The
Pre-Roman Iron Age of Northern Europe (5th/4th–1st century BC) was the earliest part of the
Iron Age in Scandinavia, northern
Germany, and the
Netherlands north of the
Rhine River. These regions feature many extensive archaeological excavation sites, which have yielded a wealth of artifacts. Objects discovered at the sites suggest that the Pre-Roman Iron Age cultures evolved without a major break out of the
Nordic Bronze Age, but that there were strong influences from the
Celtic Iron-Age
Hallstatt culture in Central Europe. During the 1st century BC, Roman influence began to be felt even in Denmark.
