peace treaty World War I Allied Powers Palace of Versailles assassination of Archduke Franz Ferdinand Central Powers armistice Paris Peace Conference
The Treaty of Versailles was a peace treaty signed on 28 June 1919. As the most important treaty of World War I, it ended the state of war between Germany and most of the Allied Powers. It was signed in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties.  The United States never ratified the Versailles treaty and made a separate peace treaty with Germany.  Although the armistice of 11 November 1918 ended the actual fighting, it took six months of Allied negotiations at the Paris Peace Conference to conclude the peace treaty. Germany was not allowed to participate in the negotiations; it was forced to sign the final treaty.
