Franz Joseph I of Austria
If Greater Germany was to prevail, the crown would necessarily have to go to Franz Joseph, who had no desire to cede it in the first place to anyone else. On the other hand, if the idea of a smaller Germany won out, the German crown could of course not possibly go the Emperor of Austria, but would naturally be offered to the head of the largest and most powerful German state outside of Austria—the King of Prussia. The contest between the two ideas, quickly developed into a contest between Austria and Prussia. After Prussia decisively won the Seven Weeks War, this question was solved; Austria lost no territories as long as they remained out of German affairs.
Louis XVI of France
This intervention in America was not possible without France adopting a neutral position in European affairs in order not to be drawn into a continental war which would be simply a repetition of the French policy mistakes in the Seven Years' War. Vergennes supported by King Louis refused to go to War to support Austria in the Bavarian Succession crisis in 1778, when Austrian Holy Roman Emperor, Joseph, tried to control parts of Bavaria. Vergennes and Maurepas refused to support the Austrian position, but the intervention of Marie Antoinette in favor of Austria obliged France to adopt a position more favorable to Austria, which in the treaty of Teschen was able to get in compensation a territory whose population numbered around 100,000 persons. However, this intervention was a disaster for the image of the Queen, who was named ""l'Autrichienne"" (a pun in French meaning "Austrian", but the "chienne" suffix can mean "bitch") on account of it.
