After the conquest of Gaul in 58 BC, the policy of Rome was not to create, but to organise and rationalise the structures that already existed in Gaul, and Augustus the Emporer finalised these arrangements. Gaul was divided into Provinces, but the territories of the different tribes were left, “by and large,” untouched. Tacitus puts the number of Gallic civitates at sixty-four, while Strabo states that there were sixty.
