1920s1930sera

The 1920s–1930s era, commonly called the interwar period, spanned roughly from 1920 to 1939, the years between World War I and World War II. It was marked by social and political upheaval, economic volatility, and rapid cultural change as nations rebuilt, redefined borders, and restructured international relations following the Great War.

In the 1920s, many economies experienced growth and modernization. The period, often called the Roaring Twenties or the Jazz Age, featured rising urbanization, mass production, and expanding consumer culture. Advances in electricity, automobiles, radio, aviation, and household appliances transformed daily life. Social change accompanied economic transformation: women gained suffrage in several countries, Prohibition shaped domestic life in the United States, and cultural movements such as jazz, cinema, and the Harlem Renaissance flourished.

Politically, the era saw a mix of liberal democracies, communism in some regions, and the emergence of authoritarian movements. The aftermath of the war contributed to political instability in parts of Europe and Asia. Fascism rose in Italy, militarist regimes gained influence in Japan, and the Nazi Party ascended to power in Germany in 1933. International cooperation included the League of Nations, the Locarno Treaties (1925), and the Kellogg-Briand Pact (1928), though effectiveness varied as economic and nationalist forces grew.

Economic life was volatile. The 1929 stock market crash triggered the Great Depression, with widespread unemployment and deflation. Responses varied, from New Deal policies in the United States to protectionist measures like the Smoot-Hawley Tariff Act of 1930 elsewhere, shaping economic policy for years to come.

The era ended with rising militarism and expansionism on the eve of World War II, influencing political ideology, economic policy, and cultural life for decades.
