Westward expansion and industrial growth transformed the United States between 1865 and 1877. Railroads and settlers moved further west, disrupting Native American lands and leading to violence. At the same time, industrialization grew rapidly as big businesses rose and cities swelled with immigrant workers. As the economy industrialized, labor movements emerged to fight for workers' rights, though racism hampered their efforts. All of this change culminated in the Great Uprising of 1877, as workers renewed demands for economic and political power.
