This path-breaking volume provides the first in-depth examination of the role security sector reforms in democratizing constitutional transitions, drawing on a rich set of case studies spanning Europe, South America, Africa, and Asia. The volume offers critical lessons for those interested in post-authoritarian democratic transitions, challenging the conventional wisdom that security services must always be kept out of transitional processes and identifying key roles they might play to ensure stability and enable effective civilian oversight. Evidence drawn from cross-regional comparison allows the editors to develop empirically-grounded theoretical insights in a concluding chapter that makes an incisive and original contribution to the growing literature on democratic transitions.
