Cassels offers a novel perspective on the part played by ideology in international relations over the past two centuries. His treatment is not restricted to the familiar totalitarian ideologies of communism and nazism, but also includes conservatism, liberalism and nationalism. The focus and emphasis given to ideology in an historical survey of such broad scope make this book unusual, and even controversial.

Are theoretical tools nothing but political weapons? How can the two be distinguished from each other? What is the ideological role of theories like liberalism, neoliberalism or democratic theory? And how can we study the theories of actors from outside the academic world? This book examines these and related questions at the nexus of theory and ideology in International Relations. The current crisis of politics made it abundantly clear that theory is not merely an impartial and neutral academic tool, but instead is implicated in political struggles. However, it is also clear that it is insufficient to view theory merely as a political weapon. This book brings together contributions from a number of different scholarly perspectives to engage with these problems. The contributors, drawn from various fields of International Relations and Political Science, cast new light on the ever-problematic relationship between theory and ideology. They analyse the ideological underpinnings of existing academic theories and examine the theories of non-academic actors such as staff members of international organisations, Ecovillagers and liberal politicians. This edited volume is a must-read for all those interested in the contemporary political crisis and its relation to theories of International Relations.

Winner, 2023 Joseph Fletcher Prize for Best Edited Book in Historical International Relations, History Section, International Studies Association Ideology drives American foreign policy in ways seen and unseen. Racialized notions of subjecthood and civilization underlay the political revolution of eighteenth-century white colonizers; neoconservatism, neoliberalism, and unilateralism propelled the post–Cold War United States to unleash catastrophe in the Middle East. Ideologies order and explain the world, project the illusion of controllable outcomes, and often explain success and failure. How does the history of U.S. foreign relations appear differently when viewed through the lens of ideology? This book explores the ideological landscape of international relations from the colonial era to the present. Contributors examine ideologies developed to justify—or resist—white settler colonialism and free-trade imperialism, and they discuss the role of nationalism in immigration policy. The book reveals new insights on the role of ideas at the intersection of U.S. foreign and domestic policy and politics. It shows how the ideals coded as “civilization,” “freedom,” and “democracy” legitimized U.S. military interventions and enabled foreign leaders to turn American power to their benefit. The book traces the ideological struggle over competing visions of democracy and of American democracy’s place in the world and in history. It highlights sources beyond the realm of traditional diplomatic history, including nonstate actors and historically marginalized voices. Featuring the foremost specialists as well as rising stars, this book offers a foundational statement on the intellectual history of U.S. foreign policy.

A new theoretical framework for understanding how social, economic, and political conflicts influence international institutions and their place in the global order Today’s liberal international institutional order is being challenged by the rising power of illiberal states and by domestic political changes inside liberal states. Against this backdrop, Ideology and International Institutions offers a broader understanding of international institutions by arguing that the politics of multilateralism has always been based on ideology and ideological divisions. Erik Voeten develops new theories and measures to make sense of past and current challenges to multilateral institutions. Voeten presents a straightforward theoretical framework that analyzes multilateral institutions as attempts by states to shift the policies of others toward their preferred ideological positions. He then measures how states have positioned themselves in global ideological conflicts during the past seventy-five years. Empirical chapters illustrate how ideological struggles shape the design of international institutions, membership in international institutions, and the critical role of multilateral institutions in militarized conflicts. Voeten also examines populism’s rise and other ideological threats to the liberal international order. Ideology and International Institutions explores the essential ways in which ideological contestation has influenced world politics.

Political ideologies shape the behaviour of states, international institutions, terrorist groups, political elites, non-governmental organisations, and other international actors. The book analyses how the most important of them affect today’s world politics, and contribute to build a new and complex world order.

Contemporary discourse about human affairs is largely grounded in the specific historical experience and interests of a few dominant societies. This poses an important challenge to all those who urge that we need to adopt a global perspective on modern political life, whether in terms of international relations, comparative and developmental politi
