Review Questions
How did economic factors influence expansionism in the United States during the 19th century?
Economic factors played a crucial role in shaping expansionism in the United States as the nation sought new markets and resources to fuel its growing economy. The desire for agricultural land pushed settlers westward, while industrial growth created a demand for raw materials. This pursuit of economic opportunity often justified territorial expansion and led to conflicts with Indigenous peoples who occupied these lands.
Evaluate the impact of Manifest Destiny on U.S. foreign policy and relations with neighboring countries during the 19th century.
Manifest Destiny significantly shaped U.S. foreign policy by legitimizing territorial expansion as a national mission. This belief influenced diplomatic relations with neighboring countries, particularly Mexico, as seen in events like the Texas annexation and the Mexican-American War. The U.S. justified aggressive actions under this ideology, which not only altered boundaries but also affected international perceptions of American intentions.
Assess how expansionism affected Native American communities and their resistance movements during the 19th century.
Expansionism had devastating effects on Native American communities as it led to widespread displacement and cultural disruption. As settlers moved westward, Indigenous populations faced violent confrontations and forced removals from their ancestral lands, resulting in significant loss of life and culture. Resistance movements emerged in response to these encroachments; however, many were met with overwhelming military force. This struggle highlighted the deep conflicts between the expansionist vision of the United States and the rights of Native peoples.
