This PowerPoint presentation charts the growth of urban areas, driven in large part by an explosion in immigration, during the Gilded Age. It begins by attempting to explain why cities experienced such phenomenal growth during this time period. It talks about both push and pull factors. The poem "The New Colossus" serves as an entry point to discussing American attitudes toward immigrants in this era. It also examines the problems that massive urban growth caused for cities including water, fire, and time. The growth and persistence of tenement slums is explored in detail, largely through the photographs of Jacob Riis. It next covers attempts to reform conditions for the urban working poor through things like the Americanization and Settlement House movements. It concludes with an examination of rising nativism. It explores issues of social darwinism and machine politics, including Boss Tween and Tammany Hall in New York. This presentation is used in an Advanced Placement United States history class and is based on the first half of Chapter 25 of The American Pageant, 14th ed.
