Pius of Saint Aloysius, born Luigi Campidelli, was an Italian Passionist cleric who lived from 1868 to 1889. Raised in a farming family in Poggio Berni, he demonstrated early religious devotion and a strong loyalty to the papacy. He entered the Passionist order in 1882 and took his vows in 1884. Although he died from tuberculosis before he could be ordained as a priest, he was recognized for his profound faith and commitment to his religious community. He was beatified by Pope John Paul II in 1985.
