There is entire section dedicated to Lusatian Serbs and Slavs of the region
A most interesting site. Thank you very much! Have you read the : The Conversion and Destruction of the Wends (1980) by E. L. Skip Knox provided in one of the links under the "History" section?
The book clearly states that for: [the] three centuries of alternating advances and retreats left the [north-eastern] frontier of the [Holy Roman] Empire in 1100 almost exactly where it had been in 800
Thus the Western Slavs of Polabia (or the Wends) had managed to keep the Elbe-Saale line as a frontier between the Germanic and Slavic worlds for three hundred years until their culture and language vanished almost completely from the world!
So the real question should be: when will the Germans give back Slavic land and the cities which they robbed [among others: Halle, Leipzig, Dresden, Rostock and Berlin] ?
