How did world war 1 contribute to Europe and economic weakness leading up to the Great Depression?

World War I significantly weakened European economies through extensive destruction, loss of manpower, and massive debt incurred by countries involved in the conflict. The war disrupted trade patterns and led to hyperinflation in countries like Germany, exacerbating economic instability. Additionally, the Treaty of Versailles imposed heavy reparations, further straining national economies. This fragile economic landscape, combined with the speculative practices in the 1920s, ultimately contributed to the onset of the Great Depression in 1929.
