The Economy in the
Interwar Period
Explore how global economic forces shaped the world between 1919 and 1939: from postwar recovery and the Roaring Twenties to the devastating Great Depression and the rise of new economic ideologies.
What Was the Interwar Economy?

After World War I devastated European economies, nations struggled with war debts, inflation, and the challenge of converting wartime production back to peacetime industry. This era witnessed both unprecedented prosperity and catastrophic collapse.
