In 109 BC Provence faced a new invasion from the north. An enormous migration of Celto-Germanic tribes, the Teutons and Cimbri, left the Baltic coast and moved south into Gaul, looking for a new homeland. They moved into the Rhône Valley and in 105 BC defeated the Roman legions of Gnaeus Mallius Maximus and Servilus Caepio at Arausio (the modern town of Orange).
