1910–1945

Although on a lesser scale than the United States, southern South America became a major receiving region during the period of mass transatlantic migration in the late 19th and early 20th centuries. Even as the white elites of most Latin American countries favored European immigration in the late 19th century, since in their eyes it would “civilize” their countries, it was the temperate areas closely tied into the Atlantic economy as exporters of primary products that received the bulk of European laborers. Previously scarcely populated lands like Argentina, Uruguay, and southern Brazil thus witnessed massive population growth and in some ways turned into societies resembling those of other immigration countries, such as the United States and Canada. This article concentrates on lands where the overwhelming majority of migrants headed, although it also briefly deals with Latin American nations that received significantly fewer newcomers, such as Mexico.

This mass migration lastingly modified identity narratives within Latin America. First, as the majority of Europeans headed to sparsely populated former colonial peripheries that promised economic betterment, migration shifted prevalent notions about the region’s racial composition. The former colonial heartlands of Mexico, Peru, and northeastern Brazil were increasingly regarded as nonwhite, poor, and “backward,” whereas coastal Argentina, São Paulo, and Costa Rica were associated with whiteness, wealth, and “progress.” Second, mass migration was capable of both solidifying and challenging notions of national identity. Rather than crossing over well-established and undisputed boundaries of national identities and territories, migration thus contributed decisively to making them.

At the moment of its founding in 1920, the League of Nations enjoyed the solid support of Latin American countries, whose early and extensive participation helped legitimize the new international system and facilitate the functioning of its institutional representation. While this support was tremendously valuable for the Geneva-based League, it continuously suffered temporary, though significant, lapses on the part of nations that were particularly representative of the region, such as Argentina, Brazil and Mexico. Despite the characteristically pacifist rhetoric enunciated by this group of states, Latin American support cannot be called disinterested or sincere. Indeed, their collaboration with the multilateral and universalistic pretensions of the League was notoriously reserved, to such an extent that in the 1920s the organization’s General Secretariat granted them special treatment and prerogatives, while simultaneously ensuring that the League would continue to exert its influence in the Western Hemisphere. This reality was confirmed, sadly, in the context of two conflicts, the Chaco and Leticia wars, during which Latin American loyalty to the League became seriously questioned. With few exceptions in the decade that followed—one characterized by complicated crises that would lead to a new worldwide conflagration—the general tendency with respect to the system of collective security described in the Society’s Charter was scarred by dissatisfaction, incompliance, and increasing disillusionment that undoubtedly contributed to the weakening and eventual collapse of this organization so emblematic of the interwar period.
