St. Francis of Assisi (Italian: San Francesco d'Assisi, born Giovanni di Pietro di Bernardone, but nicknamed Francesco ("the Frenchman") by his father, 1181/1182 – October 3, 1226) was an Italian Catholic friar and preacher. He founded the men's Order of Friars Minor, the women’s Order of St. Clare, and the Third Order of Saint Francis for men and women not able to live the lives of itinerant preachers followed by the early members of the Order of Friars Minor or the monastic lives of the Poor Clares. Though he was never ordained to the Catholic priesthood, Francis is one of the most venerated religious figures in history.

Francis' father was Pietro di Bernardone, a prosperous silk merchant. He lived the high-spirited life typical of a wealthy young man, even fighting as a soldier for Assisi. While going off to war in 1204, Francis had a vision that directed him back to Assisi, where he lost his taste for his worldly life. On a pilgrimage to Rome, he joined the poor in begging at St. Peter's Basilica. The experience moved him to live in poverty. Francis returned home, began preaching on the streets, and soon amassed a following. His Order was authorized by Pope Innocent III in 1210. He then founded the Order of Poor Clares, which became an enclosed religious order for women, as well as the Order of Brothers and Sisters of Penance (commonly called the Third Order).
