The Gilded Age refers to a period in American history from the 1870s to the early 1900s, characterized by rapid economic growth and industrialization. This era saw the rise of major industries, such as steel and railroads, and significant figures like Andrew Carnegie and John D. Rockefeller became prominent. However, it was also marked by stark social inequalities and political corruption. During the Gilded Age, many immigrants arrived in the United States, seeking better opportunities. Urbanization increased as people moved to cities for jobs, leading to overcrowded living conditions. Labor movements emerged in response to poor working conditions, advocating for workers' rights and fair wages.
