Ippolito d'Este. King Philip II favored d' Olera, Ghislieri, Ricci, Morone, and Pacecho. When the Spanish Ambassador, Don Luis Requesens de Zuniga, arrived in Rome on 21 December 1565, however, he carried instructions to support Ghislieri and Morone. He was suspicious of the orthodoxy of Cardinal Morone though, and he feared that Cardinal Farnese might pursue a vendetta against Spain for the murder of his father if he were to become pope. The Emperor Maximilian II was informed by his agent in Rome, Nosti Camiani, that the most favored cardinals were: d' Olera, Boncompagni, Suau, Sirleto, Simonetta, Gianbernardino Scotti, and Michele Ghislieri. He wrote directly to Cosimo III of Florence, asking for his assistance in the election. Cosimo replied that he was no longer in the business of influencing papal elections, but agreed to serve the Emperor's wishes. He was in fact very active behind the scenes.

Cardinal Farnese, nephew of Pope Paul III, had in his faction Cardinals Corregio, Gambara, Savelli, Paleotti and Orsini. Farnese was personally beloved by the Roman populace as a patron of the poor and a Maecenas of the arts. The cardinals who had been created by Paul IV were also supporting Farnese. They included: Vitelli (the Camerlengo), Capizucchi, Reuman Suau, Rebiba, Ghislieri, and D' Olera. The cardinals created by Pius IV numbered nine, and under certain circumstances might draw four more. The Gonzaga faction had six members. The cardinals created
