Review Questions

• How did the idea of Manifest Destiny influence the decision to annex Texas?
  • The idea of Manifest Destiny was a driving force behind the annexation of Texas, as many Americans believed it was their God-given right to expand westward across North America. This belief justified not only territorial acquisition but also the idea that American culture and democracy should spread to other areas. Supporters of annexation argued that bringing Texas into the Union would fulfill this destiny, even as it raised questions about the future of slavery in those territories.
• Discuss the political ramifications of Texas's annexation on U.S.-Mexico relations leading up to the Mexican-American War.
  • The political ramifications of Texas's annexation were profound, as Mexico viewed the act as an invasion and a blatant disregard for its territorial integrity. The U.S. government's decision to incorporate Texas heightened existing tensions and led to diplomatic disputes over border definitions, particularly concerning whether the Rio Grande or Nueces River constituted the border. These escalating tensions ultimately resulted in armed conflict, as Mexico refused to recognize Texas's independence and saw its annexation as an act of war.
• Evaluate how the annexation of Texas contributed to sectional tensions within the United States during this period.
  • The annexation of Texas significantly contributed to sectional tensions within the United States, primarily over the issue of slavery. Many Southern politicians supported annexation because it promised to add another slave state to the Union, thus maintaining a balance in Congress between free and slave states. Conversely, abolitionists and many Northern politicians opposed it, fearing that expanding slave territory would hinder efforts towards emancipation. This division intensified political conflict and laid groundwork for future confrontations leading up to the Civil War.
