Organization of American States (OAS)

Abstract

Origin. On 14 April 1890 representatives of the American republics, meeting in Washington at the First International Conference of American States, established an International Union of American Republics and, as its central office, a Commercial Bureau of American Republics, which later became the Pan-American Union. This international organization’s object was to foster mutual understanding and co-operation among the nations of the western hemisphere. This led to the adoption on 30 April 1948 by the Ninth International Conference of American States, at Bogota, Colombia, of the Charter of the Organization of American States. This co-ordinated the work of all the former independent official entities in the inter-American system and defined their mutual relationships. The Charter of 1948 was subsequently amended by the Protocol of Buenos Aires (1967) and the Protocol of Cartagena de Indias (1985).
