The Great Depression
1929 Wall Street, New York, United States (and then the whole world)
In short
In the 1920s many Americans had bought shares, small parts of companies, hoping their value would keep on rising. In October 1929 the New York Stock Exchange, on Wall Street, crashed: in a few days a huge number of people lost their savings. Banks and factories closed, and in the United States in 1933 about one worker in four had no job. The crisis spread to Europe and the rest of the world.
Why it matters It taught that countries' economies are linked and pushed governments to step in more, as President Roosevelt did with the New Deal.

The story
The Roaring Twenties
In the United States, the 1920s were a time of great optimism. After the First World War the country had become the world's leading economic power. Factories turned out cars, household appliances and radios without stopping, and many families bought on credit, that is, paying a little at a time. The New York Stock Exchange, where shares in companies are bought and sold, kept rising and rising: huge numbers of people, even ordinary ones, invested in shares, convinced that prices would go on rising for ever. Some borrowed money from the banks to buy even more shares.
But beneath the surface there were problems. Many farmers were deep in debt, because the price of wheat had fallen; workers' wages were not growing as fast as company profits, so many people did not have enough money to buy everything the factories produced. Shares were worth far more than the companies really produced: it was a “bubble”, like a soap bubble, ready to burst.
The October crash
At the beginning of October 1929 share prices began to fall. On Thursday 24 October, “Black Thursday”, thousands of frightened investors tried to sell everything at once: prices plunged. Some big banks stepped in to calm the market, but on 29 October, “Black Tuesday”, more than sixteen million shares were sold in a single day, a number never seen before, and prices collapsed again. In a few weeks, many people lost all their savings.
The stock market crash alone does not explain what happened next. But it was the spark: people who had lost money stopped buying, companies sold less and laid off workers; many banks, which had lent money to people who could not pay it back, failed, and the people who had deposited their savings there never saw their money again. Fear made the crisis worse: the more frightened people were, the less they spent, and the more companies closed.
The Great Depression
Between 1929 and 1933 American industrial production fell by almost half and unemployment reached one worker in four. The cities filled with people who had no home and no job, who lived in shacks called, ironically, “Hoovervilles” after President Herbert Hoover, and queued outside soup kitchens. On the Great Plains, a terrible drought and dust storms, the “Dust Bowl”, ruined hundreds of thousands of farmers, many of whom moved to California in search of work: their story is told by John Steinbeck in the novel The Grapes of Wrath.
The crisis spread all over the world, because economies were connected: the United States stopped buying goods abroad and called in its loans from Europe. Germany, already in difficulty because of war reparations, was hit hard, with millions out of work. Italy suffered too: the Fascist government created public institutions, such as the IRI in 1933, to rescue the banks and the big companies.
The New Deal
In 1932 the Americans elected Franklin Delano Roosevelt as president, who promised “a new deal” for the people: the New Deal. The government stepped in decisively: it closed the banks temporarily to check them and restore confidence, created insurance on deposits, paid for big public works, such as dams, roads and bridges, which gave jobs to millions of unemployed people, and introduced the first pensions and unemployment benefits. Roosevelt spoke to citizens on the radio in his “fireside chats”, calmly explaining what he was doing.
The recovery was slow, and unemployment stayed high until the Second World War, when the factories began to produce weapons and work returned.
Why it happened
The Great Depression came from a combination of causes: overproduction and too much debt, a stock market swollen by speculation, banks that were poorly supervised, an unequal distribution of wealth and a fragile system of international trade after the war. When confidence disappeared, everything collapsed.
The mistakes of governments and central banks made the crisis worse: they let many banks fail, reduced the amount of money in circulation and in 1930 raised taxes on foreign goods with a law, the Smoot-Hawley Act, which reduced world trade.
What changed
The Great Depression changed the role of the state in the economy. Before, people thought the government should step in very little; afterwards, the idea was accepted that it could and should help people who lose their jobs, supervise the banks and support the economy in difficult times. The modern “welfare state” was born, with pensions, benefits and insurance. The English economist John Maynard Keynes argued that in times of crisis the state should spend more to get the economy moving again.
It also had serious political consequences: poverty and despair helped extremist movements to rise, such as Nazism in Germany, which led to the Second World War.
After the crisis a system of rules for finance was created, to avoid further crashes: checks on banks, rules for the stock exchange. When another great crisis broke out in 2008, many people asked whether the lessons of 1929 had been forgotten, and the two events were often compared.
