In 1176 she married Otto I of Brandenburg, becoming Margravine of Brandenburg until his death in 1184. This was Otto's second marriage. He had been married to Judith of Poland. Otto already had two sons from his marriage to Judith, Otto (who later succeeded his father as Margrave of Brandenburg) in 1149, and Henry (who inherited the Counties of Tangermünde and Gardelegen) in 1150.^[2]
