Book excerpt: How should we understand the ways in which the regions of Italy were affected by Roman imperialism? This book, which is the first full-scale treatment of ancient Umbria in any language, takes a balanced view of the region's history in the first millennium BC, focusing on local actions and motivations as much as the effect of outside influences and Roman policies. Through a careful reading of all the types of evidence it provides an important challenge to traditional treatments emphasising the 'Romanization' of the region, arguing that this is a poor explanation for the complexity of local societies in the late Republican period. Instead it proposes that other trends, particularly the organization of states, help to explain the fascinating plurality of identities that are evident in the imperial period and allow us to appreciate the diversity of local societies that emerged in both mountain and lowland areas of Umbria.
