In 1269, 1272, and 1282, they gradually divided their governing competences within the then three territorially unconnected Saxon areas (Hadeln, Lauenburg, and Wittenberg), thus preparing a partition, whereby Albert II, Burgrave of Magdeburg since 1269, concentrated on the Wittenberg territory.
From 1269 to 1282, they gradually divided their administrative authority among three separate Saxon territories (Hadeln, Lauenburg, and Wittenberg). This division led to Albert II, Burgrave of Magdeburg since 1269, taking control of the Wittenberg region.
