Germania, also more specifically called Magna Germania, Germania Libera, or Germanic Barbaricum to distinguish it from the Roman provinces of Germania Inferior and Germania Superior, was a historical region in north-central Europe during the Roman era, which was associated by Roman authors with the Germanic peoples. According to Roman geographers, this region stretched roughly from the Rhine in the west to the Vistula in the east, and to the Upper Danube in the south, and the known parts of southern Scandinavia in the north. Archaeologically, these people correspond roughly to the Roman Iron Age of those regions.
