The increase in archaeological knowledge sheds new light on the presence of the Roman army and conflict archaeology in the Caput Adriae region and on the eastern coast of the Adriatic Sea. The nine contributions by 19 authors from four countries (Italy, Slovenia, Croatia and Austria) summarise the historical, epigraphic and archaeological evidence. The main part of the book is devoted to the northern Adriatic and its hinterland in the 2nd and 1st centuries BC. The topography of the first year of the Histrian War (178-177 BC) is examined in the context of a historical debate. The archaeological evidence of the early Roman military presence is discussed in the chapters on the military camps of San Rocco and Grociana piccola, the beginnings of Tergeste on the hill of San Giusto, the conflicts with the autochthonous population, and the epigraphic evidence of the Roman army. The remains of the early Roman camps provide a new insight into the landscape of central Dalmatia. On the basis of written sources, the Roman offensive policy in the southern Adriatic, in the Ionian region and in the interior of the Balkans is analysed.
