Between 1890 and 1945, the United States remade itself economically, politically, and globally. Industrial growth, overseas expansion, reform movements, two world wars, and a catastrophic depression each forced Americans to reconsider the role of government, the meaning of democracy, and the country's place in the world.
The U.S. acquired overseas territories after the Spanish-American War, debated imperialism, and launched Progressive Era reforms targeting political corruption, economic inequality, and social conditions. Key figures include Theodore Roosevelt, Woodrow Wilson, and Jane Addams. Key legislation includes the 16th, 17th, 18th, and 19th Amendments.
U.S. entry into World War I broke the tradition of noninvolvement in European affairs. The home front saw civil liberties restrictions, the Great Migration, and nativist backlash. The 1920s brought consumer culture, mass media, the Harlem Renaissance, immigration quotas, and cultural controversies like the Scopes Trial.
The Great Depression triggered the New Deal, which expanded federal power and created a lasting Democratic coalition. Interwar isolationism gave way after Pearl Harbor. World War II mobilization ended the Depression, opened new opportunities for women and minorities, and positioned the U.S. as the world's leading power by 1945.
Across Unit 7, each major crisis pushed the federal government to act more broadly. Progressive reforms regulated the economy and expanded democracy. World War I required government management of speech, labor, and production. The New Deal created a limited welfare state. World War II mobilization made the federal government the central force in American economic and social life. By 1945, the U.S. had also replaced its tradition of isolationism with permanent global engagement.
Explains the economic, social, and political context of 1890-1945, including the rural-to-urban industrial shift, Progressive Era reform impulses, and the New Deal response to the Depression.
Covers the arguments for and against overseas expansion in the 1890s, including economic, racial, and strategic justifications from imperialists and self-determination arguments from anti-imperialists.
Examines the causes and effects of the 1898 war, including U.S. acquisition of Puerto Rico, Guam, and the Philippines, the Platt Amendment, and the Philippine-American War.
Covers Progressive Era reform goals, muckraking journalism, constitutional amendments (16th-19th), conservation versus preservation, and internal divisions over race and immigration.

Period 7 opens with the United States completing its industrial transformation and beginning to project power overseas. Three key concept clusters frame the entire unit: the shift from rural to urban industrial economy, Progressive Era reform responses to that shift, and the New Deal response to the Great Depression. Understanding these frames helps you connect individual events to larger patterns of change.
In the 1890s Americans debated whether the U.S. should acquire overseas territories. Imperialists cited economic opportunity, naval strategy (Alfred Thayer Mahan), racial theories, and the 'closed frontier.' Anti-imperialists, including the Anti-Imperialist League, invoked self-determination, isolationist tradition, and democratic principles. The Spanish-American War of 1898 resolved the debate in practice: the U.S. gained Puerto Rico, Guam, and the Philippines, suppressed a Filipino independence movement, and established a protectorate over Cuba via the Platt Amendment.
| Position | Key Arguments | Representative Figures |
|---|---|---|
| Imperialist | Economic markets, naval bases, racial mission, closed frontier | Alfred Thayer Mahan, Theodore Roosevelt, William McKinley |
| Anti-Imperialist | Self-determination, democratic principles, isolationist tradition | Mark Twain, Anti-Imperialist League, Andrew Carnegie |
Progressivism was a broad reform movement from roughly 1900 to 1920 that targeted political corruption, economic inequality, and social problems created by industrialization. Muckraking journalists like Upton Sinclair exposed abuses; middle-class reformers like Jane Addams worked in settlement houses. At the federal level, Progressives pushed for regulation, democratic reforms, and moral legislation. The movement was internally divided over race, immigration, and the proper role of experts versus popular participation.
The U.S. maintained neutrality from 1914 to 1917, then entered the war citing humanitarian and democratic principles. Submarine warfare (sinking of the Lusitania), the Zimmermann Telegram, and economic ties to the Allies drove intervention. The American Expeditionary Forces helped tip the balance toward the Allies, but Wilson's Fourteen Points and the League of Nations were rejected by the Senate. At home, the war produced civil liberties restrictions, the Great Migration, nativist backlash, and a postwar Red Scare.
| Aspect | WWI Military/Diplomacy (7.5) | WWI Home Front (7.6) |
|---|---|---|
| Key cause of U.S. involvement | Submarine warfare, Zimmermann Telegram, Wilson's democratic ideals | War production demand, labor shortages |
| Major outcome | Allied victory, Senate rejects Treaty of Versailles and League of Nations | Civil liberties restrictions, Great Migration, nativist immigration quotas |
| Key legislation/policy | Fourteen Points, Treaty of Versailles | Espionage Act, Sedition Act, Emergency Quota Act |
The 1920s saw rapid technological change, a consumer boom, and deep cultural conflict. Mass production (Henry Ford's assembly line), radio, and cinema created a national consumer culture. The Harlem Renaissance produced major African American literary and artistic expression. At the same time, nativism produced immigration quotas, the Ku Klux Klan revived, Prohibition generated organized crime, and the Scopes Trial dramatized tensions between modernism and religious fundamentalism.
