Elisabeth (Beatrice) of Swabia

Elisabeth of Swabia, known in Castile as Beatrice (1205–1235), was a Hohenstaufen princess, daughter of the German king Philip of Swabia and Irene Angelina. After her father's murder and her mother's death in 1208, she came under the guardianship of her cousin Frederick, who arranged her marriage to Ferdinand III of Castile in 1219. She became queen of Castile and, in 1230, of León.

She bore ten children, including Alfonso X the Wise and Manuel. She died in 1235, probably in childbirth; first buried at Las Huelgas, she was later moved by Alfonso X to Seville Cathedral.
