which german state benefited most from the territorial changes made by the congress of vienna
Congress of Vienna A large United Kingdom of the Netherlands was formed for the Prince of Orange, including both the old United Provinces and the formerly Austrian-ruled territories in the Southern Netherlands. Other, less important, territorial adjustments included significant territorial gains for the German Kingdoms of Hanover (which gained East Frisia from Prussia and various other territories in Northwest Germany) and Bavaria (which gained the Rhenish Palatinate and territories in Franconia). The Duchy of Lauenburg was transferred from Hanover to Denmark, and Prussia annexed Swedish Pomerania. Switzerland was enlarged, and Swiss neutrality was established. Swiss mercenaries had played a significant role in European wars for a couple of hundred years: the Congress intended to put a stop to these activities permanently.
Austro-Hungarian Compromise of 1867 As a consequence of the Second Italian War of Independence and the Austro-Prussian War, the Habsburg Empire was on the verge of collapse in 1866, as the wars caused monumental state debt and a financial crisis.[28]
