During the final four centuries BC, many political and stateless entities of the Mediterranean headed towards anarchy and militarism, while stronger powers -Carthage, the Hellenistic kingdoms and Republican Rome- expanded towards State formation, forceful military structures and empire building.

Edited by T. Ñaco del Hoyo and F. López Sánchez, this volume presents the proceedings from an ICREA Conference held in Barcelona (2013), addressing the connection between war, warlords and interstate relations from classical studies and social sciences perspectives.

Some twenty scholars from European, Japanese and North American Universities consider the scope of ‘multipolarity’ and the usefulness of ‘warlord’, a modern category, in order to feature some ancient military and political leaderships.
