This book examines the African Union Convention on the Protection and Assistance of Internally Displaced Persons - known as the Kampala Convention - which entered into force on 6 December 2012. The book sets out the shortcomings of international law relating to internal displacement, more specifically the 'protection gap'. The author shows how the Kampala Convention not only fills this protection gap, but also how it contributes to the overall development of norms in international, regional and national laws governing internal displacement. The book is of interest to scholars of international law and human rights, as well as to experts in peace and security and practitioners in humanitarian organizations, the African Union, the United Nations, and Regional Economic Communities.