The stock market crash of October 1929 (Black Tuesday) triggered a decade-long depression marked by bank failures, mass unemployment, and the Dust Bowl. Herbert Hoover's limited response gave way to FDR's New Deal, which used federal power to provide relief, stimulate recovery, and reform the financial system. The New Deal did not end the Depression but created lasting regulatory agencies, the Social Security system, and a Democratic political coalition. Critics from the left (Huey Long, Father Coughlin) and right (conservative Congress, Supreme Court) challenged its scope.
After rejecting the League of Nations, the U.S. pursued a unilateral foreign policy in the 1920s that combined isolationism with selective international engagement through investment, peace treaties (Kellogg-Briand Pact), and naval agreements (Washington Naval Conference). In the 1930s, Neutrality Acts tried to keep the U.S. out of European conflicts even as fascism rose in Germany and Italy and Japan expanded in Asia. Public opposition to involvement remained strong until the Japanese attack on Pearl Harbor on December 7, 1941.
American mobilization converted the industrial economy to war production, effectively ending the Great Depression. The U.S. became the 'Arsenal of Democracy,' supplying allies and fielding millions of troops. Mobilization opened new economic opportunities for women (Rosie the Riveter) and minorities (Tuskegee Airmen, Double V Campaign), but also produced injustices including Japanese American internment under Executive Order 9066. Allied victory came through cooperation, island-hopping in the Pacific, the D-Day invasion in Europe, and ultimately the use of atomic bombs on Hiroshima and Nagasaki.
By 1945 the war-ravaged condition of Europe and Asia left the United States as the world's dominant economic and military power. Postwar settlements at Yalta and Potsdam shaped the emerging Cold War order. Topic 7.15 asks you to compare the relative significance of Period 7's major events in shaping American identity, weighing imperialism, Progressive reform, WWI, the Depression, the New Deal, and WWII against each other using evidence and reasoning.
| Event | Impact on Federal Power | Impact on U.S. Global Role |
|---|---|---|
| Spanish-American War | Limited; expanded executive war powers | Acquired overseas empire; entered Pacific and Caribbean |
| World War I | Expanded: Espionage Act, war production boards | Broke isolationism temporarily; Senate rejected League |
| New Deal | Major expansion: regulatory agencies, welfare programs | Primarily domestic; Good Neighbor Policy in hemisphere |
| World War II | Massive: full economic mobilization, internment | Emerged as dominant global superpower with atomic monopoly |

| Term | Definition |
|---|---|
| Alfred Thayer Mahan | Naval strategist whose writings argued that sea power was essential to national greatness, directly influencing U.S. naval buildup and overseas expansion in the 1890s. |
| Anti-Imperialist League | Organization founded in 1898 that opposed U.S. overseas expansion, arguing it violated democratic self-determination and the American tradition of isolationism. |
| Fourteen Points | Woodrow Wilson's 1918 peace plan emphasizing self-determination, freedom of the seas, and a League of Nations; rejected when the Senate refused to ratify the Treaty of Versailles. |
| Espionage Act of 1917 | Federal law restricting speech and actions that interfered with the war effort; used to prosecute socialists and labor activists, raising major civil liberties concerns. |
| Great Migration | Movement of hundreds of thousands of African Americans from the South to northern and western cities during and after WWI, driven by economic opportunity and escape from racial violence, though discrimination persisted in the North. |
| First Red Scare | Post-WWI fear of communist and radical influence that led to the Palmer Raids, deportations, and attacks on labor activism and immigrant communities from 1917 to 1920. |
| Harlem Renaissance | Flourishing of African American art, literature, and music centered in Harlem in the 1920s; figures like Langston Hughes, Duke Ellington, and Bessie Smith expressed Black identity and challenged racism. |
| Black Tuesday | October 29, 1929 stock market crash that triggered the Great Depression through cascading bank failures, business closures, and mass unemployment. |
| Civilian Conservation Corps (CCC) | New Deal program established in 1933 that employed young men in conservation and public works projects, providing relief while improving national parks and forests. |
| Federal Deposit Insurance Corporation (FDIC) | New Deal agency created in 1933 to insure bank deposits and restore public confidence in the banking system after widespread bank failures during the Depression. |
| Executive Order 9066 | FDR's 1942 directive authorizing the forced relocation and internment of approximately 120,000 Japanese Americans, a major wartime civil liberties violation. |
| Atomic bombs | Dropped on Hiroshima and Nagasaki in August 1945, hastening Japan's surrender and ending WWII while sparking lasting moral and strategic debates about nuclear weapons. |
| Bracero Program | Bilateral U.S.-Mexico agreement from 1942 that allowed Mexican laborers to work temporarily in the U.S. to address wartime agricultural labor shortages. |
| Double V Campaign | African American wartime movement demanding victory against fascism abroad and victory against racism at home, raising civil rights expectations that shaped postwar activism. |
The New Deal provided relief and lasting reform but did not end the Depression. Full economic recovery came from World War II mobilization and war production. The AP exam frequently tests this distinction.
