Review Questions

  • How did the ideology of Manifest Destiny influence U.S. foreign policy in the 19th century?
    • Manifest Destiny significantly influenced U.S. foreign policy by promoting the idea that territorial expansion was not only desirable but also a moral duty. This led to aggressive actions like the annexation of Texas and conflicts such as the Mexican-American War. The belief in expansion shaped negotiations and treaties, as policymakers sought to acquire more land for farming, settlement, and resources under the notion that it was America's destiny to spread its values.
  • Analyze how Manifest Destiny contributed to tensions regarding slavery in newly acquired territories.
    • Manifest Destiny intensified tensions over slavery as new territories were acquired through westward expansion. As settlers moved into these lands, debates arose about whether they would permit slavery or be free states. This conflict led to events like the Compromise of 1850 and increased sectionalism between the North and South. The ideology's drive for expansion thus became entangled with issues of slavery, ultimately contributing to the conditions leading up to the Civil War.
  • Evaluate the impact of Manifest Destiny on indigenous populations and their resistance during westward expansion.
    • The impact of Manifest Destiny on indigenous populations was devastating, as it justified their displacement and removal from ancestral lands. As settlers moved westward, tribes faced violent conflicts, forced relocations like the Trail of Tears, and efforts to assimilate into American culture. Despite this oppression, many indigenous groups resisted through various means, including armed conflict and legal challenges. The clash between Manifest Destiny supporters and indigenous peoples highlighted significant moral contradictions in American expansionism and raised questions about rights and sovereignty that continue to resonate today.
