Elizabeth of Hungary, Duchess of Bavaria

Elizabeth of Hungary (Árpád-házi Erzsébet, Elisabeth von Ungarn, 1236 – 25 October 1271) was a medieval Hungarian noble lady from the Árpád dynasty as a daughter of Béla IV, King of Hungary. She became the duchess of Lower Bavaria as the wife of Henry XIII, Duke of Bavaria. She was the mother of Otto, King of Hungary.

Life
Elizabeth was born around 1236 to Béla IV and his Greek wife, Queen Maria Laskarina as their fifth child. Born shortly after the canonisation of her aunt, Elizabeth of Hungary in May 1235, she was named after her. Around 1244, or as late as 1250, she was married to Henry of Bavaria, a younger son of the then-reigning duke of Bavaria and count palatine of the Rhine, Otto II, which was recorded in the Annales Altahenses. In 1253, her husband and her brother-in-law inherited Bavaria and the Palatinate from their father, dividing it between themselves. Henry ruled over Lower Bavaria. Elizabeth died on 24 October 1271 and was buried in. Her death was recorded in the abbey's necrology as well as in those of Tegernsee Abbey and Windberg Abbey, and in the Annales Altahenses, all naming her as ducissa Bawarie, 'duchess of Bavaria'.
