The Romans divided these huge provinces into "civitates" corresponding more or less with the pre-Conquest communities or polities sometimes described misleadingly as "tribes," such as the Aedui, Allobroges, Bellovaci, and Sequani (see List of Celtic tribes) but the civitates were too large and in turn were divided into smaller units, "pagi", a term that eventually became the modern French word "pays". These administrative groupings would be taken over by the Romans in their system of local control, and these "civitates" would also be the basis of France's eventual division into ecclesiastical bishoprics and dioceses, which would remain in place—with slight changes—until the French revolution.
