In contrast to their leaders who had accepted Christianity, the Havolanie population still worshipped old Slavic deities and opposed Albert's assumption of power. Jaxa of Köpenick, a possible relative of Pribislav and a claim-holder to Brandenburg, occupied Brandenburg through guile, violence, and Polish help, and seized the Havelland. Older historical research dates this conquest to 1153, although there are no definite sources for the date. More recent researchers, such as Lutz Partenheimer, date it to spring 1157, as it is doubtful that Albert would not have responded to Jaxa's actions for four years.

With bloody victories on 11 June 1157, Albert the Bear was able to reconquer Brandenburg, exile Jaxa, and found a new lordship. Because he already held the title of margrave, Albert styled himself as Margrave of Brandenburg (Adelbertus Die gratia marchio in Brandenborch) on 3 October 1157, thereby beginning the Margraviate of Brandenburg.

The territorial limits of the original margraviate differed from the area of the current Bundesland Brandenburg
