Review Questions

• How did the Missouri River influence the exploration strategies used by Lewis and Clark during their expedition?
  • The Missouri River was integral to Lewis and Clark's expedition as it served as their primary route into the uncharted western territories. By following the river upstream, they were able to access new areas and gather important scientific data about the land, resources, and indigenous peoples. The river's course helped determine their travel path, making navigation more feasible despite various challenges presented by rapids and changing conditions.
• Discuss the role of the Missouri River in promoting westward expansion following the Louisiana Purchase.
  • Following the Louisiana Purchase, the Missouri River became a key artery for westward expansion as it facilitated transportation of settlers and goods into newly acquired lands. Its vast network allowed for easier movement into regions that were previously difficult to access. This encouraged population growth along its banks and promoted agricultural development in surrounding areas, playing a significant role in shaping America's frontier life.
• Evaluate how the Missouri River's geographical features impacted both indigenous communities and European-American settlers during westward expansion.
  • The geographical features of the Missouri River significantly impacted both indigenous communities and European-American settlers. For indigenous peoples, the river provided essential resources such as fish, wildlife, and fertile land for agriculture. With European-American settlers arriving, they utilized the river for transportation and trade but often disregarded established indigenous land rights. The competition for resources led to conflicts while simultaneously transforming the landscape through settlement and development. Ultimately, these changes reshaped social dynamics in the region and altered traditional ways of life for many indigenous groups.
