Ems Dispatch

The Ems Dispatch (French: Dépêche d'Ems, German: Emser Depesche), sometimes called the Ems Telegram, caused France to declare the Franco-Prussian War in July 1870. The actual dispatch was an internal message from the Prussian King's vacationing site to Bismarck in Berlin, reporting demands made by the French ambassador; it was Bismarck's released statement to the press that became known as Ems Dispatch. The name referred to Bad Ems, a resort spa east of Koblenz on the Lahn river, then situated in Hesse-Nassau, a new possession of Prussia.
