The book opens with a description of the peoples of Italy at around the end of the fourth century BC. It describes the early success of Roman diplomacy and force in creating client populations among the Etruscans, the Latins and the Hellenized populations of the south. At the beginning of the period the Italian peoples sought to preserve their independence and ethnic traditions. By its end those who had not achieved Roman citizenship were demanding it.
The author describes the dramatic change in the Roman economy and polity during the period. He also examines the causes and consequences of the massive changes in population that took place, including the effects of the enslavement and importation of large numbers of defeated rebels (including, for example, over one million Gauls). This is an outstanding history of the formative years of Roman power. It is concisely and clearly written and takes full account of recent scholarship and archaeological discoveries in Italy.
