Fürstentum Tarent
Ferdinand I of Naples, also known as King Ferrante, united the Principality of Taranto to the Kingdom of Naples, at the death of his wife, Isabella of Taranto (Clermont). The principality ended, but the kings of Naples continued giving the title of Prince of Taranto to their sons, firstly to the future Alfonso II of Naples, Duke of Calabria, eldest son of Isabella.
