew interested in former Carthaginian land, it split the territory into Hispania Citerior and Hispania Ulterior, near and far Hispania.

  Other names clung to the place across cultures. In Greek and Roman antiquity Hesperia could mean either the Italian or the Iberian Peninsula, so Roman writers used Hesperia Ultima for the far west to tell them apart. Since Roman antiquity, Jews have called the peninsula Sepharad.

• 4. Deep Prehistory

  ›

  Members of the Homo genus have lived on the peninsula for at least 1.2 million years, shown by remains in the Atapuerca Mountains. In the cave of Gran Dolina, six hominin skeletons were found in 1994, dated between 780,000 and one million years ago. Experts have argued over whether they belong to Homo erectus, Homo heidelbergensis, or a new species, Homo antecessor.

  Neanderthals first entered around 200,000 years before present, during the Lower Paleolithic. Their Châtelperronian culture, beginning around 37,000 years before present, spread out of Southern France into the north of the peninsula. It lasted until roughly 30,000 years before present, when Neanderthal man faced extinction. Anatomically modern humans had crossed the Pyrenees about 40,000 years ago, and they developed cultures such as the Aurignacian, Gravettian, Solutrean, and Magdalenian, some marked by the complex art of the Upper Paleolithic.

  The Bronze Age brought a striking genetic shift. The dominance of Y-Chromosome Haplogroup R1b reflects waves of mostly male Western Steppe Herders from the Pontic-Caspian steppe. Iberia saw 100 percent of its paternal ancestry replaced, and 40 percent of its overall ancestry, by people carrying steppe-related ancestry.

  The Chalcolithic, around 3000 BCE, produced cultures linked by exchange networks that reached the Baltic, the Middle East, and North Africa. The Beaker culture, maker of the Maritime Bell Beaker, probably arose around 2800 to 2700 BCE in the copper-using communities of the Tagus estuary, then spread to many parts of western Europe. The Bronze Age proper began in 2100 calibrated BC according to radiocarbon dating of key sites.

  The Argaric culture ruled southeastern Iberia from 2200 BC to 1550 BC. The most accepted model treats El Argar as an early state society defined by class division, exploitation, and coercion, with larger hilltop settlements controlling agricultural production and using violence to hold down the population. Ecological degradation, fires, pastoralism, and tree cutting for mining have been suggested as reasons for its collapse, followed by depopulation and the loss of copper-bronze-arsenic metallurgy.

  The motillas tell a story of water and drought. These early groundwater supply plants developed in the upper Guadiana basin during extreme aridification linked to the 4.2-kiloyear climatic event. When rainfall returned and the water table recovered from about 1800 BC, the motillas may have flooded, prompting their abandonment and a new relationship with the land.

• 6. Traders And Conquerors

  ›

  As early as the 12th century BCE, the Phoenicians began exploring the coastline, drawn to the metal-rich communities of the southwest known as the semi-mythical Tartessos. Around 1100 BCE they founded the trading colony of Gadir, modern Cádiz, then made it a permanent port around 800 BCE to meet the Assyrian Empire's hunger for silver. Greek colonists arrived in the 8th century BCE, founding Emporion, modern Empúries, while leaving the south coast to the Phoenicians. In the sixth century BCE the Carthaginians came, contesting the Western Mediterranean with the Greeks, and built their chief colony at Carthago Nova, modern Cartagena.

  Roman troops first landed in 218 BCE, during the Second Punic War. A 195 campaign under Cato the Elder ravaged resistance in the northeastern Ebro Valley, yet the Celtiberian Wars and the Lusitanian War dragged on through the 2nd century. Roman mining in the southwest drove atmospheric pollution across the Mediterranean to levels unmatched until the Industrial Revolution. The region also produced sigillata pottery, colourless glass, linen, fish sauce known as garum, esparto, olive oil, and wine.

  The Romans stayed for six centuries. During that occupation they introduced Latin, which grew into the peninsula's modern languages, with one exception. The language of the Vascones survived as a language isolate, protected by the barrier of the Pyrenees.

• 7. Al-Andalus And The Christian Kingdoms

  ›

  In 711, a Muslim army under Tariq ibn Ziyad landed at Gibraltar and, in an eight-year campaign, conquered all but the northern kingdoms. Muslim Iberia took the Arabic name Al-Andalus, possibly meaning Land of the Vandals. The conquerors were Arabs and Berbers, and supremacy of Arabs over the rest was a recurring cause of strife. Christians and Jews lived in a stratified society under the dhimmah system. After the Abbasids shifted the Caliphate's center to Baghdad, the marginalised western province became an independent emirate in 756 under Abd al-Rahman I.

  The Caliphate of Córdoba turned the region into a center of culture and learning. Under Abd-ar-Rahman III and his successor al-Hakam II it became, in the view of Jaime Vicens Vives, the most powerful state in Europe. Córdoba reached a population of 100,000 by the 10th century, Toledo 30,000 by the 11th, and Seville 80,000 by the 12th. After the Fitna of al-Andalus, the Caliphate collapsed in the early 11th century into small statelets called taifas.

  The Christian kingdoms pushed south in a process later called the Reconquista, a term scholars note oversimplifies centuries of warring and peaceable contact between 711 and 1492. Alfonso VI of León-Castile took Toledo in 1085, a critical event that prompted the Almoravids to land in 1086 and crush him at the battle of Zalaca. The Almohads, a Masmuda Berber sect, first entered in 1146. The last stronghold, Granada, fell to a combined Castilian and Aragonese force in 1492.

  Tarifa marks the southernmost point of the European continent, sitting close to Africa across the Strait of Gibraltar. The peninsula stretches about 865 kilometers from Punta de Tarifa north to Punta de Estaca de Bares, and about 1,155 kilometers from Cabo da Roca west to Cap de Creus. Mountain ranges run mostly west to east, some reaching about 3,000 meters, giving the region the second highest mean altitude in Western Europe at 637 meters. The highest point of all is Mulhacén in the Sierra Nevada, at 3,478 meters. About three quarters of the land is the Meseta Central, a plateau ringed by mountains that holds the sources of most rivers, including the Ebro, Douro, Tagus, Guadiana, and Guadalquivir.

  The peninsula is also a vital crossroads for life. It is a key stopover on the East Atlantic flyway for birds flying from northern Europe to Africa, and some seven million wading birds from the north winter in its estuaries and wetlands. The endangered Iberian lynx serves as a symbol of the Iberian mediterranean forest and of the region's fauna. A new lizard, Podarcis virescens, native to the peninsula and found near rivers, was accepted as a species in 2020.

  Modern movement reshaped the human map too. The strong urban development after World War II ran alongside heavy rural flight, far outpacing the tamer changes of the 19th-century liberal revolutions. By 1490 the Iberian kingdoms held an estimated 6.525 million people, with the Crown of Castile alone counting 4.3 million.
