What happened
A dispute over a Hohenzollern prince's candidacy for the vacant Spanish throne led the French ambassador, Count Vincent Benedetti, to approach Prussian King Wilhelm I during his stay at the spa town of Ems on 13 July 1870, pressing him to permanently renounce any future Hohenzollern claim to the Spanish crown. Wilhelm politely declined to commit to anything indefinite and had his aide, Heinrich Abeken, send Bismarck a factual telegram describing the exchange. Bismarck edited the wording before releasing it to the press, sharpening the language to make the encounter sound like a mutual insult between the king and the ambassador, and the altered Ems Dispatch as published incited public outrage in both France and the German states, with the French government declaring war on Prussia six days later, on 19 July 1870.
Why it matters
The engineered crisis achieved exactly what Bismarck wanted: French aggression that made Prussia appear the victim, uniting the southern German states, which had stayed out of the 1866 war, behind Prussia against a common enemy. The resulting Franco-Prussian War would end with Prussia victorious, France's Second Empire collapsed, and the German Empire proclaimed within six months.
How we know
The original two-page Ems Dispatch document survives and is preserved in facsimile and translation by the German Historical Institute's document archive, alongside Bismarck's own later account of how he edited it before release to the press.
