The Cimbrian War (113-101 BC) was fought between the Roman Republic and the Proto-Germanic tribes of the Cimbri and the Proto-Germanic Teutons (Teutones), who migrated from northern Europe into Roman controlled territory, and clashed with Rome and her allies. The Cimbrian War was the first time since the Second Punic War that Italia and Rome itself had been seriously threatened.
