Why did the permanent Indian fronteir fail?

Answer 1

The concept of a permanent Indian frontier failed primarily due to the continuous expansion of European settlers and the U.S. government's policies that encouraged westward migration. The fluctuating nature of treaties and conflicts with Native American tribes undermined the stability of the frontier. Additionally, economic interests, such as mining and agriculture, further pushed settlers beyond the designated boundaries, leading to increased tensions and violence. Ultimately, the frontier was rendered ineffective as a means of separating settlers from Indigenous populations.
