Vratislaus II of Bohemia
In 1073, the Saxons, led by Magnus, Duke of Saxony and Otto of Nordheim, rebelled against emperor Henry IV. The insurrection was crushed by Duke Vratislaus II of Bohemia in the First Battle of Langensalza on 9 June 1075. Since he had proved himself an opponent of the king, Egbert II was deprived of Meissen, which was given to Vratislaus. However, Egbert drove Vratislaus from Meissen the next year and was condemned. A Frisian county then in his possession was confiscated and given to the Bishop of Utrecht.
