A key outcome of the Treaty of Versailles, which ended World War I in 1919, was the imposition of heavy reparations and territorial losses on Germany. The treaty aimed to prevent future conflicts by significantly weakening Germany's military capabilities and redrawing European borders. The League of Nations was established as part of the treaty to promote diplomatic dialogue and prevent future wars. However, the treaty's harsh terms fostered resentment in Germany, contributing to economic hardship and political unrest, which ultimately played a significant role in the rise of Adolf Hitler and the onset of World War II.
