The disappearance and formation of states and nations after the end of the Cold War have proved puzzling to both theorists and policymakers. Lars-Erik Cederman argues that this lack of conceptual preparation stems from two tendencies in conventional theorizing. First, the dominant focus on cohesive nation-states as the only actors of world politics obscures crucial differences between the state and the nation. Second, traditional theory usually treats these units as fixed. Cederman offers a fresh way of analyzing world politics: complex adaptive systems modeling. He provides a new series of models--not ones that rely on rational-choice, but rather computerized thought-experiments--that separate the state from the nation and incorporate these as emergent rather than preconceived actors. This theory of the emergent actor shifts attention away from the exclusively behavioral focus of conventional international relations theory toward a truly dynamic perspective that treats the actors of world politics as dependent rather than independent variables. Cederman illustrates that while structural realist predictions about unit-level invariance hold up under certain circumstances, they are heavily dependent on fierce power competition, which can result in unipolarity instead of the balance of power. He provides a thorough examination of the processes of nationalist mobilization and coordination in multi-ethnic states. Cederman states that such states' efforts to instill loyalty in their ethnically diverse populations may backfire, and that, moreover, if the revolutionary movement is culturally split, its identity becomes more inclusive as the power gap in the imperial center's favor increases.

Critical and scientific realism have emerged as important perspectives on international relations in recent years. The attraction of these approaches lies in the claim that they can transcend the positivism vs postpositivism divide. This book demonstrates the vitality of this approach and the difference that 'realism' makes.

This book shows how changing diplomatic practices are central in explaining key dimensions of world politics, from law to war.

Non-State Actors in Conflicts: Conspiracies, Myths, and Practices explores some of the most pressing topics in political science and media studies. The contributions gathered here provide alternative perspectives on various non-state actors and their functions in global politics, in addition to providing case studies and theoretical approaches towards non-state actors, such as armed non-state actors and international non-governmental organizations. The volume also covers the topic of conspiracy theories and conspiracies formed in relation to the functions and existence of these actors.

An examination of the ways cyberspace is changing both the theory and the practice of international relations.

The »return of great power competition« between (among others) the US, China, Russia and the EU is a major topic in contemporary public debate. But why do we think of world politics in terms of »competition«? Which information and which rules enable states and other actors in world politics to »compete« with one another? Which competitive strategies do they pursue in the complex environment of modern world politics? This cutting-edge edited collection discusses these questions from a unique interdisciplinary perspective. It offers a fresh account of competition in world politics, looking beyond its military dimensions to questions of economics, technology and prestige.

A world government capable of controlling nation-states has never evolved, but governance does underlie order among states and gives direction to problems arising from global interdependence. This book examines the ideological bases and behavioural patterns of this governance without government.
