📖 Setting the Scene

On October 29, 1929 — "Black Tuesday" — the American dream turned into a nightmare. Share prices on Wall Street collapsed. Fortunes were wiped out in hours. But here's the crucial point examiners want you to understand: the Crash was the TRIGGER, not the CAUSE. The American economy was already sick — built on debt, overproduction, and extreme inequality. The Crash just exposed these weaknesses. Within three years, 25% of Americans were unemployed, banks had failed, and families were living in cardboard shacks called "Hoovervilles."

🧠 Memory Aid: OSIAS — The 5 Causes of the Depression

Remember the underlying causes with OSIAS:

  • O — Overproduction (factories made more than people could buy)
  • S — Speculation (millions borrowed to buy shares on the stock market)
  • I — Inequality (60% below poverty line; most couldn't sustain consumer demand)
  • A — Agriculture in crisis (farmers struggling since early 1920s; 6 million left land)
  • S — Spending on credit (60% of cars, 80% of radios bought on hire purchase)

Then add the TRIGGER: Wall Street Crash — Black Thursday (24 Oct 1929) and Black Tuesday (29 Oct 1929) — $30 billion lost.

Key numbers to know:

  • 25% — unemployment by 1933 (1 in 4 workers)
  • 5,000 — banks that failed by 1932
  • $30 billion — share value wiped out in Crash
  • 60% — proportion of American families below poverty line
  • 60% — proportion of cars bought on credit
