November 1105 CE
Members of the Roman aristocracy, with the support of the German king Henry V, set up another antipope to replace Pope Paschal II, electing Maginulfo, the Archpriest of St. Angelo in Peschiera, while Paschal II is outside of Rome.
After his election, Maginulfo takes the papal name of Sylvester IV, is consecrated in the Church of St. Maria Rotonda (the Pantheon), and is enthroned in the Lateran on November 18, 1105.
When Paschal II returns to Rome the next day, Sylvester IV leaves for Tivoli and finally settles in Osimo, Province of Ancona, under the protection of Count Guarniero di Ancona.
