Answer:The conflict between White settlers and Indigenous people occurred after the US government broke promises and Indigenous people refused to sign a treaty. These actions led to a breakdown in trust and sparked tensions between the two groups. When the US government made promises to Indigenous people, such as protecting their lands and preserving their way of life, it created expectations and hopes for a peaceful coexistence. However, when these promises were broken, it caused anger and frustration among the Indigenous communities. This breach of trust resulted in increased resistance and refusal to sign treaties that would further diminish their rights and lands. On the other hand, settlers also played a role in the conflict by refusing to sign treaties. These treaties were often proposed as a means to acquire Indigenous lands and resources, which the settlers desired for their own expansion and economic gain. The refusal of settlers to sign these treaties further fueled the tensions between the two groups. Overall, the conflict between White settlers and Indigenous people was a result of broken promises by the US government and the refusal of both parties to sign treaties. These actions set the stage for a long and troubled history between these groups, marked by violence, displacement, and the erosion of Indigenous rights and cultures.
