New York: The Power and the People (1898–1918)

As the city starts building the skyscrapers that would make its skyline iconic, 10 million immigrants arrive in New York. The immigrants lived in frequently squalid conditions and worked in the city's most undesirable jobs. In 1911, when 146 female Jewish and Italian immigrants died in the Triangle Shirtwaist Factory fire, the city was largely unified in the successful demand for legislation on new factory safety reforms and labor laws.
