Review Questions

• How did the Louisiana Purchase influence the presidency of Thomas Jefferson and his vision for America?
  • The Louisiana Purchase significantly shaped Thomas Jefferson's presidency by aligning with his vision of an agrarian society that expanded westward. Jefferson believed that a nation of independent farmers would sustain democracy and civic virtue. The acquisition allowed him to realize this vision by providing vast tracts of land for settlement, although it also posed a constitutional dilemma since such a purchase wasn't explicitly authorized by the Constitution.
• Analyze how the Louisiana Purchase contributed to the concept of Manifest Destiny in the 19th century.
  • The Louisiana Purchase served as a foundation for Manifest Destiny by providing a massive expanse of land that Americans believed was their right to occupy and cultivate. This belief in destiny fueled westward expansion efforts, asserting that American democracy and civilization should spread across North America. The newly acquired territory not only facilitated settlement but also intensified debates about slavery and governance as states were formed from these lands.
• Evaluate the long-term effects of the Louisiana Purchase on Native American populations and U.S. territorial policy.
  • The Louisiana Purchase had profound long-term effects on Native American populations, leading to significant displacement and conflict as settlers moved into their territories. U.S. territorial policy increasingly favored expansion at any cost, resulting in treaties that were often unfairly negotiated or outright ignored. This set a precedent for future policies that marginalized Native Americans, further entrenching conflicts over land rights and sovereignty that would last for generations.
