Gilded Age

The Gilded Age spans roughly the end of Reconstruction to the turn of the twentieth century. Mark Twain and Charles Dudley Warner coined the label in their 1873 novel The Gilded Age, contrasting a gold surface with the cheaper metal underneath: dazzling industrial growth and fortunes on display, alongside poverty, unsafe workplaces, and corrupt politics.

Industrial expansion drove the era. Railroads knit a national market together, steel and oil scaled into vast enterprises under men such as Andrew Carnegie and John D. Rockefeller, and new corporate forms — trusts, holding companies, and horizontal and vertical integration — concentrated control of whole industries. Millions of immigrants from southern and eastern Europe, along with migrants from American farms, filled the factories and swelled cities. Defenders invoked Social Darwinism and the "gospel of wealth"; critics called the industrialists robber barons.

Politics and labor defined the era's conflicts. National elections were extremely close, party machines like New York's Tammany Hall traded services for votes, and patronage dominated federal jobs until the Pendleton Civil Service Act of 1883 introduced merit exams. Workers organized through the Knights of Labor and the American Federation of Labor, and confrontations including the Great Railroad Strike of 1877, the Haymarket affair of 1886, the Homestead strike of 1892, and the Pullman strike of 1894 often ended with federal or state force. Farmers pressed their own grievances through the Grange and the Populist movement, demanding railroad regulation and currency expansion.
