Indian relocation into the West (Oklahoma today)
What was it?
A forced relocation of Native Americans consisting of 5 nations of Indians from the Southeast who were forced westward. This was the result of the Indian Removal Act of 1830 which Andrew Jackson proposed and supported.
It was infamously known as a very disturbing treatment of Indians because many died during the trip; an estimated 1/3 of the Indians died during the relocation due to exposure, disease and starvation. They finally relocated into the Indian Territory, modern-day Oklahoma.
The five nations (Cherokee, Chickasaw, Choctaw, Creek, and Seminole) were known as the "Five Civilized Tribes" by whites because of their apparent acceptance of many parts of Anglo-American culture. Look how far that got the poor guys.
