The Organization of American States (Spanish: Organización de los Estados Americanos, Portuguese: Organização dos Estados Americanos, French: Organisation des États américains), or the OAS or OEA, is a continental organization that was founded on 30 April 1948, for the purposes of solidarity and cooperation among its member states within the Western Hemisphere. During the Cold War, the United States hoped the OAS would be a bulwark against the spread of communism.[1] Since the 1990s, the organization has focused on election monitoring. Headquartered in the United States' capital Washington, D.C., the OAS's members are the 35 independent states of the Americas.

As of 26 May 2015, the Secretary General of OAS is Luis Almagro.[2]


The Pan American Union shortly after its construction in 1910

The notion of an international union in the New World was first put forward during the liberation of the Americas by José de San Martín and Simón Bolívar[3] who, at the 1826 Congress of Panama (still being part of Colombia), proposed creating a league of American republics, with a common military, a mutual defense pact, and a supranational parliamentary assembly. This meeting was attended by representatives of Gran Colombia (comprising the modern-day countries of Colombia, Ecuador, Panama and Venezuela), Argentina, Peru, Bolivia, The United Provinces of Central America, and Mexico but the grandly titled "Treaty of Union, League, and Perpetual Confederation" was ultimately ratified only by Gran Colombia. Bolívar's dream soon floundered with civil war in Gran Colombia, the disintegration of Central America, and the emergence of national rather than New World outlooks in the newly independent American republics. Bolívar's dream of American unity was meant to unify Hispanic American nations against external powers.

The pursuit of regional solidarity and cooperation again came to the forefront in 1889–1890, at the First International Conference of American States. Gathered together in Washington, D.C., 18 nations resolved to found the International Union of American Republics, served by a permanent secretariat called the Commercial Bureau of the American Republics (renamed the International Commercial Bureau at the Second International Conference in 1901–1902). These two bodies, in existence as of 14 April 1890, represent the point of inception to which the OAS and its General Secretariat trace their origins.

At the fourth International Conference of American States (Buenos Aires, 1910), the name of the organization was changed to the Union of American Republics and the Bureau became the Pan American Union. The Pan American Union Building was constructed in 1910, on Constitution Avenue, Northwest, Washington, D.C.

In the mid-1930s, U.S. President Franklin Delano Roosevelt organized an inter-American conference in Buenos Aires. One of the items at the conference was a "League of Nations of the Americas", an idea proposed by Colombia, Guatemala, and the Dominican Republic.[4] At the subsequent Inter-American Conference for the Maintenance of Peace, 21 nations pledged to remain neutral in the event of a conflict between any two members.[5] The experience of World War II convinced hemispheric governments that unilateral action could not ensure the territorial integrity of the American nations in the event of external aggression. To meet the challenges of global conflict in the postwar world and to contain conflicts within the hemisphere, they adopted a system of collective security, the Inter-American Treaty of Reciprocal Assistance (Rio Treaty) signed in 1947 in Rio de Janeiro.

The ninth International Conference of American States was held in Bogotá between March and May 1948 and led by United States Secretary of State George Marshall, a meeting which led to a pledge by members to fight communism in the western hemisphere.[6] This was the event that saw the birth of the OAS as it stands today, with the signature by 21 American countries of the Charter of the Organization of American States on 30 April 1948 (in effect since December 1951). The meeting also adopted the American Declaration of the Rights and Duties of Man, the world's first general human rights instrument.

The transition from the Pan American Union to OAS would have been smooth if it had not been for the assassination of Colombian leader Jorge Eliécer Gaitán. The Director General of the former, Alberto Lleras Camargo, became the Organization's first Secretary General. The current Secretary General is former Uruguayan minister of foreign affairs Luis Almagro.

Significant milestones in the history of the OAS since the signing of the Charter have included the following:

Goals and purpose

In the words of Article 1 of the Charter, the goal of the member nations in creating the OAS was "to achieve an order of peace and justice, to promote their solidarity, to strengthen their collaboration, and to defend their sovereignty, their territorial integrity, and their independence." Article 2 then defines eight essential purposes:

Over the course of the 1990s, with the end of the Cold War, the return to democracy in Latin America, and the thrust toward globalization, the OAS made major efforts to reinvent itself to fit the new context. Its stated priorities now include the following:

Organizational structure

US Secretary of State Mike Pompeo speaks at the OAS Permanent Council in January 2019

The Organization of American States is composed of an Organization of American States General Secretariat, the Permanent Council, the Inter-American Council for Integral Development, and a number of committees.

The General Secretariat of the Organization of American States consists of six secretariats.

The various committees of the Organization of American States include:

The various commissions of the Organization of American States include:


The OAS has two funds, one for the General Secretariat, and one for specific programs and initiatives. The General Assembly asks for contributions from each member country based on its capacity to pay. In 2018 the General Secretariat's budget was $85 million of which the US contributed $50 million. In 2017 the US contributed $17 million to the fund for specific programmes which was almost a third of the total contributions for that year.[13]

General Assembly

The General Assembly is the supreme decision-making body of OAS. It convenes once every year in a regular session. In special circumstances, and with the approval of two-thirds of the member states, the Permanent Council can convene special sessions.

