Альбрехт Медведь
The baptized Hevelli prince Pribislav (died 1150) finally bequested his lands to the Ascanian count Albert the Bear. Albert until 1157 could re-conquer the territory of the former Northern March, whereafter he established the Margraviate of Brandenburg. The Slavic Hevelli were gradually assimilated by German settlers in the course of the "Ostsiedlung".
