Luigi d'Aragona (1474–1519) was an Italian Roman Catholic cardinal. He had a highly successful career in the church, but his memory is affected by the allegation that he ordered the murder of his own sister and two of her children.

Pope Innocent VIII, born Giovanni Battista Cybo, 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. 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.
