This introductory textbook on international relations theory brings together a selection of leading experts to offer an unparalleled insight into the main paradigms and latest developments in the discipline. Presenting a full range of theories, from realism and liberalism to institutionalism and green theory, the sixth edition of this book has been extensively revised to offer a more global introduction to international relations. It showcases insights from across the world, and employs a historical and sociological perspective throughout to demonstrate how any understanding of IR is time and place contingent. New to this edition are two new chapters on postcolonialism and institutionalism, as well as boxed cases which apply theory to contemporary empirical examples including gendered policy in the UN, the phenomenon of 'fake news', issues on migration, and the crisis of the Amazon's forest fires. Assuming no prior knowledge of international relations theory, this text remains the definitive companion for all students of international relations and anyone with an interest in the latest scholarship of this fascinating field.

International relations affects everyone's lives: their security, economic well-being, rights and freedoms, and the environment they share. Recently we have seen the transformation from a world of empires to today's world of sovereign states, which are enmeshed in a complex array of international institutions, all exercising degrees of political authority. The new global organization of political authority has far-reaching consequences. This Very Short Introduction untangles this complex world, providing an accessible framework for understanding the contours of global political change. Christian Reus-Smit treats theory as an indispensable tool for grasping international relations, but demystifies theorizing, introducing it as an everyday human practice. He surveys a range of theories, from realism to feminism: reading them as contrasting perspectives on the global organization of political authority. Historically, such organization has been shaped by diverse social forces, four of which are discussed in detail: shifting patterns of warfare, changing economic conditions, struggles for rights, and the politics of culture. Reus-Smit concludes with a reflection on the future of international relations in an era of profound global change. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

This book seeks to explain why different systems of sovereign states have built different types of fundamental institutions to govern interstate relations. Why, for example, did the ancient Greeks operate a successful system of third-party arbitration, while international society today rests on a combination of international law and multilateral diplomacy? Why did the city-states of Renaissance Italy develop a system of oratorical diplomacy, while the states of absolutist Europe relied on naturalist international law and "old diplomacy"? Conventional explanations of basic institutional practices have difficulty accounting for such variation. Christian Reus-Smit addresses this problem by presenting an alternative, "constructivist" theory of international institutional development, one that emphasizes the relationship between the social identity of the state and the nature and origin of basic institutional practices.

Reus-Smit argues that international societies are shaped by deep constitutional structures that are based on prevailing beliefs about the moral purpose of the state, the organizing principle of sovereignty, and the norm of procedural justice. These structures inform the imaginations of institutional architects as they develop and adjust institutional arrangements between states. As he shows with detailed reference to ancient Greece, Renaissance Italy, absolutist Europe, and the modern world, different cultural and historical contexts lead to profoundly different constitutional structures and institutional practices. The first major study of its kind, this book is a significant addition to our theoretical and empirical understanding of international relations, past and present.

The Globalization of International Society re-examines the development of today's society of sovereign states, drawing on a wealth of new scholarship to challenge the landmark account presented in Bull and Watson's classic work, The Expansion of International Society (OUP, 1984). For Bull and Watson, international society originated in Europe, and expanded as successive waves of new states were integrated into a rule-governed order. International society, on their view, was thus a European cultural artefact - a claim that is at odds with recent scholarship in history, politics, and related fields of research. Bringing together leading scholars from Asia, Australia, Europe, and the United States, this book provides an alternative account: it draws out the diversity of polities that existed at around c1500; it shows how interacting identities, political orders, and economic forces were intensifying within and across regions; it details the tangled dynamics that helped to globalize the European conception of a pluralist international society, through patterns of warfare and between East and West. The Globalization of International Society examines the institutional contours of contemporary international society, with its unique blend of universal sovereignty and global law, and its forms of hierarchy that coexist with commitments to international human rights. The book explores the multiple forms of contestation that challenge international society today: contests over the limits of sovereignty in relation to cosmopolitan conceptions of responsibility, disputes over global governance, concerns about persistent economic, racial, and gender-based patterns of disadvantage, and lastly the threat to the established order opened up by the disruptive power of digital communications.

