The Organization of American States (OAS) is the oldest regional organization in the world. The foundations of the organization can be tracked back to the First International Conference of American, held in Washington, D.C., from October 1889 to April 1890. However, the OAS was officially established in 1948 with the signing of the Charter of the Organization of American states that entered into force later in December 1951. Currently, the Organization is formed by 35 independent states of the Americas and it constitutes juridical, social and political governmental forum in the Hemisphere.
The OAS was created with the purposes of promoting solidarity, strengthening collaboration, and defending sovereignty, integrity and independence of its member states. Furthermore, the Organization uses a four-pronged approach in order to implement its vital goals, which are built on four major pillars: democracy, human rights, security, and development.
