The Gilded Age describes the era following the Civil War and preceding the Progressive Era. From around 1870-1900 the United States industrialized rapidly. Factories sprung up throughout the towns and cities in the Northeast and Midwest. New railroad networks and telegraph lines connected these industries and cities with the financial centers of the nation, specifically New York City.
The Gilded Age is a complicated period. It saw the rise of monopolies and the creation of vast wealth. However, this wealth was limited to only a few families. Most Americans, including the millions of immigrants arriving annually, remained incredibly poor. The inequality of the Gilded Age prompted Progressive Reformers to enact laws which helped those poorer Americans.
New York City represented well this "tale of two cities." In 1892, 27% of the country's millionaires lived in New York, when the city only made up 2% of the country's population! Yet the vast majority of poor immigrants arriving to the country entered through New York Harbor. While many Progressive reforms got their start in the Big Apple, the city was also the center of Gilded Age opulence.
