Coups d’état continue to present one of the most extreme risks to democracy and stable governance worldwide. This book examines the unique role played by regional organisations (ROs) following the occurrence of a coup d’état.The book analyses which factors influence the strength of reactions demonstrated by ROs and explores which different post-coup solutions ROs pursue. It argues that, when confronted with a coup, ROs take both basic democratic standards and regional stability into account before forming their responses.Using a mixed methods approach, the book concludes that ROs respond more decisively to a coup based on how detrimental it will be for the state of democracy in a country, and the higher its risk of destabilizing the region.
