Review Questions
How did the idea of Manifest Destiny influence U.S. foreign policy during the mid-19th century?
Manifest Destiny significantly influenced U.S. foreign policy by justifying expansionist actions such as the annexation of Texas and the pursuit of territories from Mexico. The belief that it was America's divine right to expand led to aggressive negotiations and military engagements aimed at acquiring land. This mindset created a precedent for future interventions in foreign nations under the guise of spreading democracy and civilization.
In what ways did Manifest Destiny affect the relationship between different regions of the United States, particularly regarding slavery?
Manifest Destiny intensified regional tensions between the North and South as new territories were acquired. The question of whether these new lands would be free or slave states became a contentious issue, contributing to conflicts like the Missouri Compromise and the Compromise of 1850. This ideological divide exacerbated sectionalism, ultimately leading to increased polarization that would culminate in the Civil War.
Evaluate how Manifest Destiny contributed to both American expansion and the suffering of indigenous populations during this period.
Manifest Destiny fueled American expansion by promoting the notion that settlers had a right to occupy and cultivate lands westward. However, this expansion came at a grave cost to indigenous populations, who faced violent displacement, loss of land, and cultural erasure. As settlers encroached on their territories, many Native American tribes experienced devastating consequences, including broken treaties and forced removals, illustrating how this ideology fostered a narrative that prioritized American growth over human rights.
The belief that the United States is inherently different from other nations, often linked to the idea of a unique mission to spread democracy and freedom.
