The Arecomici were probably first recognized or defined as a political entity by Rome around 75 BC. According to anthropologist Michael Dietler, the Roman colonization of the region, which led to the organization of Nemausus as a
colonia Latina in the late 1st century AD, "resulted in the
ethnogenesis of the Volcae Arecomici out of a formerly fluid coalition of different polities and ethnic groups". They were indeed part of a political confederation encompassing multiple smaller tribes. By the early first century AD, the Volcae Arecomici were the dominant force of the confederation, ruling over twenty-four subject towns (
oppida ignobilia) from their capital Nemausus. == Economy ==
