ABC Conference (1917) was a 1917 diplomatic meeting convened by the South American powers Argentina, Brazil, and Chile to address a maritime and territorial crisis involving regional and extra-hemispheric actors. The gathering sought to mediate disputes among states and to influence wartime alignments during the First World War era by assembling envoys from Latin American republics, European legations, and neutral governments. Delegates debated arbitration mechanisms, naval incidents, and commercial rights, producing protocols that shaped inter-American diplomacy and influenced later multilateral forums.

Background and context

The conference emerged against a backdrop of the First World War, the United Kingdom's naval blockade, the German Empire's U-boat campaign, and tensions in the South Atlantic Ocean, occasioned by incidents implicating Argentina, Brazil, and Chile. Regional crises recalled precedents such as the Algeciras Conference and the Hague Conventions, while contemporary diplomacy referenced the Pan-American Union and earlier mediated settlements like the Behring Sea Arbitration and the Pact of Bogotá. Latin American foreign ministries feared spillover from European belligerence and sought to assert the Monroe Doctrine's hemisphere claims alongside principles advanced at the Second Hague Conference and in discussions at the Washington Naval Conference planning circles.

Participants and delegations

Principal mediators were the foreign ministries of Argentina, Brazil, and Chile, whose envoys represented the ABC mechanism that had previously convened in other crises. Observers and participants included legations from the United States, the United Kingdom, the French Third Republic, the German Empire, and neutral states such as Spain, Switzerland, and Portugal. Prominent diplomats present had previously served at the Congress of Vienna successor institutions or in missions to the League of Nations founders—figures connected to the diplomatic careers of envoys who had posted to the United States Department of State, the Foreign Office (United Kingdom), and the Ministry of Foreign Affairs (France). Naval attachés from the Royal Navy, the Imperial German Navy, and the United States Navy attended in consultative capacities.

Agenda and key issues

The agenda prioritized maritime incidents between merchant vessels, questions of contraband, and the status of belligerent warships in neutral ports, invoking earlier jurisprudence such as rulings from the International Court of Justice predecessors and arbitral awards like the Alabama Claims settlement. Delegates debated territorial claims, commercial access for exporters to the United Kingdom and Germany, and the protection of nationals amid wartime internments drawing analogies to the Treaty of Utrecht and regional arbitration examples like the Arbitration between Chile and Argentina. Proposals included codifying neutral port rights, defining contraband lists, and mechanisms for third-party arbitration modeled on the Permanent Court of Arbitration.

Proceedings and negotiations

Negotiations unfolded in plenary sessions, caucuses, and bilateral meetings among the ABC powers, with procedural rules influenced by practices from the Conference of Paris (1919) and diplomatic norms observed at the Congress of Berlin (1878). Debates often referenced legal arguments derived from scholars who had advised delegations at the Hague Peace Conferences. Positions hardened on contraband classification, while conciliatory drafts incorporated language from treaties such as the Treaty of Paris (1814). Mediators leveraged precedents from the Rio Protocol style settlements and invoked arbitration clauses akin to those used in the U.S.–Mexico General Claims Commission.

Outcomes and agreements

The conference produced protocols on neutral rights at sea, a framework for arbitration of maritime disputes, and confidence-building measures for merchant shipping, echoing principles later echoed by the League of Nations Covenant and postwar naval treaties. Documents recommended that incidents be submitted to an arbitral tribunal with procedural features resembling the Permanent Court of Arbitration roster and included commitments by Argentina, Brazil, and Chile to coordinate diplomatic responses. Several resolutions urged belligerent powers to respect neutral commerce and to use established diplomatic channels such as the Pan-American Union to resolve claims. While not a treaty in the classic sense, the protocols influenced bilateral notes and memoranda exchanged with the United States and the United Kingdom.

Immediate aftermath and reactions

Reactions ranged from cautious approval among Latin American press organs that echoed editorials in capitals like Buenos Aires, Rio de Janeiro, and Santiago to skepticism voiced by representatives of the German Empire and the Austro-Hungarian Empire concerned about constraints on naval operations. The United States government and delegations in Washington, D.C. commented on the conference as a regional effort consistent with pan-American diplomacy. Merchants in ports such as Valparaíso and Montevideo adjusted shipping practices in line with the new protocols, while navies issued orders aligning with arbitration recommendations.

Historical significance and legacy

Historically, the ABC Conference of 1917 is regarded as a key instance of Latin American multilateral diplomacy that presaged later regional mechanisms like the Rio Treaty and contributed to the development of norms later embodied in the United Nations and the Inter-American Treaty of Reciprocal Assistance. Its arbitration framework informed jurisprudence at emergent international institutions, influencing disputes resolved by the International Court of Justice and regional arbitration commissions. The conference bolstered the diplomatic prestige of Argentina, Brazil, and Chile as mediators, shaping inter-American relations and the evolution of neutrality law in the early twentieth century.
