What was one outcome of the westward expansion for Native American tribes?

One of the significant outcomes of westward expansion for Native American tribes was the reduction or destruction of their tribal lands. As settlers moved westward in search of new opportunities, many Native American tribes were forcibly removed from their ancestral lands through treaties that were often unfairly negotiated or outright ignored. This led to a series of conflicts and battles, as tribes fought to defend their territories. The establishment of reservations further constrained their lands, significantly altering their traditional way of life and disrupting their social structures. The loss of land had lasting effects on the tribes' ability to sustain their cultures and economies, leading to a legacy of struggle that is still felt today.
