Which treaty officially ended World War I?

The Treaty of Versailles is recognized as the treaty that officially ended World War I, concluding hostilities between the Allied Powers and Germany. Signed on June 28, 1919, it not only marked the formal end of the war but also laid the groundwork for the post-war geopolitical landscape. The treaty imposed significant reparations and territorial losses on Germany, aimed at preventing future conflicts, although its harsh terms would later be criticized for contributing to the rise of tensions leading to World War II.

The other treaties mentioned do not pertain to the end of World War I. The Treaty of Paris typically refers to treaties that ended the American Revolutionary War and the Spanish-American War, while the Treaty of Tordesillas was an agreement between Spain and Portugal in 1494 concerning the newly discovered lands. The Treaty of Ghent is known for concluding the War of 1812 between the United States and Britain. Each of these treaties addresses different historical contexts and conflicts, emphasizing the significance of the Treaty of Versailles in shaping the aftermath of World War I.
