Georgia Milestones US History Module 4 Industrialization, Progressivism, and Imperialism: a complete overview of big business, immigration, the Progressive Era, woman suffrage, imperialism, and World War I

What Module 4 actually demands

Module 4 is one of the most heavily tested stretches of the course: industrialization, reform, and imperialism, GSE standards SSUSH11 to SSUSH15, roughly 1877 to 1920. It explains how the United States became an industrial giant, what that growth cost ordinary people, how reformers responded, and how the nation stepped onto the world stage through empire and World War I. The dominant skills are reading political cartoons and charts, cause and effect, and matching reforms, amendments, and laws to the problems they addressed. SSUSH11 to SSUSH13 sit in Domain 3; SSUSH14 and SSUSH15 begin Domain 4.

This guide ties together the matching dot-point pages, each with its own practice questions: industrialization and big business, immigration and urbanization, the Progressive Era, women's suffrage and reform, American imperialism and the Spanish-American War, and World War I.

Industrialization and big business

New technology (the Bessemer process, electricity) and the railroads powered rapid growth in a free enterprise system. Andrew Carnegie dominated steel through vertical integration and John D. Rockefeller dominated oil through horizontal integration and the trust, creating near-monopolies. These men were praised as "captains of industry" and condemned as "robber barons." The first federal response was the Sherman Antitrust Act (1890).

Immigration and urbanization

A wave of new immigrants from southern and eastern Europe replaced the earlier old immigration. Push and pull factors drove the movement, and most settled in cities, crowding into tenements, fueling nativism (the Chinese Exclusion Act), and relying on political machines such as Tammany Hall, which traded services for votes.

Progressive reform and woman suffrage

The Progressive movement (about 1900 to 1920) answered the Gilded Age. Muckrakers such as Upton Sinclair (The Jungle) exposed abuses. Theodore Roosevelt pursued trust-busting and the Pure Food and Drug Act; Woodrow Wilson added antitrust law and the Federal Reserve. Four amendments expanded democracy (Sixteenth income tax, Seventeenth senators, Eighteenth Prohibition, Nineteenth suffrage). The woman suffrage movement, led by Susan B. Anthony and Carrie Chapman Catt, won the Nineteenth Amendment (1920), and the NAACP (1909) began the legal fight for civil rights.

Imperialism and World War I

The US became a world power through imperialism: yellow journalism and the USS Maine helped spark the Spanish-American War (1898), after which the US gained Puerto Rico, Guam, and the Philippines and built the Panama Canal. Then World War I: German submarine warfare and the Zimmermann Telegram brought the US in by 1917, the Great Migration moved African Americans north, and the Senate's rejection of the Treaty of Versailles kept the US out of the League of Nations.
