Archaeology of Northern Europe in the context of "Nordic Bronze Age"

In Europe, the Iron Age is the last stage of the prehistoric period and the first of the protohistoric periods, which initially meant descriptions of a particular area by Greek and Roman writers. For much of Europe, the period came to an abrupt end after conquest by the Romans, though ironworking remained the dominant technology until recent times. Elsewhere, the period lasted until the early centuries AD, and either Christianization or a new conquest in the Migration Period.Iron working was introduced to Europe in the late 11th century BC, probably from the Caucasus, and slowly spread northwards and westwards over the succeeding 500 years. For example, the Iron Age of Prehistoric Ireland begins around 500 BC, when the Greek Iron Age had already ended, and finishes around 400 AD. The use of iron and iron-working technology became widespread concurrently in Europe and Asia.

The start of the Iron Age is marked by new cultural groupings, or at least terms for them, with the Late Bronze Age Mycenaean Greece collapsing in some confusion, while in Central Europe the Urnfield culture had already given way to the Hallstatt culture. In north Italy the Villanovan culture is regarded as the start of Etruscan civilization. Like its successor La Tène culture, Hallstatt is regarded as Celtic. Further to the east and north, and in Iberia and the Balkans, there are a number of local terms for the early Iron Age culture. Roman Iron Age is a term used in the archaeology of Northern Europe (but not Britain) for the period when the unconquered peoples of the area lived under the influence of the Roman Empire.
