Not until 150 years later, King Lothair III of Germany re-occupied Havelberg in 1130; the eastern Elbe bank was finally reconquered by the Ascanian margrave Albert the Bear in 1136/37. Its first and most famous Prince-Bishop was the Premonstratensian canon Anselm of Havelberg, who had been anointed already in 1129 by the Magedeburg archbishop Norbert of Xanten. Anselm first took his seat at Jerichow in 1144. Upon the Wendish Crusade in 1147, he was able to found a cathedral chapter at Havelberg and to begin the building of Havelberg Cathedral, which was consecrated in 1170.
