He labored diligently in Rome founding the Vatican Academy for literary work and other interests of the church. He was instrumental in assembling the Council of Trent, enforcing its reforms, and composing the Roman Catechism. After his ordination he accepted the office of grand penitentiary. The Pope died in 1564 with Charles at his side. After Pius V was elected, Charles went to Milan. He showed himself the true shepherd by his self-sacrificing during the great plague in Milan in 1575. He died in 1584.
