The treaty that officially ended the First World War was the Treaty of Versailles, signed on June 28, 1919. The treaty was negotiated among the Allies and imposed significant penalties on Germany, including territorial losses, military restrictions, and reparations. It aimed to establish a framework for lasting peace but created significant discontent in Germany, which felt humiliated by the conditions. The treaty's punitive measures and failure to address underlying issues contributed to political instability in Germany, eventually leading to the rise of Adolf Hitler and the outbreak of World War II. The treaty's legacy remains a subject of extensive debate among historians.
