Answer
1. Indian removal act
2. Treaty of fort Jackson
3. Treaty of Guadalupe Hidalgo
Step-by-step explanation:
The Indian Removal Act forcibly removed American Indians from their homelands. With the Treaty of Fort Jackson, the Creek Nation and other tribes lost almost two million acres of land. The Treaty of Guadalupe Hidalgo meant that Mexicans living on the lands given to the United States were displaced, forced out, or treated poorly by Americans.
