Saint Francis of Assisi (1182 – 4 October 1226) founded the Franciscan Order or "Friars Minor". He is the patron saint of animals, merchants, Catholic action and the environment. Born Giovanni Bernardone, commonly known as Francesco. He was either born in 1181 or 1182. His father, Pietro, was a wealthy cloth merchant. Of his mother, Pica, little is known. Francis was one of several children.

Rebellious toward his father's business and pursuit of wealth, Francis would spend most of his youth lost in books (ironically, his father's wealth did afford his son an excellent education, and he became fluent in reading several languages including Latin). He was also known for drinking and enjoying the company of his many friends, who were usually the sons of nobles. His displays of disillusionment toward the world that surrounded him became evident fairly early, one of which is shown in the story of the beggar. In this account, he found himself out having fun with his friends one day when a beggar came along and asked for alms. While his friends ignored the beggar's cries, Francis gave the man everything he had in his pockets. His friends quickly chided and mocked him for his stupidity, and when he got home, his father scolded him in a rage.

In 1201 he joined a military expedition against Perugia, was taken prisoner, and spent a year as a captive. It is probable that his conversion to more serious thoughts was a gradual process relating to this experience.

It is said that when he began to avoid the sports of his former companions, and they asked him laughingly if he was thinking of marrying, he answered "Yes, a fairer bride than any you have ever seen" - meaning his "lady poverty", as he afterward used to say.

He spent much time in lonely places, asking God for enlightenment. By degrees he took to nursing the most repulsive victims in the lazar houses near Assisi.

After a pilgrimage to Rome, where he begged at the church doors for the poor, he had a vision in which he heard a voice calling upon him to restore the Church of Jesus which had fallen into decay. He thought this to mean the ruined church of St. Damian near Assisi and sold his horse together with some cloth from his father's store, giving the proceeds to the priest for this purpose.

Pietro, highly indignant, attempted to bring him to his senses, first with threats and then with corporal chastisement. After a final interview in the presence of the bishop, Francis renounced all expectations from his father, laying aside even the garments received from him, and for a while was a homeless wanderer in the hills around Assisi.

Returning to the town where he spent two years this time, he restored several ruined churches, among them the little chapel of St Mary of the Angels, Assisi, just outside the town, which later became his favorite abode.
