The Roaring Twenties: Economic Shifts and the 1929 Crash

The Post-WWI Economic Shift

After World War I, global economic hegemony shifted from Great Britain to the United States, with New York emerging as the world's financial center by 1923. This era saw significant growth in production, a decrease in unemployment, and improved living standards.

Political Instability in Europe

While new democratic regimes were introduced across Europe, they were often fragile. Social tensions and upheavals spread, fueled by the fear of a communist revolution. This instability led to the rise of dictatorial regimes, most notably in 1922, when Mussolini and the Fascist Party seized power in Italy.

The Ruhr Crisis and the Dawes Plan

Tensions between Germany and France escalated when Germany failed to pay war reparations. In 1923, the French army occupied the Ruhr region, the center of German coal and steel production. The Germans responded with strikes and passive resistance.

To resolve the conflict, the U.S. launched the Dawes Plan, which established a cycle of capital flow:

• U.S. loans to Germany
• Germany pays reparations to France
• France pays war debts to the U.S.

This led to the Locarno Treaty (1925), where Germany recognized its borders and the demilitarized zone, overseen by Britain and Italy. This period, known as the Spirit of Locarno, fostered a sense of euphoria and pacifism, defining the era as the Happy Twenties.

The Origins of the 1929 Crisis

The prosperity of the 1920s eventually collapsed due to several key factors:

• Overproduction: During WWI, countries focused their economies on wartime production. When the war ended, the return to normal production levels created a massive surplus of goods.
• Speculation: The U.S. economy relied heavily on stock and real estate speculation. Banks granted loans to companies that falsified accounts to appear profitable, leading to inflated capital and rising interest rates.

The Great Crash

The crisis culminated on Black Thursday, October 24, 1929, when a massive stock sell-off caused corporate values to collapse, ruining countless investors. The consequences were severe:

• Increased unemployment and reduced consumption.
• A contraction in bank loans, hindering business expansion.
• The U.S. reduced imports, spreading the crisis to international trading partners.
• U.S. banks began repatriating capital, further destabilizing global markets.

The League of Nations attempted to address the crisis through the London Conference, but the effort failed to foster the necessary international cooperation.
