U.S. Expansionism

Review Questions

• How did the ideology of Manifest Destiny influence U.S. expansionism and its impact on Latin America?
  • Manifest Destiny was a driving force behind U.S. expansionism, suggesting that Americans were divinely ordained to spread their values and institutions across the continent. This ideology justified actions such as territorial acquisitions and military interventions in Latin America, where the U.S. sought to extend its influence. As a result, many Latin American nations faced pressure to align with U.S. interests, often leading to tensions and conflicts over sovereignty and self-determination.
• Evaluate the implications of the Monroe Doctrine for U.S.-Latin American relations during the era of expansionism.
  • The Monroe Doctrine significantly shaped U.S.-Latin American relations by asserting that any European intervention in the Americas would be considered a direct threat to U.S. interests. This policy not only established U.S. dominance in the region but also fostered an environment where Latin American nations were often seen as satellites of U.S. power. The Doctrine allowed for increased American intervention in regional affairs, which sometimes resulted in both support for friendly governments and opposition against those perceived as hostile.
• Assess how U.S. expansionism shaped economic and political dynamics within Latin America during the 19th and early 20th centuries.
  • U.S. expansionism fundamentally altered economic and political dynamics in Latin America by increasing American influence over trade, investment, and governance. Through practices such as dollar diplomacy and military interventions, the U.S. sought to secure its interests in key markets and resources, which often undermined local autonomy. This created a legacy of dependency that influenced political alignments and social structures in various Latin American countries, leading to complex relationships characterized by both cooperation and resistance against perceived imperialistic actions.
