The Roman conquest of much of the west Mediterranean led to major transformations and this study discusses some aspects of the economic and political impact of such changes. Based largely on archaeological material Perez examines, for example, the Greek-Italian wine trade, major production centres in the Mediterranean, how goods from centres such as Etruria, Lazio and Campania ended up in cities recently conquered by Rome, in particular the markets and commercial routes along which products moved.
