The Organization of American States is the oldest regional organization in the world, which dates back to the First International Conference of American States, held in Washington, D.C., from October 1889 to April 1890.
In this meeting, it was agreed to create the International Union of American Republics and began to weave a network of provisions and institutions that would come to be known as "inter-American system", the oldest international institutional system.
The OAS was created in 1948 when the OAS Charter was signed in Bogotá, Colombia in December 1951. The Charter was subsequently amended by the Protocol of Buenos Aires signed in 1967 and in February 1970 by the Protocol of Cartagena de Indias.
The objective is to achieve in itsr member states, as stipulated in Article 1 of the Charter, "an order of peace and justice, to foster their solidarity, to strengthen their collaboration and to defend their sovereignty, territorial integrity and independence."
It currently brings together the 35 independent States of the Americas and constitutes the main governmental political, juridical and social forum in the Hemisphere. In addition, it has granted the status of Permanent Observer to 69 States, as well as to the European Union (EU).
Its main pillars are democracy, human rights, security and development.
