St. Catherine of Siena
As a mystic and Doctor of the Church, St Catherine used her gifts of philosophy and theology to encourage peace among the Italian territories of her time. She worked tirelessly for the crusade against the Turks and for peace between Florence and the Pope and was instrumental in restoring the Papacy to Rome. She also established a monastery for women in 1377 outside of Siena.
During her time St Catherine also composed over 400 letters which became so influential that she was later declared a Doctor of the Church.
