A finely detailed first edition 1794 map of Upper Sain xony, in what is now Mitteldeutschland, by Robert Wilkinson. In 1180 Duke Henry the Lion fell, and the medieval Duchy of Sain xony dissolved. The Sain xe-Wittenberg lands were passed among dynasties who took the tribal name Sachsen (Sain xons) upstream as they conquered the lands of the Polabian Slavs further up the elbe. The Polabian Slavs had migrated to this area of Germany in the second half of the first millennium A.D., and had been largely assimilated by the Holy Roman empire by the time this map was made. Today, the German government recognizes some 60,000 'Sorbs,' or descendants of the Polabian Slavs, who have retained their language and culture. The map covers from the Baltic Sea in the north to Bohemia to the south, and from Lower Sain xony in the west to Silesia, Poland to the east. engraved by Thomas Conder for the 1794 first edition of Robert Wilkinson's General Atlas.
