STAAR US History Module 2 Imperialism and World War I: a complete overview of overseas expansion, the Spanish-American War, US entry into the war, the home front, and the peace

What Module 2 actually demands

Module 2 carries the STAAR US History story from the nation's first big push overseas to the end of World War I, roughly 1890 to 1920. It explains why the United States became a world power, how it was drawn into a global war, and how that war reshaped the country at home. The dominant skills are cause and effect and reading stimulus sources (political cartoons, propaganda posters, maps, and quotations). The module reaches across all four reporting categories, with a heavy load in History and Government and Citizenship.

This guide ties together the matching dot-point pages, each with its own practice questions: American imperialism, the Spanish-American War, the United States enters World War I, the World War I home front, and the Treaty of Versailles and the League of Nations.

American imperialism

After 1890 the United States built an overseas empire for three linked reasons: economic (markets and raw materials), strategic (a strong navy needing bases, per Alfred Thayer Mahan), and ideological (spreading culture and influence). It annexed Hawaii and gained Puerto Rico, Guam, and the Philippines. Expansion sparked a sharp debate between imperialists (empire brings wealth and power) and anti-imperialists (ruling people without consent betrays self-government), a two-sided argument STAAR loves to test.

The Spanish-American War

The Spanish-American War (1898) grew out of the Cuban revolt against Spain, American economic interests, yellow journalism (sensational reporting by Hearst and Pulitzer), and the explosion of the USS Maine ("Remember the Maine"). The United States won quickly and gained Puerto Rico, Guam, and the Philippines while making Cuba a protectorate. Its significance is that a short war announced the United States as a world power with an empire reaching into the Caribbean and the Pacific.

Entering World War I

World War I began in Europe in 1914 from the M-A-I-N causes (militarism, alliances, imperialism, nationalism) and the assassination of Franz Ferdinand. The United States stayed neutral until 1917, when German unrestricted submarine warfare (the Lusitania and later American ships) and the Zimmermann Telegram (a German offer to ally with Mexico) convinced Americans of a direct threat. President Wilson asked Congress to declare war to make the world "safe for democracy."

The home front

The war demanded total mobilization: a draft, a managed war economy, war bonds, rationing, and propaganda. It opened opportunities, drawing women into the workforce and driving the Great Migration of African Americans from the rural South to northern cities (pulled by jobs, pushed by segregation). It also tested civil liberties: the Espionage and Sedition Acts punished dissent, and Schenck v. United States (1919) ruled that free speech can be limited when it poses a clear and present danger.

The peace and isolationism

Wilson's Fourteen Points envisioned a generous peace and a League of Nations, but the European Allies imposed the harsher Treaty of Versailles (1919), blaming Germany and demanding reparations. The US Senate rejected the treaty, mainly opposing the League for fear of future foreign wars without congressional consent. The United States never joined the League it inspired and returned to isolationism, leaving the postwar order weak, a condition often tied to the later rise of World War II.
