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.
Seven Years' War
Not only that, Austria now found herself estranged with the new developments within the empire itself. Beside the rise of Prussia, Augustus III, although ineffective, could muster an army not only from Saxony, but also Poland, since he was also the King of Poland as well as Elector of Saxony. Bavaria's growing power and independence was also apparent as it asserted more control on the deployment of its army, and managed to disengage from the war at its own will. Most importantly, with the now belligerent Hanover united personally under George III of Great Britain, It amassed a considerable power, and even brought Britain in, on future conflicts. This power dynamic was important to the future and the latter conflicts of the "Reich". The war also proved that Maria Theresa's reforms were still insufficient to compete with Prussia: unlike its enemy, the Austrians were almost bankrupt at the end of war. Hence, she dedicated the next two decades to the consolidation of her administration.
