Nepotism: To allocate favour or advantage to family
The origin is the Italian word nepotismo, which comes from the Latin nepos meaning nephew. Notoriously, some less scrupulous Popes appointed their nephews as cardinals to maintain dynastic succession without flouting their vow of chastity.
For instance, Pope Callixtus III, head of the Borgia family, made two of his nephews cardinals. One of them, Rodrigo, later became Pope Alexander VI.[6]
Alexander then elevated Alessandro Farnese, his mistress's brother, to cardinal; Farnese would later go on to become Pope Paul III.[7] Paul III also engaged in nepotism, appointing two nephews, aged 14 and 16, as cardinals.
What's in a name?
In 1692, Pope Innocent put an end to this practice in the Vatican, but appointing what the Spanish call 'los tuyos' (family members) has remained endemic in other spheres.
Napoleon Bonaparte, for example, appointed his brother Louis, King of the Netherlands.
