Migratory Germanic (Cimbri, from Jutland) and allied (Teutones) peoples who left their homeland en masse and rampaged through Gaul, Iberia, and northern Italy, inflicting several catastrophic defeats on Roman armies (notably Arausio, 105 BCE) before being annihilated by Gaius Marius.
Destroyed as an organized military threat by Marius at the Battle of Aquae Sextiae (Teutones, 102 BCE) and the Battle of Vercellae (Cimbri, 101 BCE); survivors were enslaved or dispersed, ending the migration.
