Germania (/dʒərˈmeɪni.ə/ jər-MAY-nee-ə; Latin: [ɡɛrˈmaːni.a]), also more specifically called Magna Germania (English: Greater Germania), Germania Libera (English: Free Germania), 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.
The Latin name Germania means "land of the Germani", but the etymology of the name Germani itself is uncertain. During the Gallic Wars of the 1st century BC, the Roman general Julius Caesar encountered Germani originating from beyond the Rhine. He referred to their lands beyond the Rhine as "Germania". West of the Rhine, the prosperous Roman provinces of Germania Superior and Germania Inferior, sometimes collectively referred to as "Roman Germania", were established in northeast Roman Gaul, while territories east of the Rhine remained independent of Roman control. The Roman emperors also sought to expand east of the Rhine to the Elbe, but these efforts were hampered by the victory of Arminius at the Battle of the Teutoburg Forest in 9 AD.
