List of cardinal-nephews



A cardinal-nephew is a cardinal elevated by a pope who was his uncle, or more generally, his relative. The practice of creating cardinal-nephews originated in the Middle Ages, and reached its apex during the 16th and 17th centuries. From the Avignon Papacy (1309–1377) until Pope Innocent XII's anti-nepotism bull, Romanum decet pontificem (1692), nearly every pope who appointed cardinals appointed at least one relative to the College of Cardinals, including every Renaissance-era pope.

Although nephews were the most common relation to be elevated to the College, other family members include (legitimate, illegitimate, or adopted) sons and grandsons, brothers, grandnephews, cousins and even uncles. At least 15, and possibly as many as 19 cardinal-nephews were later elected pope (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, 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 became antipope (John XXIII), and two or three were canonized (Charles Borromeo, Guarinus of Palestrina, and perhaps Anselm of Lucca, if in fact he was really elected cardinal).

Similarly created cardinals include cardinal-nephews of antipopes and papal relatives made cardinals by other popes.

Notes on symbols
Because statements concerning the familial ties of popes and cardinals prior to 14th century are often of much later origin, some sources regard their factual accuracy as dubious. Thus, individuals are marked with: Occupants of the curial office of the Cardinal Nephew are denoted with †.
