After the death of her father (1471), she became the potential heiress of Oleśnica and perhaps all the duchy; for this, she remained under the care of her mother and the formal guardianship of her childless uncle Konrad X the White.
In the summer of 1472 Konrad X engaged her with Albert, the eldest son of Henry I the Elder, Duke of Ziębice.
On this occasion, Konrad X sold to Henry I for 9,000 guilders the towns of Koźle, Toszek and Bytom.
However, soon the betrothal was broken; Albert eventually married with Salome, daughter of Jan II the Mad, Duke of Głogów, in 1487.
In 1475, Margareta of Rawa was deposed by Konrad X from the effective government over Oleśnica and Bierutów (which were given to her as her dower) and replaced by her own daughter Barbara, who remained as a sovereign duchess (but under the tutelage of her uncle), until 1478, when she was also deposed by Konrad X, who took the direct control over Oleśnica.
