The Gilded Age explores one of the most transformative and contradictory eras in American history. After the Civil War, the United States rapidly became an industrial powerhouse, driven by railroads, steel, oil, electricity, mass immigration, and explosive urban growth. This book examines the rise of figures such as Andrew Carnegie, John D. Rockefeller, and Thomas Edison, while also revealing the human cost of progress: overcrowded tenements, poverty, labor exploitation, political corruption, and violent struggles for workers' rights. From Ellis Island to the Homestead and Pullman Strikes, the book presents the Gilded Age as a period of dazzling innovation and wealth built upon deep inequality, social conflict, and urgent demands for reform.
