St. Margaret was born to Emperor Bela IV and Mary Lascaris in 1242. She was placed in the Monastery of Veszprem for her education and later, she received the Dominican habit in Buda. She made profession to Humbert of Romans, fifth Master General, at a meeting of the General Chapter at Buda in 1254. Margaret lived a life totally dedicated to Christ crucified and inspired her sisters by her asceticism, works of mercy, pursuit of peace and humble service. A vivid picture of her characteristics is furnished in her acts of canonization by the nuns who lived with her. She lived in total humility, engaging in the most menial tasks even in the winter when her hands bled from the cold. She constantly fasted and refused nice clothes and royal comforts, remarking that she preferred the odor of sanctity when dead to smelling sweet only when alive. She spent her days in prayer, devotion to the Eucharist, and caring for the poor, lavishing on them whatever gifts her royal family sent her. She died in 1270, and Pope Pius XII canonized her in 1943.
