Answer: Railroad
Native American tribes had already been struggling for decades before the construction of a railroad began to be planned. However, the railroad was a catastrophic event for the Natives' way of life. The railroad forever altered the landscape of their traditional land, as well as caused the disappearance of wild game, such as bison.
