Pope Innocent VIII [SEP] Introduction
Pope Innocent 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. Son of the viceroy of Naples, Battista 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. After intense politicking by Della Rovere, Cibo was elected pope in 1484. King Ferdinand I of Naples had supported Cybo's competitor, Rodrigo Borgia.
