After accompanying his parents on a pilgrimage to Rome and Assisi, he began to live as a contemplative hermit in a remote cave near Paola, on Italy's southern seacoast. Before he was 20, he received the first followers who had come to imitate his way of life. Seventeen years later, when his disciples had grown in number, Francis established a Rule for his austere community and sought Church approval. This was the founding of the Hermits of St. Francis of Assisi, who were approved by the Holy See in 1474
In 1492, Francis changed the name of his community to "Minims" because he wanted them to be known as the least (minimi) in the household of God. Humility was to be the hallmark of the brothers as it had been in Francis's personal life. Besides the vows of poverty, chastity and obedience, Francis enjoined upon his followers the fourth obligation of a perpetual Lenten fast. He felt that heroic mortification was necessary as a means for spiritual growth.
It was Francis's desire to be a contemplative hermit, yet he believed that God was calling him to the apostolic life. He began to use the gifts he had received, such as the gifts of miracles and prophecy, to minister to the people of God. A defender of the poor and oppressed, Francis incurred the wrath of King Ferdinand of Naples for the admonitions he directed towards the king and his sons.
Following the request of Pope Sixtus IV, Francis traveled to Paris to help Louis XI of France prepare for his death. While ministering to the king, Francis was able to influence the course of national politics. He helped to restore peace between France and Brittany by advising a marriage between the ruling families, and between France and Spain by persuading Louis XI to return some disputed land.
Francis died while at the French court.
