By 1240, he became interested in the religious life and decided to become a friar with the new Dominican Order. His family captured him and brought him back because to become a Dominican one must eliminate material wealth. His parents expected him to follow in his uncle’s footsteps and become a Benedictine abbot. They kept him in a castle in an effort to change his mind. However, when they released him two years later, he immediately joined the Dominicans.
