Article 231 of the Treaty of Versailles

Article 231, often known as the War Guilt Clause, was the opening article of the reparations section of the Treaty of Versailles, which ended the First World War between the German Empire and the Allied and Associated Powers. The article did not use the word "guilt" but it served as a legal basis to compel Germany to pay reparations for the war.

Article 231 was one of the most controversial points of the treaty. It specified:

Germans viewed this clause as a national humiliation, forcing Germany to accept full responsibility for causing the war. German politicians were vocal in their opposition to the article in an attempt to generate international sympathy, while German historians worked to undermine the article with the objective of subverting the entire treaty. The Allied leaders were surprised at the German reaction; they saw the article only as a necessary legal basis to extract compensation from Germany. The article, with the signatory's name changed, was also included in the treaties signed by Germany's allies who did not view the clause with the same disdain as the Germans did. American diplomat John Foster Dulles—one of the two authors of the article—later regretted the wording used, believing it further aggravated the German people.

The historical consensus is that responsibility or guilt for the war was not attached to the article. Rather, the clause was a prerequisite to allow a legal basis to be laid out for the reparation payments that were to be made. Historians have also highlighted the unintended damage created by the clause, which caused anger and resentment amongst the German population.

On 28 June 1914 the Bosnian-Serb Gavrilo Princip assassinated the heir to the throne of Austria-Hungary, Archduke Franz Ferdinand, in the name of Serbian nationalism. This caused a diplomatic crisis, resulting in Austria-Hungary declaring war on Serbia and sparking the First World War. Due to a variety of reasons, within weeks the major powers of Europe—divided into two alliances known as the Central Powers and the Triple Entente—went to war. As the conflict progressed, additional countries from around the globe became drawn into the conflict on both sides.
