What brought the US into conflict with native Americans n the 1800s?

The US conflict with Native Americans in the 1800s was primarily driven by westward expansion and the desire for land. As settlers moved into territories inhabited by Indigenous peoples, the government implemented policies like the Indian Removal Act of 1830, which forcibly displaced tribes from their ancestral lands. This often led to violent confrontations, broken treaties, and the loss of traditional ways of life for many Native American communities. Economic interests, particularly in agriculture and resource exploitation, further fueled tensions and conflicts during this period.
