War, Peace and Justice

The research group War, Peace and Justice brings together scholars, researchers as well as current and former practitioners to explore issues related to the drivers, nature and (new) dynamics of war and conflict, comprehensive approaches to the promotion of sustainable peace, and the role of justice and human rights in the context of conflict, peace and global affairs.

Matthew Hoye

Whilst each of the three themes of war, peace and justice has a long and rich intellectual history of its own, the three fields are often operating in their own separate policy spheres and scholarly communities. It is the explicit aim of the War, Peace and Justice research group to advance an integrated approach to examining major interlinkages and innovative questions at the intersection of all three concepts and policy fields, which holds promise for producing innovative insights and answers based on a strong dialogue between the three pillars. Particular emphasis will also be placed on the role of gender, peace and security.


Teaching excellence is one of the core functions of the War, Peace and Justice (WPJ) research group. WPJ members engage in diverse forms of public engagement, but all share a commitment to education. Our classrooms are not simply places to teach but venues for staff and students to learn together. The WPJ group includes both theoretical and practical experts, with expertise ranging from the history of ideas to the practical conduct of war, peace, and justice today. The primary pedagogical venue for WPJ members is the War and Peace Studies track within the Crisis and Security Management Master’s programme. Members also teach across the Institute of Security and Global Affairs (ISGA), including the Bachelor Security Studies, several of the Institute’s minor programmes, and the advanced Master in International Relations and Diplomacy, and provide doctoral supervision.
