What Module 4 actually demands
Module 4 is the birth of modern America: the country industrializes, fills with immigrants, reforms itself in the Progressive Era, becomes an overseas empire, and enters World War I as a world power. It straddles two reporting categories, the industrial and Progressive content in Reporting Category 2 (1865 to 1914) and imperialism and the war in Reporting Category 3 (1914 to 1945). The Enduring Issues are power, inequality, innovation, and interconnectedness.
This guide ties together the matching dot-point pages, each with its own worked questions: industrialization and the Gilded Age, immigration and urbanization, the Progressive Era, American imperialism and the Spanish-American War, World War I and American involvement, and the home front and the peace.
Industrialization (VUS.8)
Abundant resources, new technologies (cheap steel, electricity), railroads, immigrant labor, and a pro-business government powered rapid industrial growth. Carnegie (steel) and Rockefeller (oil) built monopolies through trusts. Workers, facing low wages and dangerous conditions, formed labor unions (the AFL) and used strikes. The Sherman Antitrust Act (1890) began federal regulation.
Immigration and cities (VUS.8)
The "new immigrants" from southern and eastern Europe (and Asia) poured through Ellis Island into crowded cities and tenements. They faced poverty, language barriers, and nativism (the Chinese Exclusion Act). Reformers responded with settlement houses (Hull House).
The Progressive Era (VUS.8)
Muckrakers (Sinclair, Tarbell) exposed abuses. Progressives won trust-busting and consumer protection (1906 food and drug laws), expanded democracy (initiative, referendum, recall), and added four amendments: 16th (income tax), 17th (direct senators), 18th (Prohibition), 19th (woman suffrage). It ignored racial injustice.
Imperialism (VUS.9)
The United States became a world power: the Spanish-American War (1898) brought Puerto Rico, Guam, and the Philippines; Hawaii was annexed; and the Open Door and Panama Canal extended American reach.
World War I (VUS.9)
The war's causes were M-A-I-N. The United States entered in 1917 after submarine warfare (the Lusitania) and the Zimmermann Telegram; fresh troops helped win the war. At home, propaganda, the Espionage and Sedition Acts (Schenck), and the Great Migration reshaped society. The peace, Wilson's Fourteen Points and the League of Nations, foundered when the Senate rejected the Treaty of Versailles.
