Fulvio Giulio della Corgna
Fulvio Giulio della Corgna was born in Perugia on November 19, 1517, the son of Francia della Corgna, a Perugian nobleman, and Jacopa Ciocchi del Monte. His mother was the sister of Pope Julius III and niece of Cardinal Antonio Maria Ciocchi del Monte.
He joined the Knights Hospitaller at an early age, taking the religious name "Giulio" in honor of his family's benefactor, Pope Julius II. He entered the court of his uncle, Cardinal Giovanni Maria Ciocchi del Monte, the future Pope Julius III.
In 1553, Cosimo de' Medici, Duke of Florence requested that Cardinal della Corgna be named administrator of Spoleto to quell disturbances that had broken out there; as such, on March 22, 1553, he resigned the government of Perugia to become administrator of Spoleto.
He was a participant in both the papal conclave of April 1555 that elected Pope Marcellus II and the papal conclave of May 1555 that elected Pope Paul IV. Pope Paul IV deprived him of the administration of Spoleto in 1555. When the pope learned that Cardinal della Corgna had warned his brother Ascanio della Corgna of the pope's orders to arrest him for illicitly entering into communications with Philip II of Spain, the pope had the cardinal arrested on his way to the consistory of July 27, 1556. He was imprisoned in the Castel Sant'Angelo. Following Spanish victories, the pope was forced to moderate his position and ordered the cardinal released and restored to his cardinalate duties, though the cardinal was still fined 60,000 scudi.
On September 20, 1557, he opted for the titular church of Santo Stefano Rotondo. He participated in the papal conclave of 1559 that elected Pope Pius IV. In 1560, the new pope made him governor of Città della Pieve. He served as the Camerlengo of the Sacred College of Cardinals from January 15, 1561 until January 9, 1562. On May 18, 1562, he opted for the titular church of Sant'Agata dei Goti, a deaconry raised temporarily to the status of titulus. He was assigned to the Diocese of Perugia for a second time on September 6, 1564. On February 7, 1565, he opted for Sant'Angelo in Pescheria, another deaconry assigned as titulus, on February 7, 1565.
He participated in the papal conclave of 1565-66 that elected Pope Pius IV. On January 30, 1566, he opted for the titular church of San Lorenzo in Lucina, and then, on March 3, 1567, for Sant'Adriano al Foro, another deaconry assigned as titulus.
He participated in the papal conclave of 1572 that elected Pope Gregory XIII. As the most senior priest residing in the Roman Curia, he opted for the order of cardinal bishops on May 5, 1574, taking the suburbicarian Diocese of Albano. Because of the new decrees of the Council of Trent forbidding pluralism, he resigned the government of Perugia at this time. On December 5, 1580, he opted for the suburbicarian Diocese of Porto-Santa Rufina. During this period, he was Sub-Dean of the College of Cardinals.
