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."
Austria (Lombard)
Austria included the duchies of the north-eastern Lombard Kingdom, among them a prominent role was covered by:The duchies of Austria presented themselves as the defenders of the warrior and conqueror spirit of the Lombards. Here survived longer than in other places the old pagan cults and among the converts to Christianity, many were adherents of Arianism or adherents to the Schism of the Three Chapters. The Dukes of "Austria" pressed repeatedly on the king to take initiative, coming in several times to hatch conspiracies to overthrow the legitimate sovereign. This was the case in 662 of Grimoald (duke of Benevento, but a son of a Duke of Friuli), who managed to usurp the throne of Godepert and Perctarit despite the opposition of the Neustrians dukes of Asti and Turin; of Alahis, Duke of Trent, who in 688-689 was able to seize the throne of Pavia before being defeated by Cunipert; of Ansfrid of Friuli, who, having usurped the Duchy of Friuli, in turn attempted to seize the throne of Cunipert (who defeated and killed him in 698); of Rotarit, Duke of Bergamo, who after the death of Cunipert objected unsuccessfully to Raginpert first and then Aripert II (700-702). In the 8th century, however, the widespread conversion of the Lombards to Catholicism smoothed the opposition between "Austria" and "Neustria", thanks to a revived expansion at the expense of the Byzantine Empire with the Catholic and Neustrian Liutprand (king from 712).
