Oberlausitz
The newly established Kingdom of Saxony, however, sided with Napoleon; therefore, at the 1815 Congress of Vienna, Lusatia was divided, with Lower Lusatia and the northeastern part of Upper Lusatia around Hoyerswerda, Rothenburg, Görlitz and Lauban awarded to Prussia. Only the southwestern part of Upper Lusatia, which included Löbau, Kamenz, Bautzen and Zittau, remained part of Saxony.
