Brunswick Manifesto - French Revolution Wars
Check out the outfit! This is the Duke of Brunswick who wrote a nasty message to the people of France on 25 July 1792. In essence, he stated "if Parisians harm King Louis XVI, we will destroy Paris...". "We", referring to the Austrian and German armies.
The "Brunswick Manifesto" is an attempt from Austria and Prussia to stop the French Revolution. A coalition of monarchies soon to be joined by England and Spain.
The threat caused the exact opposite! When this document was read at the Convention Nationale, it greatly contributed in accelerating the war and tilting the Revolution towards a more radical direction.
