Northern March
Albert's entanglements in Saxony stemmed from his desire to expand his inherited estates there. After the death of his brother-in-law, Henry II, Margrave of the Nordmark, who controlled a small area on the Elbe called the Saxon Northern March, in 1128, Albert, disappointed at not receiving this fief himself, attacked Udo V, Count of Stade, the heir, and was consequently deprived of Lusatia by Lothar. Udo, however, was said to have been assassinated by servants of Albert on 15 March 1130 near Aschersleben. In spite of this, Albert went to Italy in 1132 in the train of the king, and his services there were rewarded in 1134 by the investiture of the Northern March, which was again without a ruler.
