Great Depression & World War II

🇺🇸 The Great Depression & World War II

Part 1 of 7 — Economic Crisis, the New Deal & Global War

🔑 Key Concept: The AP exam tests the New Deal's transformation of the federal government's role — from limited intervention to active management of the economy and social welfare. This was the most significant expansion of federal power since the Civil War.

📖 The Great Depression (1929–1941)

Causes

The Human Cost

• Unemployment: 25% by 1933 (12–15 million workers)
• Homelessness: "Hoovervilles" — shantytowns named mockingly after President Hoover
• Dust Bowl: Severe drought + over-farming on Great Plains → massive soil erosion; Okies migrated to California
• Hoover's response: Believed in "rugged individualism" and voluntary cooperation; too slow to act; Bonus Army (1932) — WWI veterans demanded early payment of bonuses; Hoover ordered army to disperse them with tear gas

⚠️ AP Alert: The AP exam contrasts Hoover's philosophy (limited government; voluntary action) with FDR's approach (active federal intervention). This is a key ideological divide that still shapes American politics.

FDR & the New Deal

Franklin D. Roosevelt won the 1932 election in a landslide and launched the New Deal — the largest expansion of federal power in American history to that point.

Key New Deal Programs (the "Alphabet Soup")

The Three R's: Relief (immediate help), Recovery (economic restart), Reform (prevent future crises)

Criticism of the New Deal

🔑 AP Connection: The New Deal did NOT end the Depression — World War II did (through massive military spending). But the New Deal permanently transformed the role of the federal government and created the modern social safety net.

Applied Scenarios 🎯

🌪️ The Great Depression and World War II (1920–1945)

Part 6 of 7 — Problem-Solving Workshop

🔑 Key idea: Documents from 1920–1945 capture the rise of mass-consumer capitalism (1920s), its collapse (1929), the New Deal's reconstruction of federal authority (1933+), the constitutional crisis over court-packing (1937), and the moral and constitutional costs of total war (Japanese internment, atomic weapons).

HIPP for 1920s–1945 Documents

Document Bank

1. Franklin D. Roosevelt, First Inaugural Address (March 4, 1933) "So, first of all, let me assert my firm belief that the only thing we have to fear is fear itself — nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance."

• HIPP: Inaugural address delivered on March 4, 1933, three and a half years after the October 1929 stock market crash, at the very bottom of the Great Depression (~25% unemployment, banking system collapsed, ~9,000 bank failures since 1929); intended audience is the frightened American public, the banking system (FDR would close all U.S. banks the next day in the Bank Holiday and pass the Emergency Banking Act on March 9), and the Republican opposition; purpose is to restore public confidence, signal a fundamentally new federal role, and prepare the political ground for the rapid legislative program of the "Hundred Days" (March 9–June 16, 1933); POV is incoming Democratic president articulating the activist federal vision that would define the New Deal and 20th-century American liberalism.

2. Schechter Poultry Corp. v. United States (May 27, 1935, unanimous Court, "Sick Chicken case") Holding: The National Industrial Recovery Act's (NIRA, 1933) delegation of legislative power to the executive (to set "codes of fair competition" with industry input) was an unconstitutional violation of the nondelegation doctrine, AND the federal government could not regulate intrastate commerce (slaughter of chickens within New York State).

• HIPP: Unanimous Supreme Court decision (May 27, 1935, called "Black Monday" for FDR's administration) striking down the central New Deal recovery statute; intended audience is Congress, the executive, and the broader Depression-era political class; purpose of the conservative-dominated "Four Horsemen" majority (Van Devanter, McReynolds, Sutherland, Butler) plus moderate-conservative votes is to reassert pre-New Deal constitutional limits on federal economic regulation under both the nondelegation doctrine and a narrow reading of the interstate commerce clause; POV is the conservative-majority Hughes Court that would also strike down the Agricultural Adjustment Act (United States v. Butler 1936) before its 1937 reversal in the "switch in time that saved nine."

3. FDR, "Court-Packing" Fireside Chat (March 9, 1937) "We have, therefore, reached the point as a Nation where we must take action to save the Constitution from the Court and the Court from itself."

• HIPP: Fireside Chat delivered March 9, 1937, two months after FDR's landslide reelection (November 1936, 60.8% of the popular vote and 46 of 48 states) and one month after he proposed the Judicial Procedures Reform Bill (February 5, 1937), which would have allowed the president to appoint a new Supreme Court justice for every sitting justice over age 70.5 (up to 6 new justices); intended audience is the American public, congressional Democrats (many of whom were skeptical), and the conservative Court majority; purpose is to justify the court-packing plan as a necessary response to a Court that had struck down NIRA, the AAA, and other New Deal statutes; POV is FDR at the height of his electoral mandate confronting the only branch of government he could not control; the bill failed in Congress, but Justice Owen Roberts shifted vote in West Coast Hotel v. Parrish (March 29, 1937) — the famous "switch in time that saved nine."

