The Trail of Tears commonly refers to a series of forced relocations of Native American nations in the United States following the Indian Removal Act of 1830. The removal included members of the Cherokee, Muscogee, Seminole, Chickasaw, and Choctaw nations, who chose not to assimilate with American society, from their ancestral homelands in the southeastern U.S. to an area west of the Mississippi River that had been designated as Indian Territory. Native Americans who chose to stay and assimilate were allowed to become citizens in their states and of the U.S. The phrase "Trail of Tears" originated from a description of the removal of the Choctaw Nation in 1831.[2]
