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., from October 1889 to April 1890. At that meeting the establishment of the International Union of American Republics was approved. The Charter of the OAS was signed in Bogota in 1948 and entered into force in December 1951. The Charter was subsequently amended by the Protocol of Buenos Aires, signed in 1967, which entered into force in February 1970; by the Protocol of Cartagena de Indias, signed in 1985, which entered into force in November 1988; by the Protocol of Managua, signed in 1993, which entered into force on January 29, 1996; and by the Protocol of Washington, signed in 1992, which entered into force on September 25, 1997. The OAS currently has 35 member states. In addition, the Organization has granted permanent observer status to over 43 states, as well as to the European Union.
The essential purposes of the OAS are: to strengthen peace and security in the Hemisphere; to promote and consolidate representative democracy, with due respect for the principle of nonintervention; to prevent possible causes of difficulties and to ensure peaceful settlement of disputes that may arise among the member states; to provide for common action on the part of those states in the event of aggression; to seek the solution of political, juridical, and economic problems that may arise among them; to promote, by cooperative action, their economic, social, and cultural development; and to achieve an effective limitation of conventional weapons that will make It possible to devote the largest amount of resources to the economic and social development of the member states.
