What you'll learn

Period 6 (1865–1898) — rapid industrialization and its social conflicts (~10–17%).

Industrialization & the Gilded Age

Big business and trusts (Carnegie, Rockefeller); laissez-faire ideology and Social Darwinism; vast wealth alongside poverty and corruption.

Labor

Unions (Knights of Labor, AFL) and strikes (Haymarket, Homestead, Pullman) responded to harsh conditions; usually defeated in this era.

Immigration & urbanization

New immigration (Southern/Eastern Europe, Asia) filled cities and factories; nativism rose (Chinese Exclusion Act, 1882). Political machines ran cities.

The West

Railroads, mining, and farming expanded settlement; Native nations were forced onto reservations (Dawes Act, 1887); the 'closing' of the frontier.

Farmers & Populism

Falling prices and debt spurred the Populist movement demanding reforms (regulation, free silver).

Key themes

  • Industrial capitalism reshaping society and the West.
  • Responses to inequality (labor, Populism).

Exam tips

  • Link industrialization to labor, immigration, and Western change.

Common mistakes

  • Ignoring the period's labor and farmer resistance.
