Rudolf II (died 14 March 1144), Margrave of the Nordmark, and Count of Stade, Dithmarschen and Freckleben, son of Rudolf I, Margrave of the Nordmark, and Richardis, daughter of Hermann von Sponheim, Burgrave of Magdeburg.
Rudolf, the traditional heir to the margraviate assumed the title upon the death of his predecessor Conrad von Plötzkau.
[1] Rudolf was married to Elisabeth, daughter of Leopold I the Strong, Margrave of Styria.
After the death of Rudolf, his brother Hartwig transferred his inheritance to the Archbishopric of Bremen in return for a regrant of a life interest, presumably to obtain a powerful protector against the aggression of Henry the Lion.
The move was ineffective, as Henry took possession of the lands and captured both Hartwig and the archbishop Adelbero, releasing them only after they agreed to recognize his claim.
