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."
Maximilian III Joseph, Elector of Bavaria
Upon his father's death in January 1745, he inherited a country in the process of being invaded by Austrian armies (see War of the Austrian Succession). The 18-year-old Maximilian Joseph wavered between the "Peace-party", led by his mother Maria Amalia of Austria and Army Commander Friedrich Heinrich von Seckendorff and the "War-party", led by Foreign Minister General Ignaz Count of Törring and the French envoy Chavigny. After the decisive defeat in the Battle of Pfaffenhofen on 15 April Maximilian Joseph quickly abandoned his father's imperial pretenses and made peace with Maria Theresa in the Treaty of Füssen, in which he agreed to support her husband, Grand Duke Francis Stephen of Tuscany, in the upcoming imperial election. During the Seven Years' War Bavarian forces then fought on the Habsburg side. Maximilian Joseph's sister Maria Josepha of Bavaria was married in 1765 to Maria Theresa's son Emperor Joseph II. But long-term weakening of Prussia was not in the Bavarian interest, as that country offered the only counterweight to the Habsburg monarchy. Maximilian Joseph tried, as far as possible, to keep Bavaria out of the wars. Apart from militia troops, he sent only a small force of 4,000 men to join the Austrian army. In 1758/1759 (only a year and half into the war), he withdrew Bavarian auxiliary troops from Austrian service. Together with the Wittelsbach Elector Charles Theodore of the Palatinate he enforced the neutrality of the Empire during the conflict.
