Coups d'etat continue to present one of the most extreme risks to democracy and stable governance worldwide. This book examines the unique role played by regional organizations (ROs) following the occurrence of a coup d'etat. The book analyses the factors that influence the strength of reactions demonstrated by ROs and explores the 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' response to a coup depends on how detrimental it will be for the state of democracy in a country and how far it risks destabilizing the region.
