Final answer:
Andrew Jackson's presidency affected Native Americans through the passing of the Indian Removal Act, which resulted in forced displacement of tribes.
Step-by-step explanation:
Andrew Jackson's presidency had a significant impact on Native Americans. He championed the idea of opening lands for white settlement and moving Native Americans beyond the boundaries of what was considered 'American civilization.' This led to the passing of the 1830 Indian Removal Act and the subsequent displacement of tribes such as the Creek, Choctaw, Chickasaw, Seminole, and Cherokee. This policy of ethnic cleansing and forced removal became one of the defining characteristics of the Age of Jackson.
