Archaeology of Northern Europe

Expansion of early Germanic tribes into previously mostly Celtic Central Europe:[2]

   Settlements before 750 BC

   New settlements by 500 BC

   New settlements by 250 BC

   New settlements by AD 1

Some sources also give a date of 750 BC for the earliest expansion out of southern Scandinavia and northern Germany along the North Sea coast towards the mouth of the Rhine.[3]

The Pre-Roman Iron Age (5th/4th–1st centuries BC) was the earliest part of the Iron Age in Scandinavia and the North European Plain. Succeeding the Nordic Bronze Age, the Iron Age developed in contact with the Hallstatt culture in Central Europe.[4]

Archaeologists first decided to divide the Iron Age of Northern Europe into distinct pre-Roman and Roman Iron Ages after Emil Vedel unearthed a number of Iron Age artifacts in 1866 on the island of Bornholm.[5] They did not exhibit the same permeating Roman influence seen in most other artifacts from the early centuries AD, indicating that parts of northern Europe had not yet come into contact with the Romans at the beginning of the Iron Age.

Out of the Late Bronze Age Urnfield culture of the 12th century BC developed the Early Iron Age Hallstatt culture of Central Europe from the 8th to 6th centuries BC, which was followed by the La Tène culture of Central Europe (450 BC to 1st century BC). Although the metal iron came into wider use by metalsmiths in the Mediterranean as far back as c. 1300 BC due to the Late Bronze Age collapse, the Pre-Roman Iron Age of Northern Europe covered the 5th/4th to the 1st centuries BC.

The Iron Age in northern Europe is markedly distinct from the Celtic La Tène culture south of it. The old long-range trading networks south–north between the Mediterranean cultures and Northern Europe had broken down at the end of the Nordic Bronze Age and caused a rapid and deep cultural change in Scandinavia. Bronze, which was an imported alloy, suddenly became very scarce; and iron, which was a local natural resource, slowly became more abundant, as the techniques for extracting, smelting and smithing it were acquired from their Central European Celtic neighbours. Iron was extracted from bog iron in peat bogs, and the first iron objects to be fabricated were needles and edged tools such as swords and sickles. The rise of iron use in Scandinavia was slow: bog ore was only abundant in southwestern Jutland and it was not until 200–100 BC that iron-working techniques were generally mastered and a productive smithing industry had evolved in the larger settlements. Iron products were also known in Scandinavia during the Bronze Age, but they were a scarce imported material. Similarly, imported bronze continued to be used during the Iron Age in Scandinavia, but it was now much scarcer and mostly used for decoration.[6]

Funerary practices continued the Bronze Age tradition of burning corpses and placing the remains in urns, a characteristic of the Urnfield culture. During the previous centuries, influences from the Central European La Tène culture had spread to Scandinavia from north-western Germany, and there are finds from this period from all the provinces of southern Scandinavia. Archaeologists have found swords, shield bosses, spearheads, scissors, sickles, pincers, knives, needles, buckles, kettles, etc. from this time. Bronze continued to be used for torcs and kettles, the styles of which were continuous from the Bronze Age. Some of the most prominent finds from the pre-Roman Iron Age in northern Europe are the Gundestrup cauldron and the Dejbjerg wagons, two four-wheeled wagons of wood with bronze parts.

The cultural change that ended the Nordic Bronze Age was influenced by the expansion of Hallstatt culture from the south and accompanied by a changing climate, which caused a dramatic change in the flora and fauna. In Scandinavia, this period is often called the "Findless Age", due to the lack of archaeological finds. While the archaeological record from Scandinavia is consistent with an initial decline in population, the southern part of the culture, the Jastorf culture, was in expansion southwards. It consequently appears that climate change played an important role in this southward expansion into continental Europe. It is debated why cultural innovation spread geographically during this time: whether the new material culture reflects a possibly warlike movement of Germanic peoples ("demic diffusion") southwards or whether innovations found at the Pre-Roman Iron Age sites represent a more peaceful trans-cultural diffusion. The current view in the Netherlands is that Iron Age innovations, starting with Hallstatt (800 BC), did not involve intrusions and featured a local development from Bronze Age culture.[7] Another Iron Age nucleus considered to represent a local development is the Wessenstedt culture (800–600 BC).

The bearers of this northern Iron Age culture were likely speakers of Germanic languages. The stage of development of this Germanic is not known, although Proto-Germanic has been proposed. The late phase of this period sees the beginnings of the Migration Period, starting with the invasions of the Teutons and the Cimbri until their defeat at the Battle of Aquae Sextiae in 102 BC, presaging the more turbulent Roman Iron Age and Migration Period.

The Roman Iron Age (1–400 AD) is a part of the Iron Age. The name comes from the hold that the Roman Empire had begun to exert on the Germanic tribes of Northern Europe.

In Scandinavia, there was a great import of goods, such as coins, vessels, bronze images, glass beakers, enameled buckles, weapons, etc. Moreover, the style of metal objects and clay vessels was markedly Roman. Objects such as shears and pawns appear for the first time. In the 3rd and 4th centuries, some elements are imported from Germanic tribes that had settled north of the Black Sea, such as the runes.

There are also many bog bodies from this time in Denmark, Schleswig and southern Sweden. Together with the bodies, there are weapons, household wares and clothes of wool. The prime burial tradition was cremation, but the third century and thereafter saw an increase in inhumation. Great ships made for rowing have been found from the 4th century in Nydam Mose in southern Denmark.

The Gudme Hall complex, a ruling elite residence and cult site, was built in Denmark in the 3rd century.[10] In Norway the large chiefly hall at Borg (Lofotr) was built around 500 AD. At Upkåkra in Sweden, the largest Iron Age settlement in Scandinavia developed from c. 200 AD onwards.[11][12] A wooden temple was built at Upkåkra in the 3rd century and continued to be used and rebuilt over 600 years, into the early Viking Age.[13]

Through the 5th and 6th centuries, gold and silver become more and more common. This time saw the ransack of the Roman Empire by Germanic tribes, from which many Scandinavians returned with gold and silver. A new Iron Age had begun in Northern Europe, the Germanic Iron Age.

The Germanic Iron Age is divided into the Early Germanic Iron Age (EGIA) and the late Germanic Iron Age (LGIA). In Sweden, the LGIA (550–800) is usually called the Vendel era; in Norway and Finland, the Merovinger (Merovingian) Age.

The Germanic Iron Age begins with the fall of the Roman Empire and the rise of the Germanic kingdoms in Western Europe.[19] It is followed, in Northern Europe and Scandinavia, by the Viking Age.

During the decline of the Roman Empire, an abundance of gold flowed into Scandinavia; there are excellent works in gold from this period. Gold was used to make scabbard mountings and bracteates.

After the Western Roman Empire fell, gold became scarce and Scandinavians began to make objects of gilded bronze, with decorative figures of interlacing animals. During the EGIA, decorations tended to be representational; the animal figures were drawn in more basic forms. In the LGIA, artistic styles became more abstract, symbolic, and intricate, including figures with interlaced shapes and limbs.

The LGIA in the 8th century blends into the Viking Age and the proto-historical period, with legendary or semi-legendary oral tradition recorded a few centuries later in the Gesta Danorum, heroic legend and sagas, and an incipient tradition of primary written documents in the form of runestones.
