Louis, Duke of Blacas

He translated into French, under the title Histoire de la monnaie romaine (Paris 1866), the Geschichte des Römischen Münzwesens (History of Roman Coinage) of Theodor Mommsen (Berlin 1860), with additional notes signed B.

[citation needed] After his father's death, Blacas defended him against allegations of unscrupulous gains made by the Duke of Ragusa.

Blacas was a devoted follower of the duc d'Angoulême's successor, the comte de Chambord, whom he had known since childhood and whom he served all his life.

However, contrary to his father and to his own son (who later served as mayor and deputy), Blacas did not directly take part in the political life of the Second Empire.

They had only one daughter: He died in Venice at the Palazzo Cavalli, the residence of the comte de Chambord, after planning a study of Venetian coinage.
