Describes how assumptions about the nature of war have shaped our understanding of the modern world and the role of war within it.

Two broad competing normative conceptions of war can be distinguished in the history of legal and political thought. The first and nowadays more familiar belongs to the tradition of "just war." It sees war as an instrument of justice, indeed the most extreme form of supra-national lawenforcement, justified only in the most serious cases of violation of right. The second conception has been labelled "lawful", "legitimate", or "regular war", where war is not enforcement of justice, but a legally regulated procedure governing the pursuit of conflicting legitimate claims amongequal and autonomous political entities.This book sheds light on the relationship between law and morals in armed conflict, and can be read as a historical argument against the disappearance of the regular war concept. Kalmanovitz highlights three important contemporary challenges: the juridification of aggression and the "turn to ethics"in international law; the progressive individualization of war; and the predominance of asymmetrical warfare and armed nonstate actors.This study of the regular war tradition brings historical and theoretical perspective to these recent conceptual transformations, which undermine the fundamental and long-standing distinction between war and police action. It contributes to clarify the stakes in the erosion of internationalpluralism and the normative depoliticization of war. In revisiting the regular war tradition, a clearer sense of these ongoing transformations is realised, inspiring fresh perspectives on the justifiability of war.

Who has the right to wage war? The answer to this question constitutes one of the most fundamental organizing principles of any international order. Under contemporary international humanitarian law, this right is essentially restricted to sovereign states. It has been conventionally assumed that this arrangement derives from the ideas of the late-sixteenth century jurist Alberico Gentili. Claire Vergerio argues that this story is a myth, invented in the late 1800s by a group of prominent international lawyers who crafted what would become the contemporary laws of war. These lawyers reinterpreted Gentili's writings on war after centuries of marginal interest, and this revival was deeply intertwined with a project of making the modern sovereign state the sole subject of international law. By uncovering the genesis and diffusion of this narrative, Vergerio calls for a profound reassessment of when and with what consequences war became the exclusive prerogative of sovereign states.

This unique collection presents texts in international relations from Ancient Greece to the First World War. Major writers such as Thucydides, Augustine, Aquinas, Machiavelli, Grotius, Kant and John Stuart Mill are represented by extracts of their key works; less well-known international theorists including John of Paris, Cornelius van Bynkershoek and Friedrich List are also included. Fifty writers are anthologised in what is the largest such collection currently available. The texts, most of which are substantial extracts, are organised into broadly chronological sections, each of which is headed by an introduction that places the work in its historical and philosophical context. Ideal for both students and scholars, the volume also includes biographies and guides to further reading.
