Вратислав II
In 1073, the Saxons, led by Duke Magnus and Otto of Nordheim, rebelled against King Henry IV. The insurrection was crushed by Duke Vratislaus II of Bohemia in the First Battle of Langensalza on 9 June 1075. Whether Egbert had participated in the Saxon rebellion remains unclear based on extant sources, but since he had nonetheless proved himself an opponent of the king, he 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.
