Background
She was the third child and eldest daughter of Duke Bolko III of Münsterberg by his wife Euphemia, daughter of Duke Bolesław of Bytom.
She was the third child and eldest daughter of Duke Bolko III of Münsterberg by his wife Euphemia, daughter of Duke Bolesław of Bytom.
In 1397 Euphemia married with the widower Count Frederick III of Oettingen. Perhaps under her influence, a German translation of the "of Saint Hedwig of Andechs" with rich colors and illustrations was made, which remained in the Comital Library of Oettingen. On 11 November 1435, Euphemia was formally invested as Duchess of Ziębice.
In order to revenge, the Duchess ordened Sigismund of Rachenau, the castellan of Neuhaus (Chałupki) to plunder and burn the monastery of Heinrichau in 1438.
After definitely losing the government of the Duchy, Euphemia returned to Germany. She died four years later.
