The Bagaudae Revolt (409-417) was a violent conflict in the early 5th century, involving part of the population in northwestern Gaul. The uprising was an indirect result of the Rhine crossing in 405–406, through which various Germanic peoples invaded the Western Roman Empire, as well as the revolt of the army in Britannia and the resulting civil war. In the following period, the Gallic population largely had to rely on itself and formed self-defense groups, which were called Bagaudae. In mid-409, groups of Bagaudae in the Loire Valley and Brittany rebelled against the Roman regime. The course of this uprising has been briefly reported. Most of the information comes from the work of the Byzantine historian Zosimus (460-515), the Roman poet Rutilus Namatianus and the priest Salvianus from Marseille.
