The Great Depression

A severe worldwide economic downturn that began with the U.S. stock market crash of October 1929 and lasted through the late 1930s, marked by mass unemployment, bank failures, and sharp drops in output and prices. In the United States it is generally considered to have ended with the industrial mobilization for World War II.

In plain English
When the economy fell off a cliff.

The worst economic collapse in modern U.S. history, when banks failed, businesses closed, and roughly one in four workers lost their jobs.

Simple example
At its 1933 peak, U.S. unemployment reached about 25%, and thousands of banks had failed, wiping out the savings of millions of Americans.
Why it matters
What the term actually changes.
Context for the New Deal

The scale of the Depression is the baseline against which the New Deal's success or failure is usually measured.

Reshaped expectations

The crisis changed what Americans expected government to do in a downturn, paving the way for safety-net programs and financial regulation.

Lessons for today

Policymakers and economists still study the Depression to guide responses to recessions, banking panics, and financial crises.

How it works
The mechanics, in practice.
Cascading bank failures

Stock losses, bank runs, and tight monetary policy caused thousands of banks to collapse, shrinking the money supply and credit available to businesses.

Collapse in demand

Falling wages and rising unemployment cut consumer spending, which led to further layoffs, factory closures, and deflation in a self-reinforcing cycle.

Global spread

Trade barriers like the Smoot-Hawley Tariff and the gold standard transmitted the downturn worldwide, deepening and prolonging the slump.
