The list of cardinal-nephews includes at least fifteen, and possibly as many as nineteen popes[8] (Gregory IX, Alexander IV, Adrian V, Gregory XI, Boniface IX, Innocent VII, Eugene IV, Paul II, Alexander VI, Pius III, Julius II, Leo X, Clement VII, Benedict XIII, and Pius VII; perhaps also John XIX and Benedict IX, if they were really promoted cardinals; as well as Innocent III and Benedict XII, if in fact they were related to their elevators); one antipope (John XXIII); and two or three saints (Charles Borromeo, Guarinus of Palestrina, and perhaps Anselm of Lucca, if he was really a cardinal).
[15] Pope Paul IV (1555–1559), in his old age, was said to have "fallen almost completely under the cardinal-nephew's influence";[16] Paul IV's cardinal-nephew, Carlo Carafa, was accused in August 1558 by a Theatine of seducing a Roman noble woman, Plautila de' Massimi, who had come into possession of an inordinate amount of money and jewelry, but the accusations were dismissed by the pontiff.
[20] The Cardinal Nephew was also the correspondence liaison for all papal nuncios and gubernatorial legates, and the prefect for two congregations: the Consulta and the Congregazione del Buon Governo.
[25] However, these formal functions only came into force during the pontificates of unusually weak Popes; most Cardinal Nephews were the de facto rubber stamp of the pontiff himself.
[19] A thorough financial analysis of Borghese's cardinalate by Volker Reinhardt (based on a series of extant account books) examines the strategies Borghese used to build up wealth during his uncle's pontificate and non-ecclesiastical assets before his uncle's death, which Volker considers to be exemplary of Baroque papal families.
[31] Pope Gregory XIV (1590–1591) began the practice of creating cardinal-nephews whose formal appointment coincided de facto with their nomination, and was thus separate from the ordinal process for creating cardinals,[27] and, when he fell ill, he authorized his cardinal-nephew, Paolo Emilio Sfondrato, to use the Fiat ut petitur, a power which was later diminished at the urging of the college.
[32] Paul V issued a motu proprio on April 30, 1618, formally bestowing on his cardinal-nephew the same authority Pope Clement VIII had given to Pietro Aldobrandini, beginning what historian Laurain-Portemer calls "l'age classique'" of nepotism.
[24] These benefices and offices netted Ludovisi more than 200,000 scudi annually, and he is considered to have exercised "more unlimited authority" than any previous cardinal-nephew.
In fact, papal historian Valérie Pirie considers not having a nephew a "tremendous asset for a would-be Pope" as it left the position open for an ally cardinal.
[38] Many historians consider Olimpia Maidalchini, the sister-in-law of Pope Innocent X (1644–1655), to have been a de facto Cardinal Nephew; the position was formally held by her son, Camillo Pamphili, then her nephew, Francesco Maidalchini (after Pamphili renounced his cardinalate in order to wed), and (after Francesco proved incompetent) Camillo Astalli, her cousin.
[41] Another papal historian Ludwig von Pastor notes that "the misfortune of Pope Pamphilj was that the only person in his family who would have had the qualities necessary to fill such a position was a woman".
[4] However, Innocent XI backed down after thrice failing to achieve the support of the majority of his cardinals for a bull banning nepotism,[42] which had been tediously composed between 1677 and 1686.
[43] Innocent XI refused entreaties from within the papal court to bring his only nephew, Livio Odescalchi, the prince of Sirmio, to Rome,[44] although he did elevate Carlo Stefano Anastasio Ciceri, a distant relative, cardinal on September 2, 1686.
[4] Alexander VIII also undid another reform of Innocent XI by restoring the revenues of the former Chancery to the Vice-Chancellor, who was, at the time, his cardinal-nephew, Pietro Ottoboni.
[22] Edith Standen, a consultant to the Metropolitan Museum of Art, calls Ottoboni the "last and certainly not least magnificent example" of the "splendor of an extinct species, the Cardinal-Nephew".
[48] Pope Innocent XII (1691–1700) issued a papal bull on June 22, 1692, Romanum decet pontificem, banning the office of Cardinal Nephew, limiting his successors to elevating only one cardinal relative, eliminating various sinecures traditionally reserved for cardinal-nephews, and capping the stipend or endowment the nephew of a Pope could receive to 12,000 scudi.
[49] In 1694, Innocent XII's series of reforms was concluded with an expensive campaign to eliminate the "venality" of offices while reimbursing their current holders.
[43] These reforms are viewed by some scholars as a delayed reaction to the financial crisis created by the nepotism of Pope Urban VIII (1623–1644).
Therefore, he commissioned a genealogist to discover (and inflate) some trace of nobility in the Onesti lineage, an endeavor which yielded only a circuitous connection to Saint Romualdo.
[53] After the turbulent 1800 papal conclave, Pope Pius VII (1800–1823) shunned the institution of the cardinal-nephew and instead relied on his Cardinal Secretary of State, Ercole Consalvi.
[41] A notable exception is Pope Gregory XV (1621–1623) who declined on his death bed the request of Ludovico Ludovisi to name more relatives to the college, saying he had "enough to account to God for the unworthy ones he had appointed".
[61] An analysis of the five papal conclaves between 1605 and 1644 shows that cardinal-nephews were generally unsuccessful in electing their chosen candidates, although the victor was usually a cardinal created by the deceased Pope.
[68] Nepotism is a common feature in the history of governance, particularly in cultures where identity and loyalty are determined more at the level of the family than that of the nation-state.
