St. Elizabeth of Hungary

Saint Elizabeth was married at a young age to Louis of Thuringia, whom she deeply loved, and had three children. Under the spiritual direction of a Franciscan friar, she led a life of prayer, sacrifice, and service to the poor and sick. Seeking to become one with the poor, she wore simple clothing. Daily she would take bread to hundreds of the poorest in the land who came to her gate.  

After six years of marriage, her husband died in the Crusades, and Elizabeth was grief-stricken, and was maltreated by her husband's family.  With the return of her husband’s allies from the Crusades, she was reinstated to royalty, since her son was the rightful heir. Using her royal position, she advanced her mission for charity.  In 1228, Saint Elizabeth joined the Secular Franciscan Order, spending the remaining few years of her life caring for the poor in a hospital which she founded in honor of Saint Francis of Assisi.  She led an austere simple life, practiced penance, and devoted herself to works of charity.   Her health declined, and she died before her 24th birthday in 1231. She was canonized four years later.
