Final answer:
After the Civil War, Native Americans were confined to reservations and became dependent on the Bureau of Indian Affairs. Small farms struggled while large farms succeeded through economies of scale. The lands used for raising animals and crops were mostly abandoned or overtaken by White Americans and European immigrants.
Step-by-step explanation:
After the Civil War, Native Americans were displaced and confined to reservations, which were usually poor in terms of farming or raising livestock. As a result, Native Americans became dependent on the Bureau of Indian Affairs for support and had to adopt Christianity and abandon their traditional cultures in boarding schools.
Additionally, as the railroad expanded and better farm equipment became available, large farms succeeded through economies of scale. Small farms struggled, leading to rising discontent among farmers.
The lands that had been used for raising animals and crops were not taken over by Native American tribes, redistributed to Mexican landowners, or converted to mining operations. Rather, they were mostly abandoned or overtaken by White Americans and European immigrants.
