The Great Depression, Authoritarianism, and World War II

Global Economic Collapse: The Great Depression (1929 – ca. 1939)

• Trigger event: U.S. stock‐market crash (24–29 Oct 1929) → \text{Dow Jones loses }\approx 90\% of its value within 6 months.
• Core mechanism: Buying on margin (investors & banks paid only ~10 % cash, borrowed the rest) amplified losses.
• Banking practice: 80–90 % of some banks’ deposits invested in equities; runs emptied reserves ⇒ thousands of bank failures.
• Interconnected world markets: U.S. = largest industrial economy; crash propagated through credit lines & trade → global depression inside two years.
• Industrial spiral: demand ↓ → production ↓ → layoffs ↑ → income ↓ → demand ↓ (self-reinforcing loop).
• Worldwide unemployment estimates: 15\%\le U \le 33\% (peak nation-specific highs)
  • U.S. U_{1933}\approx 25\%
  • Minorities/immigrants: up to 50!\text{–}!70\% unemployment.
• Human face: 1937 Louisville flood photo (Margaret Bourke-White) juxtaposes poverty line vs. billboard “World’s Highest Standard of Living” → illustrates racial & class irony.

Socio-Economic Consequences in the United States

• Hunger & homelessness; environmental crises (Dust Bowl) compounded rural distress.
• Political danger: economists warned U\ge 30\% can topple governments; U.S. stability survived via robust institutions.

Franklin D. Roosevelt’s New Deal (1933 – 1939)

• Aimed at (1) Immediate relief/employment, (2) Economic recovery, (3) Structural reform.
• “Alphabet Agencies” (WPA, CCC, PWA, AAA, CWA, TVA …)
  • Works Progress Administration (WPA): at peak employed \approx 20\% of labor force; built infrastructure nationwide.
  • Agricultural Adjustment Act (AAA): price supports & acreage quotas; tied South-west irrigation projects to federal spending → birth of California agribusiness.
• Birth of U.S. welfare state: Social Security Act (1935) ⇒ national pension funded by payroll tax. 95 % of Americans ultimately receive benefits → largest federal transfer program.
• Ideological shift: from “self-made man” to acceptance of federal safety nets; conservative critique labeled policies “socialist.”

Global Responses & Protectionism

• Tariffs: Nations imposed import duties to force domestic production (e.g.
  British Conservative Party poster “Buy British or Go Jobless”).
• Short-term effect: scarcity/inflation; long-term goal: industrial self-reliance.
• Scandinavian model: deeper social-welfare spending financed via debt.
• Colonies (monoculture economies—tea, rubber, cocoa) suffered most: demand collapse; some regions U>80\%.
• Brazil famously burned millions of coffee sacks to reduce glut.

Rise of Authoritarian & Totalitarian States

Stalin’s USSR

• NEP (Lenin, 1921) ➔ limited market freedom; abolished by Stalin.
• First Five-Year Plan (1928-32): targets \Delta\text{Industrial}=+250\%, \Delta\text{Agriculture}=+150\%.
• Forced collectivization → famine; est. \ge 5\text{ million} dead in Ukraine (Holodomor) alone.
• Great Purge (1936-38): show trials; \approx 1!–!2\text{ M} executed; total Stalin deaths 40–80 M (range).

Hitler’s Germany

• Influenced by Austro-German ultranationalism, Social Darwinism, antisemitism.
• 1923 Beer Hall Putsch failed; wrote Mein Kampf in prison.
• Exploited Depression: by 1931 half of Nazi members <30 yrs.
• Enabling Act (1933) granted dictatorial power.
• Economy: “German New Deal” (autobahns, stadiums, rearmament) drove unemployment to \approx 0\% by 1938.
• Legal persecution:
  • Nuremberg Laws (1935): revoked Jewish citizenship, prohibited “Aryan–Jewish” marriage.
  • Kristallnacht (9–10 Nov 1938): ~7,500 businesses & 1,000 synagogues destroyed; 30,000 Jews to camps.
• Propaganda monopoly: state radio, news, film (Goebbels ministry); mass book-burnings 1933.

