Prehistoric Iberia

The Chalcolithic or Copper Age is the earliest phase of metallurgy. Copper, silver and gold started to be worked then, though these soft metals could hardly replace stone tools for most purposes. The Chalcolithic is also a period of increased social complexity and stratification and, in the case of Iberia, that of the rise of the first civilizations and of extensive exchange networks that would reach to the Baltic and Africa. The conventional date for the beginning of Chalcolithic in Iberia is c. 3200 BC. In the following centuries, especially in the south of the peninsula, metal goods, often decorative or ritual, become increasingly common. Additionally there is an increased evidence of exchanges with areas far away: amber from the Baltic and ivory and ostrich-egg products from Northern Africa.^[8] A notable example in that regard is the Ivory Lady from Tholos de Montelirio.


The Bell Beaker culture was present in Iberia during the Chalcolithic.^[18] Gordon Childe interpreted the presence of its characteristic artefact as the intrusion of "missionaries" expanding from Iberia along the Atlantic coast, spreading knowledge of Mediterranean copper metallurgy. Stephen Shennan interpreted their artefacts as belonging to a mobile cultural elite imposing itself over the indigenous substrate populations. Similarly, Sangmeister (1972) interpreted the "Beaker folk" (Glockenbecherleute) as small groups of highly mobile traders and artisans. Christian Strahm (1995) used the term "Bell Beaker phenomenon" (Glockenbecher-Phänomen) as a compromise in order to avoid the term "culture".


The Bell Beaker artefacts at least in their early phase are not distributed across a contiguous areal as is usual for archaeological cultures, but are found in insular concentrations scattered across Europe. Their presence is not associated with a characteristic type of architecture or of burial customs. However, the Bell Beaker culture does appear to coalesce into a coherent archaeological culture in its later phase.


More recent analyses of the "Beaker phenomenon", published since the 2000s, have persisted in describing the origin of the "Beaker phenomenon" as arising from a synthesis of elements, representing "an idea and style uniting different regions with different cultural traditions and background.


"Archaeogenetics studies of the 2010s have been able to resolve the "migrationist vs. diffusionist" question to some extent. The study by Olalde et al. (2017) found only "limited genetic affinity" between individuals associated with the Beaker complex in Iberia and in Central Europe, suggesting that migration played a limited role in its early spread from Iberia. However, the same study found that the further dissemination of the mature Beaker complex was very strongly linked to migration. The spread and fluidity of the Beaker culture back and forth between the Rhine and its origin source in the peninsula may have introduced high levels of steppe-related ancestry, resulting in a near-complete transformation of the local gene pool within a few centuries, to the point of replacement of about 90% of the local Mesolithic-Neolithic patrilineal lineages.


The origin of the "Bell Beaker" artefact itself has been traced to the early 3rd millennium. The earliest examples of the "maritime" Bell Beaker design have been found at the Tagus estuary in Portugal, radiocarbon dated to c. the 28th century BC. The inspiration for the Maritime Bell Beaker is argued to have been the small and earlier Copoz beakers that have impressed decoration and which are found widely around the Tagus estuary in Portugal. Turek has recorded late Neolithic precursors in northern Africa, arguing the Maritime style emerged as a result of seaborne contacts between Iberia and Morocco in the first half of the third millennium BCE. In only a few centuries of their maritime spread, by 2600 BC. they had reached the rich lower Rhine estuary and further upstream into Bohemia and beyond the Elbe where they merged with Corded Ware culture, as also in the French coast of Provence and upstream the Rhone into the Alps and Danube.


A significant Chalcolithic archeological site in Portugal is the Castro of Vila Nova de São Pedro. Other settlements from this period include Pedra do Ouro and the Castro of Zambujal.^[18] Megaliths were created during this period, having started earlier, during the late 5th, and lasting until the early 2nd millennium BC.^[18] The Castelo Velho de Freixo de Numão, in Vila Nova de Foz Côa Municipality, was populated from about 3000 to 1300 BC.^[19] The Cerro do Castelo de Santa Justa, in Alcoutim, is dated to the 3rd millennium BC,^[20] between 2400 and 1900 BC.^[18]


It is also the period of the great expansion of megalithism, with its associated collective burial practices. In the early Chalcolithic period this cultural phenomenon, maybe of religious undertones, expands along the Atlantic regions and also through the south of the peninsula (additionally it's also found in virtually all European Atlantic regions). In contrast, most of the interior and the Mediterranean regions remain refractary to this phenomenon.


Another phenomenon found in the early chalcolithic is the development of new types of funerary monuments: tholoi and artificial caves. These are only found in the more developed areas: southern Iberia, from the Tagus estuary to Almería, and SE France.


Eventually, c. 2600 BC, urban communities began to appear, again especially in the south. The most important ones are Los Millares in SE Spain and Zambujal (belonging to Vila Nova de São Pedro culture) in Portuguese Estremadura, that can well be called civilizations, even if they lack of the literary component.


It is very unclear if any cultural influence originated in the Eastern Mediterranean (Cyprus?) could have sparked these civilizations. On one side the tholos does have a precedent in that area (even if not used yet as tomb) but on the other there is no material evidence of any exchange between the Eastern and Western Mediterranean, in contrast with the abundance of goods imported from Northern Europe and Africa.^[8]


Since c. 2150 BC, the Bell Beaker culture intrudes in Chalcolithic Iberia. After the early Corded style beaker, of quite clear Central European origin, the peninsula begins producing its own types of Bell Beaker pottery. Most important is the Maritime or International style that, associated especially with Megalithism, is for some centuries abundant in all the peninsula and southern France.


Since c. 1900 BC, the Bell Beaker phenomenon in Iberia shows a regionalization, with different styles being produced in the various regions: Palmela type in Portugal, Continental type in the plateau and Almerian type in Los Millares, among others.^[8]


Like in other parts of Europe, the Bell Beaker phenomenon (speculated to be of trading or maybe religious nature) does not significantly alter the cultures it inserts itself in. Instead the cultural contexts that existed previously continue basically unchanged by its presence.
