What document ended World War I?

The Treaty of Versailles is recognized as the document that officially ended World War I. Signed on June 28, 1919, this treaty marked the formal conclusion of hostilities between Germany and the Allied Powers. It included not only the establishment of the League of Nations, aimed at promoting international peace and cooperation, but also imposed heavy reparations and territorial losses on Germany, significantly reshaping the geopolitical landscape of Europe after the war.

The significance of the Treaty of Versailles extends beyond merely ending the conflict; it laid the groundwork for future international relations and tensions. Its harsh terms contributed to economic difficulties in Germany, which ultimately played a role in the rise of extremist political movements in the years that followed.

Other treaties, such as those referenced in the other choices, addressed different contexts or conflicts. The Treaty of Paris generally refers to various treaties that concluded different wars, including the one that ended the American Revolutionary War, while the Treaty of Ghent ended the War of 1812. The Treaty of Trianon dealt specifically with Hungary following World War I but was not the treaty that formally ended the war itself. Thus, the Treaty of Versailles stands out as the definitive document that concluded World War I.
