Prince Filippo, Duke of Calabria

Prince Filippo of Naples and Sicily, Duke of Calabria, Infante of Spain (13 June 1747 – 19 September 1777) was the eldest son and heir apparent of Charles III of Spain, but was excluded from the succession to the thrones of Spain and Naples due to him being mentally and physically disabled. 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 with a household of personal staff until his death from smallpox.
