"A strength of Eckstein’s volume is the balance of international relations theory with the detailed history of the transformation of the Hellenistic multipolar anarchy from the First Illyrian War to the period of Roman “unipolarity”. This consolidates the placement of political theory within current historiography of the interstate relations of the mid- Republic and Hellenistic world. Based on the reception of IR Realism in the various studies cited here which have engaged directly or peripherally with Eckstein’s volume, there are two major ideas for which he argues that are already working their way through the ancient historical consciousness: that fear, threat, force and violence underpin interstate discourses and were commonplace in the experiences and strategies of both primary and secondary polities; and that all polities were stakeholders in international relations, with neither Roman (or others’) ambivalence preventing their participation, nor secondary states’ comparative weakness limiting their determination to join the negotiation of conflict. We shall in future see much more scholarship based upon these two central arguments."   (Bryn Mawr Classical Review, 7 May 2013)
