This study assesses the nature and dynamics of the international State restoration efforts undertaken in response to the phenomenon of State disintegration during the post-Cold War period. To this end, it analyzes how the process of recovering States from disintegration has emerged as a new role for the United Nations, and reviews the contribution of academics and practitioners to clarify both the phenomenon and the reaction. The study is structured in two parts: "Recovering States from Disintegration", and "An Emerging International Cooperative Framework for State Restoration". The first part analyzes State disintegration and the consequent reaction to reverse the phenomenon primarily through the United Nations, while the second examines the institutions and norms shaping an emerging international cooperative framework for State restoration
