The forced relocation of Native American tribes in the 19th century was a dark chapter in U.S. history. Driven by westward expansion and the ideology of Manifest Destiny, the government implemented policies like the Indian Removal Act to displace tribes from their ancestral lands. The reservation system confined Native Americans to designated areas, disrupting their traditional ways of life. This period saw widespread cultural suppression, loss of land and resources, and devastating events like the Trail of Tears, which claimed thousands of lives during forced marches to Indian Territory.
