GILDED AGE. Named after an 1873 social satire by Mark Twain and Charles Dudley Warner, the Gilded Age encompasses the years from the 1870s to 1900. Scholars tend to see the legacies of the Civil War and Reconstruction as important contributors to the transformations that took place in the last three decades of the nineteenth century.

The Gilded Age was an era in history following the American Civil War (1861–65) and Reconstruction (1866–77), the period after the American Civil War during which the Southern states were reorganized and brought back into the Union). Spanning approximately 1877 to 1900, it was a time of economic expansion and development, due primarily to the Industrial Revolution. The United States transformed itself from an agrarian (agricultural)-based economy to one rooted in industry and business. Benson, Sonia, et al. "Gilded Age."
