About this source
What it is
The Ems dispatch was a telegram sent by Heinrich Abeken from King Wilhelm I in Bad Ems to Otto von Bismarck in Berlin, describing a meeting between the king and the French ambassador. Bismarck released an edited version to the press on 13 July 1870.
Why it matters
Bismarck's shortened, sharper version made both the French ambassador and the king sound more hostile than the original wording suggested. The edited text helped push France into declaring war on Prussia within days, starting the Franco-Prussian War. It shows how Bismarck used the press as a political weapon.
