The Cimbrian War (113–101 BC) was fought between the Roman Republic and the Germanic tribes of the Cimbri and the Teutones, who migrated from the Jutland peninsula 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. The timing of the war had a great effect on the internal politics of Rome, and the organization of its military.
