Review Questions

• How did territorial gains from the Mexican–American War shape U.S. domestic policies in the years following the conflict?
  • Territorial gains from the Mexican–American War significantly influenced U.S. domestic policies by intensifying debates over slavery in newly acquired lands. As territories were integrated into the Union, questions arose regarding whether they would be free or slave states. This tension eventually led to key legislation such as the Compromise of 1850 and heightened sectional conflict that contributed to the outbreak of the Civil War.
• Evaluate the impact of the Treaty of Guadalupe Hidalgo on U.S.-Mexico relations and the rights of Mexican citizens after territorial gains were made.
  • The Treaty of Guadalupe Hidalgo had a profound impact on U.S.-Mexico relations as it formally ended hostilities but left lingering resentment and disputes over borders. While the treaty aimed to protect the rights of Mexican citizens in newly acquired territories by granting them U.S. citizenship and equal rights, many faced discrimination and were denied these protections. This complicated legacy has continued to affect bilateral relations between the two nations.
• Analyze how the concept of Manifest Destiny justified territorial gains during the 19th century and its consequences on indigenous populations.
  • Manifest Destiny was a driving ideology that justified territorial gains during the 19th century by promoting the belief that Americans were destined to expand across North America. This expansion often disregarded the rights and existence of indigenous populations, leading to displacement, violence, and cultural erasure. The pursuit of this belief not only shaped U.S. borders but also set a precedent for future interactions with Native American tribes and impacted their lives for generations.
