Comprising a plurality of perspectives, this timely Handbook is an essential resource for understanding past and current challenges to democracy, justice, social and gender equality, identity and freedom. It shows how critical international relations (IR) theory functions as a broad-based and diverse critique of society. The chapters explore key new areas of research, including critical emotion and critical animal studies, drawing from Marxist, poststructuralist, feminist, realist and post-colonial backgrounds. Structured in four thematic parts, the Handbook of Critical International Relations moves from discussing approaches and emancipation, through concepts and configuration, and political economy and domination, to global trajectories and challenges. Emphasising non-Western IR viewpoints, it offers cutting-edge insights into the notion of otherness, the dialectics of authoritarian neoliberalism, and agonistic recognition. Graduate and undergraduate international relations scholars will benefit from the solid, working understanding of critical IR offered in the detailed chapters on the varied approaches, concepts and new areas of research in the field. Critical IR research institutions and policy-makers will also appreciate the discussion of, and advice offered on, key issues and challenges facing democracy and justice.
