Nepotism
Nepotism is favoritism granted to relatives. The term originated with the assignment of nephews to cardinal positions by Catholic popes and bishops. Nepotism can occur in various fields including: politics, entertainment, education and business.
Origins
The term comes from Italian word nepotismo, which is based on Latin root nepos, meaning nephew or grandson. Since the Middle Ages and until the late 17th century, some Catholic popes and bishops, who had taken vows of chastity, and therefore usually had no legitimate offspring of their own, gave their nephews such positions of preference as were often accorded by fathers to son.
Several popes elevated nephews and other relatives to the cardinalate. Often, such appointments were a means of continuing a papal "dynasty". For instance, Pope Callixtus III, head of the Borgia family, made two of his nephews cardinals; one of them, Rodrigo, later used his position as a cardinal as a stepping stone to the papacy, becoming Pope Alexander VI. Alexander then elevated Alessandro Farnese, his mistress's brother, to cardinal; Farnese would later go on to become Pope Paul III.
