TO HIRE WITHOUT DISCRIMINATORY
Answer: Long before the “Trail of Tears” occurred, Native Americans were forcibly removed from their land in the name of conquest and American Manifest Destiny, or the belief that white settlers had the right to expand and occupy all territory in the Western hemisphere. This belief of conquest was ingrained in American culture, rearing its ugly head time and time again in American history. But the Trail of Tears was one of the most jarring incidents of Native American genocide, and not only left thousands of Native Americans dead, but destroyed vibrant culture.

They would have chosen the Indian-Americans (that should be referred to as Native Americans), but because of the sicknesses, that did not happen.
