Pope Innocent VIII

Pope Innocent VIII (Latin: Innocentius VIII; Italian: Innocenzo VIII; 1432 – 25 July 1492), born Giovanni Battista Cybo (or Cibo), was head of the Catholic Church and ruler of the Papal States from 29 August 1484 to his death, in July 1492. Son of the viceroy of Naples, Cybo spent his early years at the Neapolitan court. He became a priest in the retinue of Cardinal Calandrini, half-brother to Pope Nicholas V (1447–55); Bishop of Savona under Pope Paul II; and with the support of Cardinal Giuliano Della Rovere he was made a cardinal by Pope Sixtus IV. After intense politicking by Della Rovere, Cybo was elected pope in 1484. King Ferdinand I of Naples had supported Cybo's competitor, Rodrigo Borgia. The following year, Pope Innocent supported the barons in their failed revolt.

During his papacy, Pope Innocent issued a papal bull on witchcraft named Summis desiderantes affectibus. In March 1489, Cem, the captive brother of Bayezid II, the sultan of the Ottoman Empire, came into Innocent's custody. Viewing his brother as a rival, the Sultan paid Pope Innocent not to set him free. The amount he paid to Pope Innocent was 120,000 crowns (an amount equal to all of the annual revenue to the Vatican) in addition to some holy relics and another sum of money to be paid annually. Any time the Sultan threatened war against the Christian Balkans, Innocent threatened to release his brother. On 28 January 1495, Cem was released by Innocent's successor, Pope Alexander VI, into the custody of the army of King Charles VIII of France.

In 1432, Giovanni Battista Cybo was born in Genoa, the son of Arano Cybo and wife Teodorina de Mari. His father was from an old Genoese family of Greek ancestry, a viceroy of Naples and then a senator in Rome under Pope Calixtus III. Giovanni Battista's early years were spent at the Neapolitan court. While in Naples he was appointed a Canon of the Cathedral of Capua, and was given the Priory of Santa Maria d'Arba in Genoa. After the death of King Alfonso (1458), friction between Giovanni Battista and the Archbishop of Genoa induced him to resign his canonry, and to go to Padua and then to Rome for his education.

In Rome he became a priest in the retinue of Cardinal Calandrini, half-brother to Pope Nicholas V (1447–55). In 1467, he was made Bishop of Savona by Pope Paul II, but exchanged this see in 1472 for that of Molfetta in south-eastern Italy. In 1473, with the support of Giuliano Della Rovere, later Pope Julius II, he was made cardinal by Pope Sixtus IV, whom he succeeded on 29 August 1484 as Pope Innocent VIII.

The papal conclave of 1484 was rife with factions, while gangs rioted in the streets. In order to prevent the election of the Venetian Cardinal Barbo, Camerlengo of the Sacred College of Cardinals, on the evening before the election, after the cardinals had retired for the night, the Dean of the College of Cardinals, Cardinal Giuliano della Rovere, nephew of the late Pope, and Cardinal Borgia, the Vice-Chancellor, visited a number of cardinals and secured their votes with the promise of various benefices.

It was claimed that Cardinal della Rovere met secretly with Cardinal Marco Barbo in order to secure him more votes to become pope if he was promised a residence, though Barbo refused in fear it would make the conclave invalid due to simony. Cardinal della Rovere then met with Borgia, who disliked Barbo and wished to block his election, with an offer to turn their votes over to Cybo, promising them benefits for doing so.

Shortly after his investiture, Innocent VIII addressed a fruitless summons to Christendom to unite in a crusade against the Turks. A protracted conflict with King Ferdinand I of Naples was the principal obstacle. Ferdinand's oppressive government led in 1485 to a rebellion of the aristocracy, known as the Conspiracy of the Barons, which included Francesco Coppola and Antonello Sanseverino of Salerno and was supported by Pope Innocent VIII. Innocent excommunicated Ferdinand in 1489 and invited King Charles VIII of France to come to Italy with an army and take possession of the Kingdom of Naples, a disastrous political event for the Italian peninsula as a whole. The immediate conflict was not ended until 1494, after Innocent VIII's death.

Bayezid II ruled as Sultan of the Ottoman Empire from 1481 to 1512. His rule was contested by his brother Cem, who sought the support of the Mamluks of Egypt. Defeated by his brother's armies, Cem sought protection from the Knights of St. John in Rhodes. Prince Cem offered perpetual peace between the Ottoman Empire and Christendom. However, the sultan paid the Knights a large amount to keep Cem captive. Cem was later sent to the castle of Pierre d'Aubusson in France. Sultan Bayezid sent a messenger to France and requested Cem to be kept there; he agreed to make an annual payment in gold for his brother's expenses.
