Jadwiga of Poland

Jadwiga , also known as Hedwig , reigned as the first female monarch of the Kingdom of Poland from 1384 until 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.

Jadwiga was the youngest daughter of Louis I, King of Hungary and Poland, and his second wife, Elizabeth of Bosnia. Her grandmothers were Polish princesses, connecting her to the native Piast dynasty of Poland. Historian Oscar Halecki concluded that Jadwigas genealogical tree clearly shows that had more Polish blood than any other. She was born in Buda.
