The document summarizes the Trail of Tears, which was the forced relocation of Native American tribes from the Southeast U.S. to lands west of the Mississippi River in the 1830s. It discusses the Cherokee, Creek, Choctaw, Chickasaw, and Seminole tribes being removed from their homelands in Tennessee, Alabama, North Carolina, and Georgia to Indian Territory due to the U.S. government's policy of Indian removal. The removal process was enabled by the passage of the Indian Removal Act and resulted in thousands of Native American deaths during the forced marches west.
