Biography
Carlo Filiberto was born in 1649 as the second son of Filippo II Francesco d'Este, and Margherita of Savoy (illegitimate daughter of Charles Emmanuel I) inherited the Marquisate of Dronero from his father, becoming the founder of the short Este-Dronero line, which died out in 1734 with the death of his son Gabriele d'Este without male heirs. The Este family of Dronero's inheritance was at the centre of a long dispute between the Doria del Maro and the Birago di Vische, resolved in favour of the latter with the investiture of the Marquisate of Dronero on 13 June 1737.
Carlo Filiberto was captain of the armour of Madame Royale Marie Jeanne Baptiste of Savoy-Nemours.
In 1697 Carlo Filiberto, together with his son Gabriele, was sent as Governor to Savoy: "a country where it always rains; and as soon as the rain falls the cold makes itself felt with violence" and "there is no civil society, there is no walking".
