This is the story of the financial cataclysm that started with the Wall Street stock market crash of 1929, and set in motion a series of economic, political and social events that affected many millions of people in America, Britain, Europe and Australia.

The Crash rolled across the world like a tidal wave, toppling governments, spreading the wave of dictatorships in Italy and Germany, infecting entire industries and plunging millions into unemployment and poverty. By the time it began to lift in 1935, the lives of people in scores of countries had changed forever.
