Over the course of more than four centuries from the 1490s into the 1900s, Europeans and white Americans "engaged in an unbroken string of genocide campaigns against the native peoples of the Americas."[48] The indigenous peoples of the Americas have experienced massacres, torture, terror, sexual abuse, systematic military occupations, removals of Indigenous peoples from their ancestral territories, forced removal of Native American children to military-like boarding schools, allotment, and a policy of termination.[49]
