Review Questions

  • How did Manifest Destiny influence United States Colonization during the 19th century?
    • Manifest Destiny was a key ideological driver behind United States Colonization, promoting the belief that Americans were destined to expand across North America.

    • The Homestead Act significantly impacted migration patterns by incentivizing settlers to move westward into newly acquired lands. By offering 160 acres of land at a minimal cost, it attracted thousands seeking economic opportunities and a fresh start. This law facilitated rapid settlement in the West, contributing to demographic shifts as communities developed in areas previously inhabited by Native American tribes.

Additionally, expansionism prompted conflicts with countries such as Mexico, resulting in territorial gains but also fostering resentment that would affect U.S. foreign relations for years to come.
