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.

From 1800 to the present, US troops have intervened thousands of times in Latin America and have occupied its countries on dozens of occasions. Interventions were short-term and superficial, while occupations lasted longer and controlled local governments. The causes of these troop landings reflected the United States’ motivations as it expanded from a strong, large republic into first a continental and then an overseas empire at the expense of its smaller, weaker neighbors. Those motivations included colonial land hunger, cultural chauvinism, the exploitation of resources, the search for markets abroad, competition against other great powers, political reformism, global ideological struggle, and the perception that US domestic problems originated in Latin America. US troops undertook almost all these interventions and occupations, although private groups sometimes joined. The major periods were the expansion of the continental republic from 1811 to 1897, the war in Cuba and the apex of occupations (1898–1933), the Good Neighbor years (1934–1953), the Cold War (1954–1990), and the post-Cold War period (1991–2018 and ongoing). Scholars of these events have become increasingly critical and diverse, not only seeing them often as unnecessary brutal failures but also foregrounding extra-military aspects of these episodes, such as economics, race, and gender.
U.S. foreign policy toward Latin America in the 19th century initially focused on excluding or limiting the military and economic influence of European powers, territorial expansion, and encouraging American commerce. These objectives were expressed in the No Transfer Principle (1811) and the Monroe Doctrine (1823). American policy was unilateralist (not isolationist); it gradually became more aggressive and interventionist as the idea of Manifest Destiny contributed to wars and military conflicts against indigenous peoples, France, Britain, Spain, and Mexico in the Western Hemisphere. Expansionist sentiments and U.S. domestic politics inspired annexationist impulses and filibuster expeditions to Mexico, Cuba, and parts of Central America. Civil war in the United States put a temporary halt to interventionism and imperial dreams in Latin America. From the 1870s until the end of the century, U.S. policy intensified efforts to establish political and military hegemony in the Western Hemisphere, including periodic naval interventions in the Caribbean and Central America, reaching even to Brazil in the 1890s. By the end of the century Secretary of State Richard Olney added the Olney Corollary to the Monroe Doctrine (“Today the United States is practically sovereign on this continent and its fiat is law upon the subjects to which it confines its interposition . . .”), and President Theodore Roosevelt contributed his own corollary in 1904 (“in the Western Hemisphere the adherence of the United States to the Monroe Doctrine may force the United States, however reluctantly, in flagrant cases of wrongdoing or impotence, to exercise an international police power”). American policy toward Latin America, at the turn of the century, explicitly justified unilateral intervention, military occupation, and transformation of sovereign states into political and economic protectorates in order to defend U.S. economic interests and an expanding concept of national security.