The Oxford Handbook of International Relations offers the most authoritative and comprehensive overview to date of the field of international relations. Arguably the most impressive collection of international relations scholars ever brought together within one volume, the Handbook debates the nature of the field itself, critically engages with the major theories, surveys a wide spectrum of methods, addresses the relationship between scholarship and policy making, and examines the field's relation with cognate disciplines. The Handbook takes as its central themes the interaction between empirical and normative inquiry that permeates all theorizing in the field and the way in which contending approaches have shaped one another. In doing so, the Handbook provides an authoritative and critical introduction to the subject and establishes a sense of the field as a dynamic realm of argument and inquiry. The Oxford Handbook of International Relations will be essential reading for all of those interested in the advanced study of global politics and international affairs.

The rise of non-Western Great Powers, the spread of transnational religiously-justified insurgencies, and the resurgence of ethno-nationalism raise fundamental questions about the effects of cultural diversity on international order. Yet current debate - among academics, popular commentators, and policy-makers alike - rests on flawed understandings of culture and inaccurate assumptions about how historically cultural diversity has shaped the evolution of international orders. In this path-breaking book, Christian Reus-Smit details how the major theories of international relations have consistently misunderstood the nature and effects of culture, returning time and again to a conception long abandoned in specialist fields: the idea of cultures as coherent, bounded, and constitutive. Drawing on theoretical insights from anthropology, cultural studies, and sociology, and informed by new histories of diverse historical orders, this book presents a new theoretical account of the relationship between cultural diversity and international order: an account with far-reaching implications for how we understand contemporary transformations.

Understanding how cultural diversity relates to international order is an urgent contemporary challenge. Building on ideas first advanced in Reus-Smit's On Cultural Diversity (2018), this groundbreaking book advances a new framework for understanding the nexus between culture and order in world politics. Through a pioneering interdisciplinary collaboration between leading historians, international lawyers, sociologists and international relations scholars, it argues that cultural diversity in social life is ubiquitous rather than exceptional, and demonstrates that the organization of cultural diversity has been inextricably tied to the constitution and legitimation of political authority in diverse international orders, from Warring States China, through early modern Europe and the Ottoman and Qing Empires, to today's global liberal order. It highlights the successive 'diversity regimes' that have been constructed to govern cultural difference since the nineteenth century, traces the exclusions and resistances these projects have engendered and considers contemporary global vulnerabilities and axes of contestation.

We live today in the first global system of sovereign states in history, encompassing all of the world's polities, peoples, religions and civilizations. Christian Reus-Smit presents a new account of how this system came to be, one in which struggles for individual rights play a central role. The international system expanded from its original European core in five great waves, each involving the fragmentation of one or more empires into a host of successor sovereign states. In the most important, associated with the Westphalian settlement, the independence of Latin America, and post-1945 decolonization, the mobilization of new ideas about individual rights challenged imperial legitimacy, and when empires failed to recognize these new rights, subject peoples sought sovereign independence. Combining theoretical innovation with detailed historical case studies, this book advances a new understanding of human rights and world politics, with individual rights deeply implicated in the making of the global sovereign order.

The language of special responsibilities is ubiquitous in world politics, with policymakers and commentators alike speaking and acting as though particular states have, or ought to have, unique obligations in managing global problems. Surprisingly, scholars are yet to provide any in-depth analysis of this fascinating aspect of world politics. This path-breaking study examines the nature of special responsibilities, the complex politics that surround them and how they condition international social power. The argument is illustrated with detailed case-studies of nuclear proliferation, climate change and global finance. All three problems have been addressed by an allocation of special responsibilities, but while this has structured politics in these areas, it has also been the subject of ongoing contestation. With a focus on the United States, this book argues that power must be understood as a social phenomenon and that American power varies significantly across security, economic and environmental domains.

Politics and law appear deeply entwined in contemporary international relations. Yet existing perspectives struggle to understand the complex interplay between these aspects of international life. In this path-breaking volume, a group of leading international relations scholars and legal theorists advance a new constructivist perspective on the politics of international law. They reconceive politics as a field of human action that stands at the intersection of issues of identity, purpose, ethics, and strategy, and define law as an historically contingent institutional expression of such politics. They explain how liberal politics has conditioned modern international law and how law 'feeds back' to constitute international relations and world politics. This new perspective on the politics of international law is illustrated through detailed case-studies of the use of force, climate change, landmines, migrant rights, the International Criminal Court, the Kosovo bombing campaign, international financial institutions, and global governance.
