The Gilded Age: Robber Barons, Reformers, and the Making of Modern America

The era of steel, strikes, and staggering fortunes — how the United States industrialized, and who paid for it.

Mark Twain gave the era its name, and he did not mean it as a compliment. A gilded thing is gold only on the surface; underneath it is something cheaper. In the decades after Reconstruction, the United States became the richest industrial power on earth — and also a country of company towns, child labor, and tenements, where a handful of men controlled fortunes larger than the federal budget. The same years built the steel mills, the railroads, and the electrified cities that made modern America, and exposed an inequality so raw it produced a generation of strikes, third parties, and reformers determined to tame it.

This guide works through that contradiction. It begins with the era and the men who dominated it — the industrialists their admirers called captains and their critics called robber barons — then turns to the inventions and spectacles that announced the new economy, the violent rise of organized labor, and the political revolt and reform that the Gilded Age's excesses finally provoked. Each entry links to a full account. The throughline is a single question the country is still arguing over: what does a democracy owe the people left behind by its own prosperity?

The reform impulse the Gilded Age set loose came of age in the decades that followed — the Progressive Era and the trust-busting that broke the empires built here. For the workers' side of the story, read the guide to the American labor movement; for the fortunes and panics, a history of American financial crises.
