The title referred to the island of Dino in the Tyrrhenian Sea, off Praia a Mare in Calabria.
It was created on 9 November 1815 by King Ferdinand for the French diplomat and statesman Charles-Maurice de Talleyrand-Périgord, in recognition of his service at the Congress of Vienna.
Alexandre and Maurice were styled Duke of Dino, but the transfer of the associated property within the family had no power to alter the order of succession according to the original patent.
The senior descendant of Edmond was confirmed as Duke of Dino by the King of Italy in 1912, the Kingdom of the Two Sicilies having ended in 1861 during the process of Italian unification.
In 1975, the exiled former King of Italy Umberto II issued a diploma confirming Manuel Gonzalez de Andia, Marquis of Villahermosa as Duke of Dino, with a remainder failing male issue to his elder daughter Maria Louisa and her husband.
