Organization of American States: Background and Issues for Congress

The Organization of American States (OAS) is the oldest multilateral regional organization in the world. It was founded in 1948 by the United States and 20 Latin American nations to serve as a forum for addressing issues of mutual concern. Over time, the organization expanded to include all 35 independent countries of the Western Hemisphere (though Cuba currently does not participate). The organization’s areas of focus have also shifted over time, evolving in accordance with the priorities of its member states. Today, the OAS concentrates on four broad objectives: democracy promotion, human rights protection, economic and social development, and regional security cooperation. It carries out a wide variety of activities to advance these goals, often providing policy guidance and technical assistance to member states.
