The building of the Central Pacific and Union Pacific railroads harmed and displaced many Native American tribes–including the Sioux, Arapaho, Cheyenne, Shoshone, and Paiute, to name a few–through altering natural resources or by the taking of native lands. Predominantly, in an effort to defend their independence and their way of life, Native Americans resisted the railroad’s construction. There were, however, tribes that worked on or offered support for its construction. During the 150th Anniversary of the Transcontinental Railroad (1869-2019), Spike150 acknowledges the suffering of those Native Americans displaced in the building of this railroad.
