This edited volume focuses on disentangling the interplay of local peacebuilding processes and international policy, via comparative theoretical and empirical work on the question of legitimacy and authority. Using a number of conflict-affected regions as case studies including Kosovo, Iraq, Bosnia-Herzegovina and Sudan the book incorporates the expertise of a range of international scholars in order to understand the dynamics of local peacebuilding, the construction of legitimate authority, and its interplay with internationally led peace- and state-building interventions. The commissioned chapters advance our understanding of local legitimacy, sustainable international engagement, and the hybrid forms of authority they produce.