Axis Expansion & Appeasement

• Rhineland remilitarized (1936) → Anschluss of Austria (Mar 1938) → Sudetenland (Munich Pact, Sept 1938; Chamberlain’s “peace in our time”) → full Czechoslovakia (Mar 1939).
• Nazi-Soviet Non-Aggression Pact (Molotov-Ribbentrop, Aug 1939) secretly divided Poland & Baltics.
• Invasion of Poland 1 Sept 1939 → Britain & France declare war (3 Sept).

World War II in Europe (1939-45)

• Blitzkrieg: integrated tanks + motorized infantry + air cover; Poland crushed in 4 weeks.
• Western Front: Denmark, Norway, Low Countries; France fell June 1940 — Vichy regime under Marshal Pétain; small Résistance fought occupation.
• Battle of Britain (Jul-Oct 1940): RAF defeats Luftwaffe; first major German setback.
• Operation Barbarossa (22 Jun 1941): largest land invasion ever; stalled by Soviet winter & over-extension.
• Total War economy: By 1943 U.S. output > rest of world combined; Soviet manpower \approx 20\text{ M} under arms.
• Final collapse: Allies enter Germany April 1945; Hitler suicide 30 Apr; unconditional surrender 7–8 May (V-E Day).

The Holocaust

• Evolution from forced emigration → ghettos → “Final Solution” (Wannsee, Jan 1942).
• Network of camps: Auschwitz-Birkenau, Treblinka, Sobibor … plus mobile killing units (Einsatzgruppen) & gas vans.
• Victims: \approx 6\text{ M} Jews, \approx 6\text{ M} other targets (Slavs, Roma, disabled, LGBT+, POWs). Half of total WWII death toll.

Japan’s Road to War

• Manchuria seized 1931; full invasion of China 1937 (Marco Polo Bridge) → “Three Alls” policy: Kill all, Burn all, Loot all.
• Joined Axis (Tripartite Pact, Sept 1940).
• U.S. oil embargo 1940 (≈ 85 % of Japanese supply) ⇒ strategic deadline ≤ 18 months.
• Pearl Harbor 7 Dec 1941: 2,400 Americans killed; ~50 % Pacific Fleet damaged, but carriers absent.

War in the Pacific

• Early Japanese gains: Philippines, Malaya, Dutch East Indies; atrocities incl. Bataan Death March, “comfort women.”
• Turning points:
  • Battle of Midway (4-7 Jun 1942): U.S. sinks 4 Japanese carriers; strategic initiative shifts.
  • Island-hopping (Guadalcanal → Saipan → Iwo Jima → Okinawa). High casualties: Iwo Jima \approx 26,000 U.S., \approx 21,000 Japanese.
  • Battle of Leyte Gulf (Oct 1944): largest naval battle; Japanese navy neutralized.
• Soviet entry vs. Japan (Aug 1945) captured Manchuria & Korea.
• Manhattan Project (cost \$2\text{ B}, 200,000 personnel). Trinity test 16 Jul 1945.
• Atomic bombs:
  • Hiroshima 6 Aug 1945 → \approx 140,000 deaths (by end ’45)
  • Nagasaki 9 Aug 1945 → \approx 80,000 deaths
• Japan’s surrender 15 Aug (formal 2 Sept) 1945; motives include bomb shock and fear of Soviet invasion.

Ethical, Philosophical, & Practical Implications

• Depression revealed fragility of laissez-faire capitalism → rise of welfare economics, Keynesian deficit spending.
• Totalitarian systems exploited crisis: promises of stability & identity trumped civil liberties.
• Propaganda, censorship, and “othering” illustrate how mass psychology can enable genocide.
• Nuclear weapons introduced existential risk; less-loss rationale vs. civilian immunity debates still frame just‐war theory.

Remember: Economic shocks can upend political orders; vigilance against scapegoating, propaganda, and erosions of democratic norms remains a timeless lesson.
