Альбрехт Медведь
After the Wendish crusade, Albert the Bear was able to establish and expand the Margraviate of Brandenburg in 1157 on approximately the territory of the former Northern March, which since 983 had been controlled by the Hevelli and Lutici tribes. The Bishopric of Havelberg, that had been occupied by revolting Lutici tribes was reestablished to Christianize the Wends.
