What this topic is asking
Framework Key Idea 10.7 opens the interwar period with the Great Depression, the worldwide economic collapse of the 1930s. It asks you to explain its causes, how it spread through an interconnected world economy, its effects (mass unemployment and hardship), and crucially how it created conditions for political extremism, the rise of the totalitarian regimes covered in the next topic. This connects the enduring issues of scarcity, economic systems, and power.
What the Great Depression was
Causes and global spread
The effects
The human cost was enormous. Unemployment soared, in some countries to a quarter or more of the workforce. Banks and businesses failed, savings were wiped out, world trade shrank, and millions fell into poverty. Families lost homes and faced hunger. The crisis discredited the idea that economies would simply fix themselves, and it shook public confidence in existing governments.
Why the Depression mattered politically
The most important point for the exam is the political effect. As the Depression dragged on and democratic governments seemed unable to end it, desperate people became willing to follow leaders who promised jobs, order, and national greatness, even at the cost of freedom. This is exactly the opening that Adolf Hitler and the Nazis exploited in Germany, and it strengthened authoritarian movements elsewhere. The Great Depression is therefore a key cause of the rise of totalitarianism and, ultimately, of World War II.
Try this
Q1. In which country did the Great Depression begin, and with what event? [Recall]
- Cue. The United States, with the Wall Street stock-market crash of 1929.
Q2. Explain why the Great Depression became a worldwide crisis. [Short explanation]
- Cue. The global economy was interconnected through trade, loans, and investment, so the collapse of the major American economy spread to other nations, raising unemployment and failures everywhere.

Regents GHG II (stimulus, 2023)1 marksA graph shows unemployment rising sharply in the United States, Germany, and Britain in the early 1930s. This worldwide pattern best shows that (1) economies were isolated from one another; (2) the world economy was interconnected, so a collapse in one country spread to others; (3) only Germany was affected; (4) the Depression had no political effects.Show worked answer →
A stimulus-based multiple-choice item assessing economics and interconnectedness (Practices E and D).
The correct answer is (2). Because the world economy was interconnected through trade, loans, and investment, the economic collapse that began in the United States spread quickly to other industrial nations, raising unemployment everywhere.
Why the others are wrong: (1) the shared pattern shows interconnection, not isolation; (3) the graph shows several countries; (4) the Depression had major political effects.
Markers reward identifying interconnectedness as why the Depression was global.
Regents GHG II (CRQ cause-effect, 2024)2 marksDocument 1 describes mass unemployment, bank failures, and falling trade during the Great Depression. Based on this document and your knowledge of social studies, explain one way the Great Depression contributed to the rise of totalitarian governments.Show worked answer →
A 2-point Cause-and-Effect CRQ (Practice B).
A complete answer explains the link: the Great Depression caused mass unemployment, poverty, and despair, and people lost faith that their existing democratic governments could fix the crisis. This made many willing to support extremist leaders, such as Hitler in Germany, who promised jobs, order, and national revival, so the economic crisis opened the door to totalitarian rule.
Markers reward connecting economic hardship and loss of faith in government to support for totalitarian leaders.
