Amadeus of Portugal, O.F.M., (1420–1482), was a Portuguese nobleman who became first a monk, then left that life to become a friar of the Franciscan Order. Later he became a reformer of that Order, which led to his founding of a distinct branch of the Friars Minor that was named after him, later suppressed by the Pope in order to unite them into one great family of Friars Minor Observants (1568).
