Upper Saxony
In 1136, upon the death Wiprecht's son Henry of Groitzsch, Lothair, then emperor (as Lothair II), appointed Conrad to Lusatia as well. He also ruled the Milceni lands around Bautzen (later known as Upper Lusatia), which had been re-acquired from Poland and remained a part of Meissen, while the March of Lusatia was reduced to Lower Lusatia alone. Obtaining the status of an Imperial Prince, Margrave Conrad had the Polabian territories colonised by Flemish settlers in the course of the "Ostsiedlung" migration and laid the foundations for the development of the Wettin dominions in Upper Saxony.
