Sep 15, 2025

Overview

This lecture covers the causes and effects of Urbanization in 19th-century America, emphasizing population growth, industrial jobs, immigration, urban problems, and the influence of political machines.

Urbanization and Population Growth

  • Urbanization is the growth of cities.
  • Between 1870 and 1900, the urban population in America grew from 10 million to 30 million.
  • By 1900, about 40% of Americans lived in urban areas.

Causes of Urbanization

  • The rise of industrial jobs in or near cities attracted workers.
  • Inventions like the Steel Plow and Mechanical Reaper increased farm productivity but required fewer workers.
  • Many unemployed former farm workers moved to cities.
  • Two major waves of immigration (1840s to early 20th century) brought millions of Europeans and Asians to American cities.

Urban Problems

  • Cities became crowded and often lacked proper sanitation, especially in poorer neighborhoods.
  • Many urban poor lived in overcrowded, poorly built tenements.
  • Crime rates were high in rapidly growing urban areas.

Political Machines and City Politics

  • Political Machines dominated city governments; Tammany Hall in New York, led by “Boss” Tweed, was the most famous.
  • Machines provided jobs and aid to poor residents in exchange for votes.
  • Political Machines were often corrupt, awarding city contracts for personal profit.
  • Kickbacks and inflated costs for public projects were common tactics.

Key Terms & Definitions
