Barbara of Oleśnica was a member of the House of Piast and Duchess of Oleśnica during 1475–1478.
Background
She was the only child of Konrad IX the Black, Duke of Oleśnica by his wife Margareta, daughter of Duke Siemowit V of Rawa. After the death of her father (1471), she became in the potential heiress of Oleśnica and perhaps all the Duchy. Foreign this, she remained under the care of her mother and the formal guardianship of her childless uncle Konrad X the White.
Career
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 January II the Mad, Duke of Głogów, in 1487.
The last mention of Barbara was by 30 November 1479. She probably died shortly afterwards.
