The transition from an agrarian economy to an industrial powerhouse marked a pivotal moment in the history of the United States. By the end of the 19th century, the country was no longer defined by its rural landscapes or small-scale farms but had emerged as the epicenter of global industry and innovation. This transformation was not merely the result of technological advancements but was deeply intertwined with the economic, social, and political currents of the time. The Industrial Revolution, which had begun in Great Britain in the late 18th century, reached its zenith in America by the 1870s, setting the stage for the colossal changes that would shape the future of the nation.
