The white treatment of the native peoples in America is a long, bloody history that I won't even begin to go into. If you are unfamiliar, it was and still is one of the largest mass genocides in history.
Chief Joseph was the leader of the Nez Perce tribe who waged a long and ultimately fruitless campaign against the United States government. It was said that in "In his long career, Chief Joseph cannot accuse the government of the Untied States of one single act of justice." In his own words, Chief Joseph said this:
Hear me my chiefs!
Tell General Howard I know his heart. What he told me before, I have it in my heart. I am tired of fighting. Our Chiefs are killed; Looking Glass is dead, Ta Hool Hool Shute is dead. The old men are all dead. It is the young men who say yes or no. He who led on the young men is dead. It is cold, and we have no blankets; the little children are freezing to death. My people, some of them, have run away to the hills, and have no blankets, no food. No one knows where they are - perhaps freezing to death. I want to have time to look for my children, and see how many of them I can find. Maybe I shall find them among the dead. Hear me, my Chiefs! I am tired; my heart is sick and sad. From where the sun now stands I will fight no more forever.
