In August 1791, Frederick Augustus arranged a meeting with Holy Roman Emperor Leopold II and King Friedrich Wilhelm II of Prussia at Pillnitz Castle. The move was intended partly to offer support for the French monarchy in the face of revolutionary agitation in France. The Declaration of Pillnitz warned of the possibility of military action against the French revolutionary government, a provocation that provided the latter with grounds to declare war on Austria in April 1792. Frederick Augustus himself did not sign the Declaration.
