Beatrice of Hungary, Dauphine of Viennois
Hungarian noble (1290–1343)
From Wikipedia, the free encyclopedia
Beatrice of Hungary (1290–1343 or 1354) was a Dauphine of Viennois by marriage to John II of Viennois.

Life
She was the elder daughter and the second of Charles Martel of Anjou and Klementia of Habsburg's three children,[1] making her a member of the Capetian House of Anjou. Beatrice was thus maternal granddaughter of Rudolf I of Germany and sister of Charles I of Hungary and Clementia of Hungary.
In 1296, when Beatrice was just six years old, she was married to John II of Viennois, who was ten years her senior in Naples.[1] The couple had two sons: Guigues VIII and Humbert II.
When her husband died in 1319, Beatrice became a nun at Cîteaux. She remained here until 1340, when she transferred to the Saint-Just-de-Claix Abbey. Her son founded the convent of Saint-Just dans le Royannais for her.
Beatrice died in 1343 (or 1354) in the convent her sons had founded for her.
