Vratislaus II of Bohemia
During the 10th–12th centuries, the region of Bautzen was known in written sources (e.g. Thietmar of Merseburg) as "Gau Milsca". Temporarily conquered by the Polish king Bolesław I the Brave, the Milceni lands returned under German rule by 1031. In Polish, Upper Lusatia was known as "Milsko" until the 15th century. The Milceni were still mentioned in the 12th century "Song of Roland" ("the second of big-headed men from Misnes– along the vertebrae all down their backs these men have tufted bristles, just like hogs"). Enfeoffed to Duke Vratislaus II of Bohemia in 1076, their estates later became known as "Land Budissin" and Upper Lusatia.
