The Treaty of Versailles was a treaty signed to officially end World War I after the Armistice brought it to a ceasefire. It was signed on June 28, 1919 and became effective on January 10, 1920.


The treaty's name in full is the "Treaty of Peace between the Allied and Associated Powers and Germany". It is called the "Treaty of Versailles" due to the fact it was signed in the Hall of Mirrors in the Palace of Versailles in France.