The Organization's member states take turns hosting the General Assembly on a rotating basis. The states are represented at its sessions by their chosen delegates: generally, their ministers of foreign affairs, or their appointed deputies. Each state has one vote, and most matters—except for those for which the Charter or the General Assembly's own rules of procedure specifically require a two-thirds majority—are settled by a simple majority vote.

The General Assembly's powers include setting the OAS's general course and policies by means of resolutions and declarations; approving its budget and determining the contributions payable by the member states; approving the reports and previous year's actions of the OAS's specialized agencies; and electing members to serve on those agencies.

Membership and adhesions

All 35 independent nations of the Americas are members of the OAS. Upon foundation in 1948, there were 21 members, most of them in Latin America:

The later expansion of the OAS included Canada and the newly independent nations of the Caribbean. Members with later admission dates (sorted chronologically):


  1. ^ a b On 28 April 2017 Venezuela notified the OAS of its denunciation of the Charter of the OAS, which as per Article 143 would lead to the withdraw of Venezuela from the OAS effective two years from the date of notification.[17] During the 2019 Venezuelan presidential crisis, the President of the National Assembly of Venezuela Juan Guaidó, who was recognized by the National Assembly as the acting president, sent a letter to the OAS Secretary General annuling the previous denuncation of the OAS Charter, and expressing his desire for Venezuela to remain a member of the OAS.[17] The National Assembly designated a special envoy as representative to the OAS, who the OAS voted to recognize as Venezuela's delegate in April.[18][19]
  2. ^ Suspended between 1962–2009.[14] Has chosen not to resume their participation.[15] See Status of Cuba below.
  3. ^ Suspended between 2009–2011.[16] See Suspension of Honduras below.

Canada and the OAS

Although Canada was a founding member of the League of Nations in 1919[20] and has joined international organizations since that date, it chose not to join the OAS when it was first formed, despite its close relations with the United States. Canada became a Permanent Observer in the OAS on 2 February 1972. Canada signed the Charter of the Organization of American States on 13 November 1989 and this decision was ratified on 8 January 1990.

In 2004–2005, Canada was the second largest contributor to the OAS, with an annual assessed contribution representing 12.36 percent of the OAS Regular Budget (US$9.2 million) and an additional C$9 million in voluntary contributions to specific projects.[21][22] Shortly after joining as a full member, Canada was instrumental in the creation of the Unit for the Promotion of Democracy, which provides support for the strengthening and consolidation of democratic processes and institutions in OAS member states.[23]

Sanctions against the Dominican Republic

During the 6th Conference of Foreign Ministers of the Organization of American States (OAS) in Costa Rica, from 16 to 20 August 1960, a conviction against the State of the Dominican Republic was agreed to unanimously. The penalty was motivated because the foreign ministers checked the veracity of the claim that the Rafael Trujillo regime had sponsored an attack against Rómulo Betancourt, at that time, constitutional president of Venezuela. The meeting was attended by foreign ministers from 21 American nations, including Cuba, which at that time had not yet been expelled from the inter-American system.

All countries, including the United States and Haiti, broke off diplomatic relations with the Dominican Republic. Additionally an economic blockade that affected the exports of sugar was applied, which at that time was the pillar of the Dominican economy.

It was the first application of the Inter-American Treaty of Reciprocal Assistance, which had been adopted at the OAS on July 29, 1960.

Status of Cuba

The current government of Cuba was excluded from participation in the Organization under a decision adopted by the Eighth Meeting of Consultation in Punta del Este, Uruguay, on 31 January 1962. The vote was passed by 14 in favor, with one against (Cuba) and six abstentions (Argentina, Bolivia, Brazil, Chile, Ecuador, and Mexico). The operative part of the resolution reads as follows:

#That adherence by any member of the Organization of American States to Marxism-Leninism is incompatible with the inter-American system and the alignment of such a government with the communist bloc breaks the unity and solidarity of the continents.

  1. That the present Government of Cuba, which has officially identified itself as a Marxist-Leninist government, was incompatible with the principles and objectives of the inter-American system.
  2. That this incompatibility excluded the present Government of Cuba from participation in the inter-American system.[24]

This meant that the Cuban nation was still technically a member state, but that the current government was denied the right of representation and attendance at meetings and of participation in activities. The OAS's position was that although Cuba's participation was suspended, its obligations under the Charter, the American Declaration of the Rights and Duties of Man, etc. still hold: for instance, the Inter-American Commission on Human Rights continued to publish reports on Cuba's human rights situation and to hear individual cases involving Cuban nationals. However, this stance was occasionally questioned by other individual member states.

