The Routledge Handbook of Ideology and International Relations reviews, consolidates, and advances the study of ideology in international politics. The volume unifies fragmented scholarship on ideology's impact on international relations into a wide-ranging and go-to volume. Declarations of the 'end of ideology' have once again been proven premature: nationalisms of various stripes are thriving; ideological polarization and conflicts both within and among states are growing; and environmentalist, feminist and anti-globalization activists are intensifying their demands on international institutions and states. This timely volume presents ideology as a way of explaining these major developments of world politics, rejecting the simplistic association of ideology with passionate convictions in favor of more complex theories of ideology's influence. The chapters summarize cutting edge knowledge on major topics, suggest key implications for broader theoretical debates and frameworks, and point the way forwards to future avenues of inquiry. Contributors adopt puzzle-orientated causal, constitutive and/or critical approaches with a central focus on the determinants and effects of ideological phenomena and their interaction with other aspects of politics. This handbook is of key interest to students and scholars of ideologies, international relations, foreign policy analysis, political science, political theory and more broadly to sociology, psychology, and history. The Routledge Handbook of Ideology and International Relations is part of the mini-series Routledge Handbooks on Political Ideologies, Practices and Interpretations, edited by Michael Freeden.

In research on 'mass killings' such as genocides and campaigns of state terror, the role of ideology is hotly debated. For some scholars, ideologies are crucial in providing the extremist goals and hatreds that motivate ideologically committed people to kill. But many other scholars are sceptical: contending that perpetrators of mass killing rarely seem ideologically committed, and that rational self-interest or powerful forms of social pressure are more important drivers of violence than ideology. In Ideology and Mass Killing, Jonathan Leader Maynard challenges both these prevailing views, advancing an alternative 'neo-ideological' perspective which systematically retheorises the key ideological foundations of large-scale violence against civilians. Integrating cutting-edge research from multiple disciplines, including political science, political psychology, history and sociology, Ideology and Mass Killing demonstrates that ideological justifications vitally shape such violence in ways that go beyond deep ideological commitment. Most disturbingly of all, the key ideological foundations of mass killings are found to lie, not in extraordinary political goals or hatreds, but in radicalised versions of those conventional, widely accepted ideas that underpin the politics of security in ordinary societies across the world. This study then substantiates this account by a detailed examination of four contrasting cases of mass killing - Stalinist Repression in the Soviet Union between 1930 and 1938, the Allied Bombing Campaign against Germany and Japan in World War II from 1940 to 1945, mass atrocities in the Guatemalan Civil War between 1978 and 1983, and the Rwandan Genocide in 1994. This represents the first volume to offer a dedicated, comparative theory of ideology's role in mass killing, while also developing a powerful new account of how ideology affects violence and politics more generally.
