The Cimbri were an ancient people, either Germanic or Celtic who, together with the Teutones and the Ambrones, fought the Roman Republic between 113 and 101 BC. The Cimbri were initially successful, particularly at the Battle of Arausio, in which a large Roman army was routed, after which they raided large areas in Gaul and Hispania. In 101 BC, during an attempted invasion of Italy, the Cimbri were decisively defeated by Gaius Marius, and their king, Boiorix, was killed. Some of the surviving captives are reported to have been among the rebelling Gladiators in the Third Servile War.
Roman sources such as Strabo and Tacitus identify these Cimbri with a group living in Jutland, but strong evidence for this connection is lacking.
Archaeologists have not found any clear indications of a mass migration from Jutland in the early Iron Age. The Gundestrup Cauldron, which was deposited in a bog in Himmerland in the 2nd or 1st century BC, shows that there was some sort of contact with southeastern Europe, but it is uncertain if this contact can be associated with the Cimbrian expedition.
Advocates for a northern homeland point to Greek and Roman sources that associate the Cimbri with the peninsula of Jutland, Denmark. According to the Res gestae (ch. 26) of Augustus, the Cimbri were still found in the area around the turn of the 1st century AD:
