Saint Elizabeth of Hungary, Religious

Memorial

St. Elizabeth of Hungary was a 13th century princess, the daughter of King Andrew II of Hungary and his wife, Gertrude of Andechs-Meran, a family that produced many saints. St. Elizabeth married Ludwig, the duke of Thuringia and their joyous marriage produced three children. She was very generous, donating many of the couple’s possessions to the poor. After Ludwig’s death, St. Elizabeth joined the Third Order of St. Francis. At Marburg, she started a home for the poor, dying, and infirmed, whom she personally tended. She was canonized four years after her death by Pope Gregory IX. [1][2][3]
