The Organization of American States (OAS) was founded in 1948 with the aim of promoting solidarity and cooperation among its member states within the Western Hemisphere. The OAS was established during the Ninth International Conference of American States held in Bogotá, Colombia, from March 30 to May 2, 1948. This conference was significant as it marked a pivotal moment in the history of inter-American relations and was attended by representatives from 21 American nations.

The charter signed at Bogotá established the OAS as the institution responsible for strengthening peace and security, consolidating representative democracy, promoting human rights, and fostering economic, social, and cultural development among its members. The creation of the OAS was influenced by the geopolitical context of the post-World War II era, where there was a strong desire to prevent future conflicts and to respond collectively to challenges affecting the region.

One of the cornerstone principles of the OAS is the commitment to democratic governance. The organization has played a crucial role in various diplomatic efforts, conflict resolutions, and election monitoring missions throughout the Americas. Over the years, it has adapted to the changing political landscape of the Western Hemisphere but has sometimes faced criticism over its effectiveness and impartiality, particularly in dealing with politically sensitive issues.

The establishment of the OAS in 1948 also marked the beginning of a more structured approach to political and economic cooperation in the Americas, laying the groundwork for future regional agreements and supporting the idea of Pan-Americanism.
