The Brunswick Manifesto is issued to the population of Paris promising vengeance if the French royal family is harmed.
The Brunswick Manifesto ( named after the County of Brunswick in Germany} was a proclamation issued by Charles William Ferdinand, Duke of Brunswick, commander of the Allied Army (principally Austrian and Prussian), on 25 July 1792 to the population of Paris, France during the War of the First Coalition. The manifesto threatened that if the French royal family were harmed, then French civilians would be harmed. It was said to have been a measure intended to intimidate Paris, but rather helped further spur the increasingly radical French Revolution and finally led to the war between revolutionary France and counter-revolutionary monarchies.
