Katarina Šubić

Katarina Šubić (died 1358), daughter of Mladen II Šubić, Ban of Croatia, married Bolesław III the Generous, Duke of Legnica-Brzeg, in 1326, four years after his first wife's death; the marriage was childless. When Bolesław abdicated in 1342 she retired with him to Brzeg.

On his death in 1352 his will left her the Duchies of Brzeg and Oława as her dower, to rule in her own right for life. She reigned over Brzeg for six years, and after her death in 1358 the lands passed to her stepsons Wenceslaus I and Louis I.
