Infante Philip, Duke of Calabria

Who was Infante Philip, Duke of Calabria?

Philip of Naples and Sicily, Duke of Calabria was the eldest son and heir of Charles III of Spain, but was excluded from the succession to the thrones of Spain and Naples due to his imbecility. His younger brothers, Charles IV of Spain and Ferdinand I of the Two Sicilies replaced him in the succession. When his father became King of Spain in 1759, Philip remained in Naples where he lived until his death, age thirty, of smallpox. It can be claimed by looking at the portrait to the right, that Infante Philip may have been the first documented case of what would later be termed as Down Syndrome.
