Over the past several decades, democracy has taken root or been re-established in a number of countries with support from other democratic states and private groups. While the increase in the number of democracies worldwide has been widely heralded, very little has been written on how democracy can be protected and sustained where it has been chosen by the people of a state. In this first comprehensive guide to preventing and responding to threats to coups and erosions in democracies. Through case studies and in-depth analyses, this book provides legal and policy justification for these processes and discusses how they can be made more effective, combining the findings of an international task force on threats to democracy with contributions from leading scholars and policymakers.
