Jadwiga , also known as Hedwig (; 1373/4 – 17 July 1399), reigned as the first female monarch of the Kingdom of Poland from 1384 to her death. She was the youngest daughter of Louis the Great, King of Hungary and Poland, and his wife, Elizabeth of Bosnia. Jadwiga was a member of the Capetian House of Anjou, but she was even more closely related to the native Piast dynasty of Poland through her ancestors. She was canonized in 1997.
