The insurrectionists of Gaul and Spain who were known as the Bacaudae/Bagaudae constitute one of the more intriguing yet obscure anti-Roman resistance movements of the later Roman Empire. Establishing the correct spelling and meaning of their name may help in identifying them. Many scholars have concluded that ‘Bagaudae' is the correct form because of its association with the Celtic root bág (fight) and the fact that the Bacaudae were ‘warriors' or ‘fighters' whom the Romans regarded as ‘rebels'. Here it will be argued that the form ‘Bacaudae' precedes the form ‘Bagaudae' and that all hypotheses about the Bacaudae based on G-form of their name must be revised.
