By combining comparative politics, conflict analysis and international relations theory Soeren Keil offers a unique analysis of federalism in post-Dayton Bosnia and Herzegovina. By exploring this model of ‘imposed federalism’ not only does this study greatly contribute to the literature on developments in Bosnia and Herzegovina it also re-evaluates comparative federalism in theory and practice. This study also offers important conclusions for similar cases, both in the Western Balkans region and the wider world, where international involvement and federalism as a method of conflict resolution in diverse societies becomes ever more prevalent and important.
