Miliduch
Miliduch (also Miliduh and , , ; d. 806) was a knyaz of the Lusatian Serbs (Sorbs). Formerly allied to Charlemagne, the Sorbs ended their vassalage to the Franks and rebelled, invading Austrasia. Charles the Younger launched a campaign against the Slavs in Bohemia in 805, and after killing Duke Lecho of the Bohemians, Charles himself crossed the Saale with his army and killed Miliduch and knyaz Nussito (Nessyta), near modern-day Weißenfels, in 806. The region was laid to waste, upon which the other Slavic chieftains submitted and gave hostages.
