Review Questions

• How did the Louisiana Purchase impact U.S. foreign relations, particularly with France?
  • The Louisiana Purchase strengthened U.S. foreign relations by securing a vast territory while also diminishing French presence in North America. The sale was partly driven by Napoleon's need for funds during the Napoleonic Wars and his inability to maintain control over distant territories. This deal not only improved ties between the two nations but also positioned the U.S. as a rising power on the global stage, demonstrating its capacity to negotiate significant land acquisitions.
• Evaluate how the Louisiana Purchase influenced political debates over slavery and statehood in the United States.
  • The Louisiana Purchase intensified political debates over slavery as new territories were added to the U.S., raising questions about whether they would be free or slave states. This conflict led to significant political turmoil, illustrated by events like the Missouri Compromise of 1820, which attempted to balance the interests of slave and free states. The purchase set a precedent for expansion that would continue to provoke contentious debates surrounding sectionalism in America.
• Analyze how the acquisition of Louisiana contributed to the ideology of Manifest Destiny in the 19th century.
  • The Louisiana Purchase laid the groundwork for Manifest Destiny by dramatically expanding U.S. territory and fostering a belief that Americans were destined to spread across North America. This ideology emerged from the perception that it was both a right and responsibility of Americans to occupy and cultivate land, which encouraged westward migration and further territorial acquisitions throughout the century. The desire for expansion fueled conflicts with Native American tribes and brought issues of governance and morality into sharp relief as settlers moved into newly acquired regions.
