Nuno was born in 1360, and for many years pursued a military career, becoming the champion of Portuguese
independence. After the death of his wife, he joined the Order as a brother in 1423 at the monastery of Lisbon, which he had founded himself, and took the name of Nuno of Saint Mary. There he lived until his death
in 1431. He was noted for his prayer, his practice of penance, and his filial devotion to the Mother of God.
Nuno was canonized St. Nuno Alvarez on April 26, 2009.
