“[The Cherokee] look to our government for protection; rely upon its kindness and its power; appeal to it for relief to their wants; and address the President as their Great Father. They and their country are considered by foreign nations, as well as by ourselves, as being so completely under the sovereignty and dominion of the United States that any attempt to acquire their lands, or to form a political connexion with them, would be considered by all as an invasion of our territory and an act of hostility.” - John Marshall
