      "editorialNote": "This article challenges the the typical periodizations of the \"Gilded Age\" and the \"Progressive Era.\" These two periods are typically placed end-to-end, from the late 1870s-mid 1890s (the Gilded Age), and the mid-1890s to 1920 (Progressive Era). Edwards writes that the Gilded Age is typically described by historians as an age of corruption, disenfranchisement, and general malaise, while the Progressive Era is described as a era of reform, innovation, and growth. Seeking to complicate this narrative, Edwards speculates about an alternative periodization that highlights continuities in the time between the end of Reconstruction and 1920.",