Cuba's position was stated in an official note sent to the Organization "merely as a courtesy" by Minister of Foreign Affairs Dr. Raúl Roa on 4 November 1964: "Cuba was arbitrarily excluded ... The Organization of American States has no juridical, factual, or moral jurisdiction, nor competence, over a state which it has illegally deprived of its rights."[25]

The reincorporation of Cuba as an active member regularly arose as a topic within the inter-American system – for instance, it was intimated by the outgoing ambassador of Mexico in 1998[26] – but most observers did not see it as a serious possibility while the present government remained in power. Since 1960, the Cuban administration had repeatedly characterized the OAS as the "Ministry of Colonies" of the United States of America.[27][28] On 6 May 2005, President Fidel Castro reiterated that the island nation would not "be part of a disgraceful institution that has only humiliated the honor of Latin American nations."[29] After Fidel Castro's recent retirement and the ascent of his brother Raúl to power, this official position was reasserted. Venezuelan President Hugo Chávez promised to veto any final declaration of the 2009 Summit of the Americas due to Cuba's exclusion.[30]

On 17 April 2009, after a "trading of warm words" between the administrations of U.S. President Barack Obama and Cuban leader Raúl Castro, OAS Secretary General José Miguel Insulza said he would ask the 2009 General Assembly to annul the 1962 resolution excluding Cuba.[31]

On 3 June 2009, foreign ministers assembled in San Pedro Sula, Honduras, for the OAS's 39th General Assembly, passed a vote to lift Cuba's suspension from the OAS. The United States had been pressuring the OAS for weeks to condition Cuba's readmission to the group on democratic principles and commitment to human rights. Ecuador's Foreign Minister Fander Falconí said there will be no such conditions. "This is a new proposal, it has no conditions—of any kind," Falconí said. "That suspension was made in the Cold War, in the language of the Cold War. What we have done here is fix a historic error."[32] The suspension was lifted at the end of the General Assembly, but, to be readmitted to the Organization, Cuba will need to comply with all the treaties signed by the Member States, including the Inter-American Democratic Charter of 2001.[33] A statement issued by the Cuban government on 8 June 2009 stated that while Cuba welcomed the Assembly's gesture, in light of the Organization's historical record "Cuba will not return to the OAS."[34]

Suspension of Honduras (2009–2011)

Those attending the Extraordinary Assembly of the OAS voted to suspend Honduras.

Following the expulsion of its President Manuel Zelaya, Honduras' membership of the Organization was suspended unanimously at midnight on 5 July 2009.[35] The de facto government had already announced it was leaving the OAS hours earlier; this was not, however, taken into account by the OAS, which did not recognize that government as legitimate.[36] An extraordinary meeting had been conducted by the OAS in Washington, D.C., with Zelaya in attendance.[35][37][38] The suspension of Honduras was approved unanimously with 33 votes (Honduras did not vote).[35][38] This was the first suspension carried out by the OAS since that of Cuba in 1962.[35][38]

After Zelaya's return to Honduras in 2011, the country was re-admitted to the Organization on 1 June 2011 with 32 votes in favor and 1 (Ecuador) against. Venezuela expressed some reservations.[39]

Status of Venezuela

On 28 April 2017 Venezuela notified the OAS of its denunciation of the Charter of the OAS, which as per Article 143 would lead to the withdrawal of Venezuela from the OAS effective two years from the date of notification.[17] During this period, the country did not plan on participating in the OAS.[40]

During the 2019 Venezuelan presidential crisis, the President of the National Assembly of Venezuela Juan Guaidó, who was recognized by the National Assembly as the acting president, sent a letter to the OAS Secretary General annulling the previous denunciation of the OAS Charter, and expressing his desire for Venezuela to remain a member of the OAS.[17] The National Assembly designated a special envoy as representative to the OAS, lawyer Gustavo Tarre Briceño, who the OAS voted to recognize as Venezuela's delegate in April.[18][19][41]

Permanent observers

As of 31 January 2014, there are 69 permanent observer countries including the four countries with territory or territories in the Americas—Denmark, France, the Netherlands, and the United Kingdom; as well as the European Union.[42][43][44]

Official languages

The Organization's official languages are Spanish, Portuguese, French, and English. The Charter, the basic instrument governing OAS, makes no reference to the use of official languages. These references are to be found in the Rules of Procedure governing the various OAS bodies. Article 51 of the Rules of Procedure of the General Assembly,[45] the supreme body of the OAS, which meets once a year, states that English, French, Portuguese, and Spanish are the four official languages. Article 28 stipulates that a Style Committee shall be set up with representatives of the four official languages to review the General Assembly resolutions and declarations. Article 53 states that proposals shall be presented in the four official languages. The Rules of Procedure and Statutes of other bodies, such as the Inter-American Council for Integral Development (CIDI), the Permanent Executive Committee of the Inter-American Council for Integral Development (CEPCIDI), the Inter-American Commission of Women (CIM), the Inter-American Drug Abuse Control Commission (CICAD), the Inter-American Commission on Human Rights (IACHR) and the Inter-American Juridical Committee (CJI), technical bodies of the OAS, also mention the four official languages in which their meetings are to be conducted. Policy is therefore dictated through these instruments that require use of the four official languages at meetings.[46]

Although a number of other languages have official status in one or more member states of OAS (Dutch in Suriname; Haitian Creole alongside French in Haiti; Quechua and Aymara in Peru, Ecuador and Bolivia; Guaraní in Paraguay), they are not official languages of the Organization.
