This study provides a thorough assessment of the role and authority of the Organisation of American States as an International Organization (IO).

This book explores the extent and significance of the transformation of the Organisation of American States since 1991: its roots, the reasons for and extent of its emergence, and the role that the organisation currently plays in the promotion of regional governance in the two key issue-areas of security and the defense and promotion of democratic norms and principles of good governance. By assessing where the OAS has succeeded and failed, Horwitz provides an in-depth explanation of how cooperation and consensus works in the Inter-American system.
