The "Gilded Age" term came into use in the 1920s and 1930s and was derived from writer Mark Twain's and Charles Dudley Warner's 1873 novel "", which satirized an era of serious social problems masked by a thin gold gilding. The early half of the Gilded Age roughly coincided with the mid-Victorian era in Britain and the Belle Époque in France. Its beginning, in the years after the American Civil War, overlaps the Reconstruction Era (which ended in 1877). It was followed in the 1890s by the Progressive Era.