4. Executive Order 9066 (February 19, 1942) Authorizing the Secretary of War to designate "military areas" from which "any or all persons may be excluded."

• HIPP: Executive order signed by FDR on February 19, 1942, ten weeks after the Japanese attack on Pearl Harbor (December 7, 1941); intended audience is the War Department, U.S. Army Western Defense Command, and the broader public; purpose is to authorize the forced removal of approximately 120,000 Japanese Americans (two-thirds U.S. citizens) from the West Coast to inland concentration camps; POV is wartime executive branch acting under perceived military necessity (and significant West Coast political and economic pressure); the order was upheld by the Supreme Court in Korematsu v. United States (December 1944, 6-3, Justice Black writing for the majority) and in Hirabayashi v. United States (1943); the Civil Liberties Act of 1988 issued formal apology and $20,000 reparations; Korematsu was repudiated in dicta by Chief Justice Roberts in Trump v. Hawaii (2018).

5. President Harry Truman, statement announcing the atomic bombing of Hiroshima (August 6, 1945) "Sixteen hours ago an American airplane dropped one bomb on Hiroshima, an important Japanese Army base... It is an atomic bomb. It is a harnessing of the basic power of the universe."

• HIPP: Statement issued August 6, 1945, the day the U.S. dropped the "Little Boy" atomic bomb on Hiroshima (~80,000 immediate deaths, ~140,000 by year-end), three days before the August 9 bombing of Nagasaki ("Fat Man," ~40,000 immediate, ~70,000 by year-end), and three days before the Soviet Union's August 9 declaration of war on Japan; intended audience is the American public, Imperial Japan (specifically the Japanese government), the Soviet Union, and the postwar international order; purpose is to demand Japanese surrender, demonstrate the new weapon's power, signal U.S. atomic monopoly to the Soviet Union (an early Cold War move), and justify the bombing as a means of avoiding the projected casualties of a planned U.S. invasion of the Japanese home islands (Operation Downfall, projected for late 1945 and 1946); POV is wartime executive branch; Japan accepted Allied terms on August 15, 1945 (V-J Day; formal surrender September 2, 1945).

AP SAQ Structure

For a 1920–1945 SAQ:

• A. Identify one specific 1920s development, New Deal program, OR WWII-era event
• B. Explain how it shaped American politics, economy, society, or international position
• C. Compare to a different program/event OR explain a perspective (industrial worker, sharecropper/Dust Bowl migrant, Black Southerner, Japanese American, woman war worker)

Common AP Traps

🔑 Key takeaway: 1920–1945 documents stage the formation of the modern American state — its activist economic role (New Deal), its global military role (WWII), and its constitutional accommodation of executive power (court "switch" 1937, EO 9066 1942, atomic monopoly 1945).

AP Free-Response Strategy

⚡ Sample DBQ-style prompt: "Evaluate the extent to which the New Deal (1933–1939) transformed the relationship between the federal government and the American people."

Approach:

1. Thesis (defensible claim): The New Deal (1933–1939) fundamentally transformed the federal-citizen relationship by establishing federal responsibility for economic security (Social Security 1935), labor rights (Wagner Act 1935), banking stability (FDIC 1933, Glass-Steagall 1933), securities regulation (SEC 1934), and minimum labor standards (FLSA 1938) — but the transformation was selective by race, region, and sector (farmworkers and domestic workers excluded from Social Security; FHA redlining; AAA payments to white landlords) and contested constitutionally until the 1937 "switch in time" reset the Court's relationship to the activist federal regulatory state.
2. Contextualization: Connect to Gilded Age industrialization, Progressive-era reforms (Federal Reserve, FTC, Clayton Act), and the failures of Hoover-era voluntarism (1929–32).
3. Evidence (specific): Bank Holiday and Emergency Banking Act (March 1933); CCC, AAA, TVA, NIRA, Glass-Steagall (1933); SEC (1934); Wagner Act, Social Security Act, WPA (1935); FLSA (1938); court-packing plan (1937); West Coast Hotel v. Parrish (1937); NLRB v. Jones & Laughlin (1937).
4. Analysis (sourcing): Use HIPP on at least 3 documents.
5. Complexity (the elusive 7th point): Argue that the New Deal's racial limits (Social Security exclusions; FHA redlining; segregated CCC; Southern Democratic veto on anti-lynching) and its constitutional contestation (court-packing fight) reveal it as a partial, racially-stratified, and politically negotiated social-democratic settlement — but one whose institutional legacies (Social Security, NLRB, FDIC, SEC, federal regulatory state) define 20th-century American political economy and would be expanded in the Great Society (1964–65).

🔑 Key takeaway: 1920–1945 created the modern American state (regulatory + welfare) and the modern American international position (global military + economic preeminence) — the institutional matrix within which the rest of the 20th century would unfold.
