Book excerpt: When the Roman Republic became the master of an overseas empire, the Romans had to adapt their civic institutions so as to be able to rule the dominions that were successively subjected to their imperium. As a result, Rome created an administrative structure mainly based on an element that became the keystone of its empire: the provincia. This book brings together nine contributions from a total of ten scholars, all specialists in Republican Rome and the Principate, who analyse from diverse perspectives and approaches the distinct ways in which the Roman res publica constituted and ruled a far-flung empire. The book ranges from the development of the Roman institutional structures to the diplomatic and administrative activities carried out by the Roman commanders overseas. Beyond the subject on which each author focuses, all chapters in this volume represent significant and renewed contributions to the study of the provinces and the Roman empire during the Republican period and the transition to the Principate.
