Today in History: World War I

Today in History–June 28–the Library of Congress features World War I. Two events bracketing this global conflict happened on June 28. The assassination of Archduke Francis Ferdinand of Austria and his wife Sofia in Sarajevo on June 28, 1914, set off a chain of events leading to the first world war. Five years later, on June 28, 1919, Germany and the Allies signed the Treaty of Versailles, formally ending World War I. Find out more by visiting the Today in History section, then follow the links below to access thousands more World War I resources.
