[2] 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.
The manifesto was written primarily by Louis Joseph, Prince of Condé, the leader of a large corps of French émigrés in Brunswick's army, and intended to intimidate Paris into submission.
Brunswick maintained a secret correspondence with Louis XVI and Marie Antoinette, and two days before making the Manifesto public, he sent a copy to the Tuileries Palace, and both the King and the Queen approved it.
The prevailing historiographical tradition suggests that the Brunswick Manifesto, rather than intimidate the populace into submission, sent it into furious action and created fear and anger towards the Allies.
It also spurred revolutionaries to take further action, organizing an uprising – on 10 August, the Tuileries Palace was stormed in a bloody battle with Swiss Guards protecting it, the survivors of which were massacred by the mob.
