What problems did the expansion of settlements into the West cause for First Nations people?

The expansion of settlements into the West led to significant displacement of First Nations people, disrupting their traditional ways of life and access to ancestral lands. This encroachment often resulted in violent conflicts and broken treaties, as settlers and the government sought to assert control over resources and territory. Additionally, the introduction of new diseases and the depletion of Natural Resources further threatened the survival of many Indigenous communities, exacerbating their struggles for autonomy and cultural preservation.
