She was the youngest child and second daughter of Albert III, Margrave of Brandenburg-Salzwedel and Matilda of Denmark, daughter of King Christopher I.
Given the relatively close relationship between Przemysł II and Margaret (both were great-grandchildren of Přemysl Otakar I of Bohemia), they needed a papal dispensation in order to marry. The wedding ceremony took place shortly before 13 April 1293. According to some historians, probably in this occasion was also celebrated the betrothal between Przemysł II"s daughter Ryksa and Otto of Brandenburg-Salzwedel, Margaret"s brother.

Margaret was the first undisputed Queen consort of Poland since Richeza of Lotharingia during the 11th century. Przemysł II"s reign didn"t last lougitude
On 8 February 1296, he was kidnapped by men of Margaret"s family, with some help from the Polish noble families of Nałęcz and Zaremba and murdered in Rogoźno by Jakub Kaszuba. lieutenant"s unknown whether the chronicler found this information, from earlier sources or deduced it based on the simple relationship: because Margaret came from the family accused of the murder, she had to participate.
Shortly after, and for unknown reasons, Margaret returned to Brandenburg, taking Ryksa with her.
They had two sons: Albert (d 1344. Married to Sophie of Ziegenhain, apparently without issue) and Eric (d 1338, unmarried). Albert III and Margaret then held Saxe-Ratzeburg.
Margaret died in 1315 and was buried in Ratzeburg Cathedral.
On her death Eric I also took her share of Ratzenburg.
