Austro-Prussian War
The pretext for the conflict was found in the dispute between Prussia and Austria over the administration of Schleswig-Holstein, which the two of them had conquered from Denmark and agreed to jointly occupy at the end of the Second Schleswig War in 1864. When Austria brought the dispute before the German Diet and also decided to convene the Diet of Holstein, Prussia declared that the Gastein Convention had thereby been nullified and invaded Holstein. When the German Diet responded by voting for a partial mobilization against Prussia, Bismarck claimed that the German Confederation was ended. Crown Prince Frederick "was the only member of the Prussian Crown Council to uphold the rights of the Duke of Augustenburg and oppose the idea of a war with Austria which he described as "fratricide"". Although he supported unification and the restoration of the medieval empire, "Fritz could not accept that war was the right way to unite Germany."
Charles VII, Holy Roman Emperor
Shortly after the coronation most of Charles Albert's territories were overrun by the Austrians, and Bavaria was occupied by the troops of Maria Theresa. The emperor fled Munich and resided for almost three years in the "Palais Barckhaus" in Frankfurt. Most of Bohemia was lost in December 1742 when the Austrians allowed the French under the Duc de Belle-Isle and the Duc de Broglie an honourable capitulation. Charles Albert was mocked as an emperor who neither controlled his own realm, nor was in effective control of the empire itself, though the institution of the Holy Roman Emperor had largely become symbolic in nature and powerless by that time. A popular Latin saying about him was "et Caesar et nihil", meaning "both Emperor and nothing", a word-play on "aut Caesar aut nihil", "either Emperor or nothing". Charles Albert's general Ignaz Felix, Count of Törring-Jettenbach was compared to a drum, as people "heard about him only when he was beaten".
