Describe the establishment of the OAS.

The Organization of American States (OAS) was established on April 30, 1948, with the signing of the Charter of the Organization of American States in Bogotá, Colombia. The founding members were 21 countries from the Americas who came together to promote regional cooperation and mutual defense.

The OAS was created in response to the growing threats of communism and the need for a collective security organization in the Western Hemisphere. The organization's primary goals include promoting democracy, human rights, security, and development in the region.

The establishment of the OAS marked a significant moment in the history of the Americas, as it represented a commitment by member states to work together to address common challenges and promote peace and stability in the region. The organization has since expanded to include all 35 independent states in the Americas and continues to play a pivotal role in regional cooperation and diplomacy.
