Which period was closely related to the Gilded Age?

The Gilded Age, which spanned from the 1870s to about 1900, is closely related to the Progressive Era, which followed it. The Progressive Era, from the 1890s to the 1920s, emerged as a response to the social and economic issues stemming from the rapid industrialization and inequality characteristic of the Gilded Age. During this time, reformers sought to address problems such as corruption, labor rights, and women's suffrage, aiming for a more equitable society.
