 Prussia intended the annexation of Saxony but the opposition of Austria, France, and the United Kingdom to this plan resulted in the restoration of Frederick Augustus to his throne at the Congress of Vienna although he was forced to cede the northern part of the kingdom to Prussia, which led to the loss of nearly 50% of the Saxon territory.These lands became the Prussian province of Saxony, now incorporated in the modern state of Saxony-Anhalt, except the westernmost part around Bad Langensalza, now in the state of Thuringia.Also Lower Lusatia became part of Province of Brandenburg and northeastern part of Upper Lusatia became part of Silesia Province.
