The depth of hostility felt by many white Americans toward the Indians The killing of a village of peaceful Indians for no other cause than hatred and xenophobia undoubtedly contributed to the high level of hostility toward Indians.
The Sand Creek Massacre in 1864 is a prime illustration of the animosity white men had toward Native Americans. When a cavalry came into a "camp of friendly Indians," they engaged in battle despite their best efforts to avoid it.

Hatred was the prime reason for hostility towards Indians.
