Answer:
Migrated voluntarily
Were forced to move
Step-by-step explanation:
Before the Indian Removal Act, the Plains Native American tribes moved freely and migrated from one place to another in search of food and shelter. They hunted animals for food and trade with other tribes. Some of the tribes in the Plains include Blackfoot, Cheyenne, Comanche, Crow, Lakota, Plains Apache (or Kiowa Apache), etc.
After the Indian Removal Act, the Native Americans land was taken away for the white settlers for settlement. The act required the relocation of the Native Indians. The resettlement of Native Indians created the Second Great Removal.
