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 who bore the title of Duca di Corgna, and Jacopa Ciocchi del Monte. He had a brother Ascanio, who became an important commander of papal armies and Duca della Corgna. His mother was the sister of Pope Julius III and niece of Cardinal Antonio Maria Ciocchi del Monte. The family owned the Marchesato di Castiglione del Lago on Lake Bolsena. Fulvio was a Marchese della Corgna.
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. He was named a Protonotary Apostolic, as well as Archpriest of the Cathedral of S. Lorenzo of Perugia.
On March 5, 1550, he was appointed Bishop of Perugia by his Uncle Julius. He became Papal Legate of Ascolo-Piceno, Reate and Monteleone di Spoleto on December 15, 1550.  It was Fulvio della Corgna who was responsible for the founding of the seminary in Perugia and for inviting the Jesuits to the city to establish a college, the first Rector of which was Everard de Mercœur (Mercurian).
In 1553, Cosimo de' Medici, Duke of Florence, fearing that the fighting in Tuscany might expand into a larger war between the Empire (Charles V) and France (Henri II), which would be severely damaging to his territories, urgently requested the Pope to send negotiators to work out an understanding. Julius sent Cardinal Fulvio della Corgna to Florence and Cardinal Niccolò Caetani de Sermoneta to Siena. When nothing came of their efforts, Pope Julius III himself travelled to Viterbo. On August 2, the French, who had invaded Tuscany under Marshal Blaise de Montluc, were defeated at the Battle of Marciano, and forced to retreat into Siena, where they fomented a coup-d-état in their own interests. But the fact that Vercelli had recently fallen to Marshal de Brissac and the Duke of Savoy had been killed (August 16) gave the French, enjoying one success after another, the courage to decline to settle. The Tuscan War was just beginning. Duke Cosimo of Florence requested that Cardinal della Corgna be named administrator of Spoleto to quell disturbances that had broken out there; on March 22, 1553, therefore, the Cardinal resigned the government of Perugia to become Administrator of Spoleto, on the appointment of Pope Julius III. His seat in Perugia was taken by his nephew, Ippolito della Corgna.
Conclave of 1555
He was a participant in both the papal conclave of April 1555 that elected Pope Marcellus II (Marcello Cervini), and the papal conclave of May 1555 that elected Pope Paul IV (Gian Pietro Carafa). Pope Paul IV deprived him of the administration of Spoleto in 1555, in favor of Cardinal Alessandro Farnese, one of Carafa's friends, who had administered the diocese of Spoleto under his uncle Paul III in the 1540s. 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. His Vicar-General was Donato Torri. It was at this time that he founded the seminary in Perugia. On February 7, 1565, he opted for Sant'Angelo in Pescheria, another deaconry assigned as titulus, on February 7, 1565.
Conclaves of 1565-1566 and 1572
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 cardinal-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. Nonetheless he generously provisioned the many pilgrims who were coming from Perugia to participate in the Jubilee of 1575. On December 5, 1580, Cardinal della Corgna opted for the suburbicarian Diocese of Porto-Santa Rufina. During this period, he was Sub-Dean of the College of Cardinals.
