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.
History of Germany The concept of Germany as a distinct region in central Europe can be traced to Roman commander Julius Caesar, who referred to the unconquered area east of the Rhine as Germania, thus distinguishing it from Gaul (France), which he had conquered. The victory of the Germanic tribes in the Battle of the Teutoburg Forest (AD 9) prevented annexation by the Roman Empire, although the Roman provinces of Germania Superior and Germania Inferior were established along the Rhine. Following the Fall of the Western Roman Empire, the Franks conquered the other West Germanic tribes. When the Frankish Empire was divided among Charlemagne's heirs in 843, the eastern part became East Francia. In 962, Otto I became the first emperor of the Holy Roman Empire, the medieval German state.
