Elizabeth of Poland

Elizabeth of Poland (1305–1380), daughter of Władysław I the Elbow-high and sister of Casimir III, became queen of Hungary by marriage to Charles I Robert. She founded a Poor Clares convent at Buda in 1334 and survived an assassination attempt that left her disabled.

After her son Louis I took the throne in 1342 she became queen mother. In 1343 she travelled to Naples with almost the whole royal treasure to win the crown for her son Andrew, husband of Queen Joanna, winning only a promise that he would be crowned as consort.

When Casimir died in 1370 and Louis inherited Poland, she governed there as regent until 1376, a regency that ended in violence. She spent her last years in a monastery outside Buda, and died on 29 December 1380.