Both wars restricted civil liberties and accelerated migration, but the mechanisms differ. WWI produced the Espionage Act and the First Red Scare; WWII produced Japanese American internment and the Double V Campaign. Keep the specific evidence for each war separate.
Imperialists cited racial theories, the 'civilizing mission,' naval strategy (Mahan), and the closed frontier alongside economic markets. Anti-imperialists also used racial arguments. Reducing the debate to economics alone misses the AP's emphasis on multiple causation.
Progressives disagreed sharply on race (many supported or ignored segregation), immigration restriction, and whether reform should rely on popular participation or expert management. The AP exam rewards nuance about these internal divisions.
The U.S. pursued selective international engagement through investment, the Good Neighbor Policy, and eventually Lend-Lease even before Pearl Harbor. The Neutrality Acts show the limits of involvement, but isolationism was never absolute.
APUSH frequently asks you to explain why U.S. foreign policy changed over time. For Unit 7, be ready to trace the causes of shifts from isolationism to intervention in WWI, back toward isolationism in the 1920s-30s, and then to full global engagement after Pearl Harbor. Strong responses name specific events (Zimmermann Telegram, Neutrality Acts, Lend-Lease, Pearl Harbor) and explain the reasoning behind each shift, not just the sequence.
The AP exam often asks you to compare the Progressive Era, New Deal, and wartime mobilization as moments of federal expansion. Practice identifying what each movement or crisis added to federal power, who opposed it and why, and what limits remained. Comparison tasks may also ask you to weigh the relative significance of these expansions for American identity or democratic practice.
SAQs and DBQs may ask you to place Unit 7 events in broader context. The Gilded Age (Unit 6) created the conditions Progressives responded to; the Cold War (Unit 8) grew directly from WWII's outcome. Practice writing contextualization that explains how earlier developments made Unit 7 events possible, or how Unit 7 outcomes shaped what came next, using specific evidence rather than general statements.

APUSH Unit 7 makes up 10-17% of the AP exam, making it one of the heavier-weighted periods. The unit covers American imperialism, World War I, the Great Depression, the New Deal, and World War II from 1890 to 1945. That range means you can expect a meaningful number of multiple-choice questions and at least one free-response question touching this era on exam day.
The APUSH Unit 7 progress check includes both MCQ and FRQ parts that test the full range of Period 7 content, from the Spanish-American War and World War I through the New Deal and World War II mobilization. The MCQ section presents stimulus-based questions on topics like the Progressives, 1920s cultural controversies, and the Great Depression. The FRQ section typically asks you to analyze causation, continuity and change over time, or comparison across the period. Topics most likely to appear include: - The New Deal (7.10) - World War II: Mobilization and Military (7.12, 7.13) - World War I: Home Front (7.6) - 1920s Cultural and Political Controversies (7.8) - The Great Depression (7.9) Practice with matched questions at APUSH Unit 7.
To practice APUSH Unit 7 FRQs, focus on the topics that generate the most free-response prompts: the New Deal, World War II mobilization, World War I diplomacy, and the Great Depression. Unit 7 FRQs typically appear as Long Essay Questions (LEQs) asking you to argue causation or continuity and change, or as Document-Based Questions (DBQs) pulling sources from the 1890-1945 period. A solid practice routine looks like this: 1. Pick one high-yield topic, such as the New Deal or World War II home front. 2. Write a thesis that makes a historically defensible claim. 3. Support it with at least three specific pieces of evidence. 4. Check your response against College Board scoring guidelines. You'll find practice prompts and scoring tips at APUSH Unit 7.
The best place to find APUSH Unit 7 practice questions, including multiple-choice and full practice test sets, is APUSH Unit 7. That page has MCQ practice tied to specific topics like World War II, the New Deal, and the Spanish-American War, so you can target the areas where you need the most work rather than reviewing everything at once. When doing MCQ practice for this unit, prioritize stimulus-based questions on the Great Depression, World War I home front, and 1920s cultural controversies, since those topics appear most often in the 10-17% exam weight range Unit 7 carries.
Study APUSH Unit 7 by building a clear chronological spine first: imperialism and the Spanish-American War, then World War I, then the 1920s boom and backlash, then the Great Depression and New Deal, then World War II. That narrative flow is exactly what the exam tests, so understanding how each era caused the next is more useful than memorizing isolated facts. Here's a practical study plan: 1. Read through the 15 topics at APUSH Unit 7 and flag the ones that feel unfamiliar. 2. For the New Deal, know the specific programs (CCC, SSA, FDIC) and the debates over federal power they sparked. 3. For World War II, connect mobilization on the home front to changes in civil rights expectations, since that link shows up in LEQs and DBQs. 4. Practice writing one thesis per major topic before moving to full essay practice. 5. Review your progress check results to see which topics still need work. Unit 7 carries 10-17% of the exam, so the time you put in here pays off across multiple question types.
