What treaty officially concluded World War I?

The Treaty of Versailles is recognized as the official treaty that concluded World War I. Signed on June 28, 1919, it laid out the terms of peace between the Allied Powers and Germany following the tremendous destruction and loss of life during the war. This treaty not only formally ended hostilities but also imposed significant reparations and territorial losses on Germany, which played a crucial role in shaping the political landscape of Europe in the years following the war.

The Treaty of Versailles is significant because it aimed to address the causes of the war and establish a framework for future international relations, ultimately leading to the formation of the League of Nations as a means to prevent such conflicts. Its effectiveness and fairness have been debated by historians, especially considering the impact it had on Germany and the rise of subsequent tensions that led to World War II.

While other treaties mentioned, such as the Treaty of Paris or the Treaty of Ghent, are notable in their historical contexts, they do not pertain to the conclusion of World War I. The Treaty of Tordesillas, for example, was an agreement between Spain and Portugal in 1494 regarding the division of newly discovered lands, which is unrelated to this specific conflict.
