Argentina in World War I represents a fascinating case study in international diplomacy and domestic policy during a turbulent global conflict. While the nation remained officially neutral for the majority of the war, its strategic location, economic power, and substantial immigrant population created a complex and significant relationship with the Great War. From the initial declaration of neutrality in 1914 to the eventual severance of ties with the Central Powers in 1917, Argentina navigated a difficult path between its deep European ties and emerging national interests.
Initial Neutrality and Economic Considerations
The declaration of war in July 1914 was met with immediate official neutrality by the Argentine government. This stance was largely driven by pragmatic economic calculations rather than strict political alignment. European powers, particularly Britain and France, were crucial trading partners, but the United States and other American markets were equally vital for Argentine beef and grain exports. Entering the war would have inevitably disrupted these essential agricultural shipments, causing severe economic hardship. The government, led by President Victorino de la Plaza, prioritized maintaining the flow of commerce above aligning with either the Allied or Central Powers blocs.
The Domestic Dilemma: A Divided Population
Neutrality did not equate to unity or disinterest within Argentine society. The population was deeply split, reflecting the country's massive European immigration. Communities of British, French, and Italian descent generally sympathized with the Allies, viewing Germany as the aggressor. Conversely, populations of German and Austro-Hungarian origin often felt a cultural kinship with the Central Powers or simply wished to avoid taking sides in a distant conflict. This internal division created a volatile social atmosphere, where patriotic rallies for one side were often met with suspicion or hostility from the other, forcing the government to walk a tightrope to prevent civil unrest.
Diplomatic Tensions and the Sussex Incident
Despite the official policy, diplomatic relations with the Allied powers were frequently strained. The British Royal Navy's enforcement of a strict naval blockade created significant friction, as it impeded Argentina's ability to trade with German ports. A major turning point occurred in 1916 with the "Sussex incident." German U-boats sank the French passenger ferry SS Sussex, which was carrying Argentine nationals. The outrage in Argentina was immediate and profound, severely damaging relations with Germany and shifting the national conversation. The incident highlighted the precarious position Argentina found itself in, where the actions of a foreign power directly threatened its citizens and sovereignty.
Drifting Toward War
The sinking of the Sussex marked a significant shift in Argentina's posture. While full declaration of war was not immediate, the government's tolerance for German actions evaporated. Diplomatic pressures increased, including the severing of consular relations and the expulsion of suspected German spies. The prolonged strain of neutrality, combined with the moral outrage from the Sussex incident and the growing likelihood of an Allied victory, eroded the foundations of the initial neutral stance. The economic argument for neutrality was slowly being overshadowed by the political and social realities of the war's progression.
Breaking of Relations and Entry into War
The definitive break came in early 1917. The interception and publication of the Zimmermann Telegram, in which Germany proposed a military alliance with Mexico against the United States, outraged the international community. Although Argentina was not the direct target, the telegram confirmed aggressive German intentions and undermined any remaining trust. Shortly thereafter, in February 1917, Argentina severed diplomatic relations with Germany. This decisive action was followed by a formal declaration of war in July of the same year, officially aligning the nation with the Allied cause after nearly three years of neutrality.
