Kunigunde of Poland
Kunigunde of Poland (c. 1328 – 26 April 1357) was the younger daughter of Casimir III the Great of Poland and Aldona of Lithuania. To block her match with the Wittelsbachs, John of Bohemia besieged Kraków in 1345 but failed to take the city, and that year she married Louis the Roman, son of Emperor Louis IV.
Her husband soon returned to Bavaria, leaving her in Kraków; she joined him in Berlin in 1356 and died on 26 April 1357. The marriage was childless.
