Review Questions

• How did Texas Annexation reflect the broader concept of Manifest Destiny during the mid-19th century?
  • Texas Annexation is a prime example of Manifest Destiny, which held that it was America's divine right to expand westward across North America. The desire for territorial expansion fueled support for annexing Texas, as many Americans believed it was their destiny to incorporate new lands into the U.S. This belief justified not only the acquisition of Texas but also contributed to escalating tensions with Mexico, leading to war.
