The United States Mission to the Organization of American States was formally established in 1948, and is the only embassy located within the Department of State in Washington, D.C. The Organization of American States (OAS) is the world’s oldest regional organization, dating back to the First International Conference of American States held in Washington, D.C. in October 1889. It is the premier multilateral forum for dealing with political issues in the Western Hemisphere. The main goals of the Mission are to strengthen peace and security, promote the effective exercise of representative democracy, ensure the peaceful settlement of disputes among members, and provide for common action in the event of aggression. They also seek solutions to political, juridical, and economic problems that may arise by promoting cooperative action, and economic, social, educational, scientific and cultural development.
